Mark Driscoll's Scottsdale Church to Launch August 7

Although a group of people has been meeting in Scottsdale, AZ for several weeks, the official launch of Mark Driscoll’s The Trinity Church has been slated (“penciled in”) for August 7, 2016.
According to this video (click through to watch), the church still has to get some design elements in place. The plans sound pretty ambitious. It is not clear that the building isn’t viewed as temporary. The building’s “mid-century modern” style figures prominently in the “groovy” church. His launch announcement is a 7:30 into the clip.

In addition to the video, here is what Driscoll says about the launch (written message accompanying the video):

We are in our core launch team phase gearing up for our public opening this fall around the time that school begins. Right now, we have a family style Bible study with the kids present every Sunday at 9:30 am. If you are interested in our church launch, you are welcome to join us. This week Pastor Mark continues his series in 1 John: The Father Heart of God. We will be in 1 John 4:1-6 if you want to read ahead.
Thank you, thank you, thank you to all that have been helping at our work parties. You have put in over 1000 hours helping us prepare our building for the public launch. We ave enjoyed meeting and working alongside some wonderful hard working people.
This weekend in observance of Memorial day we will not be having a work party on Saturday or Sunday after the Bible study. Lets take a much needed break and also take some time to pray for our military men and women and their families as well as veterans. We appreciate your service and want to honor you.If you attend the Bible study this Sunday we want to give you a gift.
After the Bible study this Sunday we will have an “Ice Cream Sunday” with lots of toppings and bouncy houses blown up for the kids.
In the next month or so, we hope to have our kids ministry building ready to start childrens ministry in the “backyard”. After that, our plan is to have the main room that we call the “living room” ready for church services including the worship band and singing as we gear up for two morning church services. For that to happen, we are giving the old room a fresh makeover in keeping with the midcentury modern Brady Bunch vibe. Yes, it’s groovy.
Thank you to everyone who has given of your finances, prayers, and service. It’s amazing to see how much can get done when hard working people pull together for the cause of Jesus Christ!

Maybe The Trinity Church can get these guys back together for the big launch.

Former Ex-Gay Leader Alan Chambers Says Ex-Gay Movement Is Gasping for Air

In a massive report by Mark Potok and available on the Southern Poverty Law Center website, former president of Exodus International Alan Chambers answers a question from Mark Potok about the future of ex-gay ministry. When Exodus was open for business, it was the largest organization dedicated to sexual reorientation.
Potok’s question is followed by Chambers’ answer.

What do you feel is the future of the ex-gay movement here and abroad?
I honestly believe it is gasping for air. I don’t believe there will ever again be an organization with the size or scope of Exodus International.
My hope is, as I stated very clearly during my closing speech at the Exodus conference in 2013, that every ministry focused on changing orientation will close. I do not believe the ministries or churches that seek to serve people who choose to be celibate are a danger unless they place conditions or qualifications on God’s love.
There will never be a consensus on science or Scripture or politics or much of anything for that matter, but we can seek to unite around the gospel of grace and love and peace. That is a life changing and revolutionary paradigm.

I can reveal that I had an informal role by providing information to the SPLC attorneys in the JONAH case. I know that makes me a heretic in the minds of some on the religious right. I also shopped at Target last night.
The problem is not with people following their religious beliefs about sexual behavior, even if it means celibacy from homosexuality. The problem is the misguided, discredited belief that parental failings cause homosexuality and the resultant “therapies” which follow from such beliefs. If you have the stomach to read through Potok’s report, you will read some bizarre things done in the name of sexual reorientation. You can also read this post for a brief account.

Information and Misinformation on Gender Dysphoria from Wallbuilders and the American College of Pediatricians, Part One

Tuesday on Wallbuilders Live, Dr. Michelle Cretella represented tiny pediatric breakaway group the American College of Pediatricians. She briefly discussed the organization’s position paper on responding to gender identity issues. In doing so, she said something which caught my irony sensor. It also occurred to me, as it repeatedly has in the discussion of gender dysphoria, how difficult it is to avoid taking extreme positions.
Listen to her response to a question from host Rick Green about how much harm gender dysphoria is causing.

I want to address two claims that came up in this segment. In this post, I address the claim that 80% of gender dysphoric children will accept their biological sex with therapy. In a future post, I will write about the claim about suicide rates.
Cretella says:

They’re [advocates for transgender children] cooperating with, at least, mental confusion.  You know, initially, we know that there is psychiatric literature that shows if you work with these children one on one and with their families, the vast majority, over 80% will come to accept their biological sex after puberty before adulthood. So yes, to put these children to reaffirm their confused thinking, to put them on puberty blockers, and then cross-sex hormones to make them quote unquote the other gender, you are permanently sterilizing children. It’s insanity.

Cretella is correct that persistence rates are low (gender dysphoria continuing into adulthood) among gender dysphoric children, but this is not the case with adolescents who remain gender dysphoric or those who experience it with an adolescent onset. In their paper, ACP uses the American Psychiatric Association’s DSM-V as an authority. The section of the DSM-V cited by ACP supports the claim about persistence but does not fully support Cretella’s claim about the role of therapy.

Rates of persistence of gender dysphoria from childhood into adolescence or adulthood vary. In natal males, persistence has ranged from 2.2% to 30%. In natal females, persistence has ranged from 12% to 50%. Persistence of gender dysphoria is modestly correlated with dimensional measures of severity ascertained at the time of a childhood baseline assessment. In one sample of natal males, lower socioeconomic background was also modestly correlated with persistence. It is unclear if particular therapeutic approaches to gender dysphoria in children are related to rates of long-term persistence. Extant follow-up samples consisted of children receiving no formal therapeutic intervention or receiving therapeutic interventions of various types, ranging from active efforts to reduce gender dysphoria to a more neutral, “watchful waiting” approach. It is unclear if children “encouraged” or supported to live socially in the desired gender will show higher rates of persistence, since such children have not yet been followed longitudinally in a systematic manner. For both natal male and female children showing persistence, almost all are sexually attracted to individuals of their natal sex. For natal male children whose gender dysphoria does not persist, the majority are androphilic (sexually attracted to males) and often self-identify as gay or homosexual (ranging from 63% to 100%). In natal female children whose gender dysphoria does not persist, the percentage who are gynephilic (sexually attracted to females) and self-identify as lesbian is lower (ranging from 32% to 50%). (APA, DSM-V, p. 455)

To the DSM-V, I can add the description of persistence developed by the World Professional Association for Transgender Health (WPATH) in their standards of care.

An important difference between gender dysphoric children and adolescents is in the proportion for whom dysphoria persists into adulthood. Gender dysphoria during childhood does not inevitably continue into adulthood.V Rather, in follow-up studies of prepubertal children (mainly boys) who were referred to clinics for assessment of gender dysphoria, the dysphoria persisted into adulthood for only 6–23% of children (Cohen-Kettenis, 2001; Zucker & Bradley, 1995). Boys in these studies were more likely to identify as gay in adulthood than as transgender (Green, 1987; Money & Russo, 1979; Zucker & Bradley, 1995; Zuger, 1984). Newer studies, also including girls, showed a 12–27% persistence rate of gender dysphoria into adulthood (Drummond, Bradley, Peterson-Badali, & Zucker, 2008; Wallien & Cohen-Kettenis, 2008).
In contrast, the persistence of gender dysphoria into adulthood appears to be much higher for adolescents. No formal prospective studies exist. However, in a follow-up study of 70 adolescents who were diagnosed with gender dysphoria and given puberty-suppressing hormones, all continued with actual sex reassignment, beginning with feminizing/masculinizing hormone therapy (de Vries, Steensma, Doreleijers, & Cohen-Kettenis, 2010).
Another difference between gender dysphoric children and adolescents is in the sex ratios for each age group. In clinically referred, gender dysphoric children under age 12, the male/female ratio ranges from 6:1 to 3:1 (Zucker, 2004). In clinically referred, gender dysphoric adolescents older than age 12, the male/female ratio is close to 1:1 (Cohen-Kettenis & Pfäfflin, 2003). (WPATH, p. 11).

The irony of Cretella’s confidence in psychiatric intervention relates to the expulsion from ACP membership of George Rekers who was infamous for his own personal decline and his discredited treatment approach to what was then called gender identity disorder. In fact, we don’t know the role, if any, therapy plays in influencing the current persistence rates. While there is reason to think parental permission to transition in childhood might increase the persistence rates, there isn’t sufficient research to say for sure.
After listening to Cretella and reading the ACP paper, I wonder what the ACP recommends for the 10-20% of people with gender dysphoria persisting into the late teens. Do they favor reassignment for those persons? They focus on the data which make their point but don’t seem to have an answer for the rest of the people involved.
Another problem with ACP’s confidence in psychiatric interventions for gender dysphoria is that they also oppose a frequent end point in the trajectory of many gender dysphoric children: homosexuality (see image at the end of the post). One of the reasons George Rekers tried to re-orient gender dysphoria was to prevent homosexuality. Furthermore, one of the prime objectives of reparative therapists like Joseph Nicolosi is to prevent homosexuality via the alteration of parenting behaviors toward gender nonconforming children. ACP should stop pretending to sympathize with gender dysphoric children when they also write letters to school personnel promoting reparative change therapy for gay people.
Summary
Cretella is right that studies of gender dysphoric children (mostly with boys) find low rates of persistence of gender dysphoria into adulthood. However, she should have distinguished between prepubescent children and teens. The outcomes for these two groups do not appear to be the same. No doubt her listeners will not make that distinction.
Cretella was wrong to invoke psychiatric treatment as the reason for low persistence rates. If anything, some treatments have been shown to be harmful in some cases while others may not be harmful but may not cause a reduction in gender dysphoria. From her presentation, one could get the impression that advocates for gender dysphoric children know these treatments work but are motivated to undermine the natural family and therefore withhold appropriate medical care. While there is strong disagreement among experts and some advocates might oppose traditional families, it is simply not true that gender dysphoria could be easily treated if only activists would get out of the way.
Another important factor is that the treatment advocated by Cretella and the ACP is an outdated, discredited, psychoanalytically based approach which has not shown success. Even among those in the mainstream who are skeptical of puberty blocking drugs, the treatments advocated by ACP are rejected.
Gender Dysphoria After Childhood
The following image comes from a 2012 study by Devita Singh on gender dysphoric boys. Note the columns titled “sexual orientation in fantasy” and “sexual orientation in behavior.” By far, the most common end point for gender dysphoric children across studies is some level of same sex attraction. Gay advocates have in the past confided to me that they are ambivalent about supporting interruption of puberty because such interventions may interfere with a natural homosexual outcome. Please see this common sense article by Michael Bailey and Eric Vilain on the dilemma many parents of gender dysphoric children face.

David Barton Inflates Numbers for Posttraumatic Stress Disorder in Women

Yesterday, David Barton’s Wallbuilders radio program hosted Michelle Cretella, president of the American College of Pediatricians. Barton and his co-host Rick Green once mistakenly called ACP the “leading association” of pediatricians.
Cretella was on the program to tout the ACP’s stance on transgender issues; I may have more to say about her interview in subsequent posts. However, after the interview, Barton made a claim which he offered as a way to say women should not be in combat. At about 23 minutes into the broadcast, Barton said:

Do you want to go where stats lead you? And she [Cretella] mentioned, what did she say the suicide rates were like 20 times higher in the kids who were being pushed in the transgender direction. And that reminded me of something that a two star General told me not long ago. And he said, when you look at what’s happening right now with women in the military. Women are not allowed in combat, you know they made that decision to change that recently but they’re not in combat units yet. But over the last several years of women’s roles in Afghanistan where they are not allowed in combat, of the women who are back, 90% are suffering from PTSD, only 10% of guys coming back suffering from PTSD. So we got 90% PTSD in women coming back and they’re not in combat. I know! Let’s put them in combat.

After citing a misleading stat from Cretella, he gives his audience one of his own.
I think it is possible that a two-star General who opposes women in combat did tell Barton this. However, now Barton is spreading undocumented and most likely false information to his audience. Some research does find that women experience more frequently than men do, the difference isn’t as great as Barton’s General told him. Here are two VA sources on the matter:

How many women Veterans have PTSD?

Among women Veterans of the conflicts in Iraq and Afghanistan, almost 20 of every 100 (or 20%) have been diagnosed with PTSD. We also know the rates of PTSD in women Vietnam Veterans. An important study found that about 27 of every 100 female Vietnam Veterans (or 27%) suffered from PTSD sometime during their postwar lives. To compare, in men who served in Vietnam, about 31 of every 100 (or 31%) developed PTSD in their lifetime. (link)

Twenty percent is a tragedy but it is a long way from 90%.
According to a recent VA source, the rates of PTSD are about the same for military men and women seeking care from the VA.

“In the general population, women are twice as likely as men to develop posttraumatic stress disorder,” noted Dr. Sonja Batten, VA’s Deputy Chief Consultant for Specialty Mental Health. “But among recent returnees seeking care at VA, PTSD rates among men and women are the same. Statistics such as these suggest the need to better understand the role of gender in PTSD, particularly as it may impact our Veterans seeking care.”

On PTSD, Barton hasn’t had a good track record.
It might not be today, but I intend to get back to the claim that the transgender teen suicide rate is 20 times higher than some other teens.

With David Barton as Principal Officer, Non-Profit Mercury One Again Gave $100k to Barton’s Wallbuilders For Disaster Relief

Deja vu all over again. As was true in 2013, Mercury One with David Barton as principal officer and one of three board members gave $100k to David Barton’s Wallbuilders non-profit. Again in 2014, Barton is listed as Mercury One’s principal officer:
Mercury One 990 2014
And as last year, Barton is one of three board members along with Beck associate Joseph Kerry and Beck’s wife Tania.
Mercury One 990 Board 2014
This year Barton got a 4% raise:
mercury one 990 Wallbuilders 2014
See last year’s post for the possible problems with this.
Last year the funds were given to Wallbuilders because of their mission related to history. This year the 990 says “proceeds were used to provide help and resources to individuals affected by unforeseen disasters.” I took a quick Google look for something Wallbuilders did in 2014 or 2015 to help people through “unforeseen disasters” (other than Donald Trump, what disasters are foreseen?) and I couldn’t figure out what Wallbuilders did to help people with disasters (do bad history lessons count?).
Mr. Barton or Rick Green, if your catching up on your Throckmorton blog reading, could you do a Wallbuilders’ program where you outline how Wallbuilders spent over $100k on disaster relief?

Gospel for Asia Fails K.P. Yohannan's Own Stewardship Test

Yesterday, I noted how K.P. Yohannan criticized missionary hospitals and schools in his first book but now funds them in India with millions of donor dollars.
Today, at the suggestion of a reader, I take a look at similar criticism in his third book, originally titled Why the World Waits.
On pages 245-246 Yohannan’s 2004 edition re-titled Come, Let’s Reach the WorldYohannan poses some questions prospective donors should ask about mission organizations. While I don’t know the answers to all of them as applied to GFA, the answers I do know suggest Yohannan’s GFA fails his own test.
From the book:

Ask questions relating to financial and administrative standards.
1. Is an annual audit done by a certified accountant?

Until I reported on errors in the 2013 audit, GFA published an audit available by request. According to GFA sources, the most recent audit for 2014 has been completed but GFA won’t release it.

2. Is the audit made available to the organization’s constituency?

Not currently. For many years, GFA refused to post their audit citing security concerns. However, until recently, one could request a copy by mail. Now, GFA will not release an audit of the U.S. affiliate. To my knowledge, there is no public audit of the Indian organizations (i.e., GFA-India, Believers Church).

3. Is the ratio of spending for field ministry considerably greater than for administration? (It should be at least 80 percent for actual ministry.)

The actual ratio is a matter of debate. For many years, GFA claimed to send 100% of donated funds to the field but an analysis by Jason Watkins casts doubt on that claim. There is ample reason to suspect that many donations have gone to pay for hospital construction as well as other projects not designated by donors.

4. Are all documents, assets and the like in the name of the organization (not an individual leader)?

No, Believers’ Church* policy requires that property and assets be listed under the name of K.P. Yohannan as Metropolitian bishop along with the church.

5. What are the major items of expense? (If funds go primarily for properties, hospitals and schools rather than for actual field evangelism, be extremely cautious to check them out.)

As I have documented, GFA has amassed an empire of for profit schools and hospitals. They own a rubber plantation, a finance company, rental properties, and sponsor a professional soccer team. An Indian tax court found that GFA did not spend “substantial” funds as donors intended. According to Watkins financial review, only a tiny portion of the donations went to evangelistic activities.

6. Is the missionary or group receiving any financial assistance from other sources?

GFA receives funds primarily from donors in the U.S., Canada and the UK.

7. Is there a written agreement to declare all sources of income for any given project?

In the past, GFA promised to spend funds in accord with donor intent. After losing membership in the Evangelical Council for Financial Accountability, GFA changed their promise to make it more explicit that the organization may use donated funds for purposes other than donors intend.

8. Is the group registered with the government as a charitable or nonprofit organization?

Yes.

9. Are finances and financial records handled only by the leader and his relatives? (If this is the case, then you have good enough reason not to support him.)

According the Believers’ Church constitution, funds cannot be spent without the oversight of the Metropolitan Bishiop (Yohannan). He has relatives on his boards (his wife, son, daughter, son-in-law and niece are on various boards with oversight over the funds).

10. Are the accounts jointly operated (that is, at least two people responsible for handling the funds)?

As noted above, Yohannan has the final say on how money is spent. There is a committee which exercises oversight but Yohannan has veto power over all actions of the Believers’ Church. His name is on the deed to all properties.

11. Are written and signed receipts kept for records of how money was spent for any given project or missionary?

When GFA illegally sent U.S. currency to India in student backpacks, students and staff were promised receipts. However, for the most part, these were not given to students and one staff member had to implore Yohannan and the U.S. leadership for receipts.

12. Who makes decisions that govern the activities of the mission?

Clearly, by Believers’ Church constitution, the decisions are made by K.P. Yohannan. According to former staffers, the same is true in the U.S., the board has very little role. One former board member Gayle Erwin left the board because he became convinced that Yohannan was withholding information from the board. Furthermore, Yohannan re-wrote a report Erwin penned because Yohannan perceived that the report portrayed GFA in a negative light.
More recently, Yohannan removed two board members from the board of GFA Canada after those board members began asking questions about GFA’s financial dealings.  The removal was contrary to the organization’s by-laws.
By his own standards, Yohannan’s current GFA fails badly and isn’t a good candidate for donations.
According to veteran missionary Billy Bray, the book should have listed him as first author since he wrote much of it. Read more about the authorship of Yohannan’s first three books here.
 
*Believers’ Church is the central organization in India. GFA in the U.S. sends donated funds to Believers’ Church to use them in India via GFA-India and other government registered charity entities.

Eric Metaxas and the Strange Hitlery Tweet

This so wrong on so many levels:


So many good replies:


Eine dummkopf.
Now Metaxas is up there with those folks who call Trump “Drumpf.”
Then I thought of Mark Noll’s sentence: “The scandal of the evangelical mind is that there is not much of an evangelical mind.”*
*Perhaps Metaxas was attempting a joke. In any case, it was a lame attempt. Given his support for David Barton, it is hard to tell when one can take him seriously.
Update: Now Metaxas says he was joking. Alan Noble (Christ and Pop Culture) provides the appropriate commentary.

K.P. Yohannan Criticizes Social Programs in His First Book But Spends Millions on Them in India

Will the real K.P. Yohannan please stand up?
In his first book Revolution in World Missions, K.P. Yohannan (through ghostwriter Bill Bray) criticized social programs such as hospitals and schools. However, Yohannan has directed massive amounts of donor money to build and purchase hospitals and schools in India. In the book RWM, Yohannan claims:

One issue involved one of the most far-reaching policy decisions I ever would make. For some years I had suffered deep pain over what appeared to be massive imbalance between our busyness with maintaining Christian institutions, like hospitals and schools, and the proclamation of the Gospel. Both in India and in my travels around Western countries, I constantly uncovered a preoccupation with so-called “ministry” activities operated by Christian workers, financed by church monies, but with little else to distinguish them as Christian.
Far too much of the resources of North American missions is spent on things not related to the primary goal of church planting.(p. 104-105, 2015 edition)

In contrast, Yohannan controls a massive empire of for profit businesses on behalf of himself and the church he runs, Believers’ Church. Twelve schools are listed on The Believers’ Church website, including a medical college and an engineering school. The flagship healthcare institution is his Believers’ Church Medical College and Hospital in the state of Kerala. In recent years, much donor money appears to have gone into the building or purchase of these institutions without the knowledge of American donors.
K.P. Yohannan – Patron
On the Believers’ Church Medical College and Hospital and the Caarmel Engineering School websites, K.P. Yohannan is described as the patron of these institutions.
The engineering school website proclaims Yohannan’s leadership:

Believers Church Caarmel Engineering College, established in 2002, is a leading self-financing private co-educational institution under the Caarmel Educational Trust owned and managed by the Believers Church headquartered at Thiruvalla, Kerala. Dr. K. P. Yohannan, Metropolitan, Believers Church, is the Chairman and Patron of the College. Fr. C. B. Williams is the Manager and Dr. Paul A. J is the Principal of the College.

In contrast to Yohannan’s claim that he doesn’t sit on the boards of any of the trusts in India, he is described as the Chairman and Patron on the school website. The school appears to be quite elaborate with excellent facilities. You can take a virtual tour of the campus online (link).
caarmel engineering
The Medical College and Hospital are quite new with the medical college just opening this year. Again, Yohannan is described as the patron:

Believers Church Medical College Hospital is a healthcare project of Believers Church. The Church is dynamically involved in various nation-building social and educational projects, healthcare initiatives, charitable activities, community development programs, rehabilitation projects and relief works. Dr. K.P. Yohannan, Metropolitan of Believers Church is the patron of the hospital and Dr. George Chandy is leading the project.

The facilities are extraordinary.
BelChurch Hosp
In his RWM book, Yohannan decries such “nation building” programs as causing him “deep pain.” He spends several pages indicating that his ministry will not focus on “social concerns.”

Because of this teaching, many churches and mission societies now are redirecting their limited outreach funds and personnel away from evangelism to something vaguely called “social concern.” Today the majority of Christian missionaries find themselves primarily involved in feeding the hungry, caring for the sick through hospitals, housing the homeless or other kinds of relief and development work. In extreme cases, among nonevangelicals, the logical direction of this thinking can lead to organizing guerrilla forces, planting terrorist bombs or less extreme activities like sponsoring dance and aerobic exercise classes. This is done in the name of Jesus and supposedly is based on His command to go into all the world and preach the Gospel to every creature. The mission of the Church, as defined by these humanists, can be almost anything except winning people to Christ and discipling them.
History already has taught us that this gospel—without the blood of Christ, conversion and the cross—is a total failure. In China and India we have had seven generations of this teaching, brought to us by the British missionaries in a slightly different form in the middle of the 19th-century. My people have watched the English hospitals and schools come and go without any noticeable effect on either our churches or society. (p. 109-110, 2015 edition)

 
I don’t know if GFA hosts dance and aerobics, but the group does sponsor a soccer team in Myanmar.
I have written before about GFA’s rubber plantation, but there are many more real estate holdings, according to Narada News in India. Then there is the matter of many tuition-funded residential schools which take in children of all faiths (e.g., the posh Believers Church Residential School).
In his book, Yohannan criticizes British missionaries but he has recreated the same infrastructure using donations from his affiliates around the world. Let me add that I personally have no problem with the work being done in these institutions. The problem is the deception of donors who read RWM and want to get behind a ministry which puts into practice what Yohannan preaches. For this and many reasons, donors should beware and be wise.

Gospel for Asia's Staff Exodus

In 2015, nearly 50 staff and families, many in key positions, left Gospel for Asia.
In a website project of some of the former staffers — Donor Be Wise — the exodus is described in detail.
staff-leaving-gospel-for-asia
This extreme turnover is a signal that something is very wrong at GFA. Regular readers of this blog will know that there is much wrong with the second largest mission group in the country.
The post concludes with just some of the concerns that have prompted GFA staff to seek work and ministry elsewhere.

The reasons so many staff left are many, yet one only has to read through some of the materials published to draw some conclusions as to the climate of the office leading up to the many public reports. Sadly some current staff have chosen not to read anything that has been published.

GFA’s board has not addressed this dire situation. Instead, their response has been to blame bloggers and admit vague inefficiencies. GFA has also spent loads of donor money on a campaign of public relations. For instance, in the face of the recent drought in India, GFA has spent a meager amount on supplying water while inflating their image at home.

A Problem I See with the DOE/DOJ Guidance on Transgender Students

At the outset, let me be clear that I believe transgender students should not be discriminated against when it comes to public accommodations. I have no problem with the Obama administration issuing guidance to schools about how the Departments of Justice and Education interpret the law regarding sex discrimination. While I don’t agree with all aspects of the DOJ/DOE documents (more on that below), I think schools benefit from knowledge of how the Departments interpret the law.
The guidance isn’t new law.*  The May 13 letter says:

ED and DOJ (the Departments) have determined that this letter is significant guidance. This guidance does not add requirements to applicable law, but provides information and examples to inform recipients about how the Departments evaluate whether covered entities are complying with their legal obligations.

While I don’t object to equal treatment under the law for transgender students, I question the DOE/DOJ on their interpretation of how a student should be regarded as transgender. According to the DOE/DOJ, no professional assessment of the student is required.

The Departments interpret Title IX to require that when a student or the student’s parent or guardian, as appropriate, notifies the school administration that the student will assert a gender identity that differs from previous representations or records, the school will begin treating the student consistent with the student’s gender identity. Under Title IX, there is no medical diagnosis or treatment requirement that students must meet as a prerequisite to being treated consistent with their gender identity.6  Because transgender students often are unable to obtain identification documents that reflect their gender identity (e.g., due to restrictions imposed by state or local law in their place of birth or residence),7 requiring students to produce such identification documents in order to treat them consistent with their gender identity may violate Title IX when doing so has the practical effect of limiting or denying students equal access to an educational program or activity.

All that is required for schools to treat students in keeping with their asserted gender identity is a student’s word (presumably for adult students) or a parent’s word (presumably for minors).
In my experience, parents often disagree over what is best for children. What is a school to do when one parent asserts a change in gender identity and the other doesn’t? In my clinical experience, I have seen just such cases. For instance, some parents interpret gender non-conforming interests as a signal that a child’s gender identity is different than what was assigned at birth. Such interpretation may not be in the child’s interest.
Evaluating the broad spectrum of children where gender identity is an issue often requires professional assistance. Particularly when children and teens are involved, getting competent help can be key in coming up with the best course of action in keeping with professional guidelines. To me, it makes sense for schools to require a supportive statement from a treating physician and mental health professional.
What is the basis for the DOE/DOJ claim?
As an authority (footnote #6) for the contention that schools can’t require a diagnosis, the DOE/DOJ letter uses a case of a transgender female employed by the Army who won an EEOC complaint alleging a civil rights violation in part because she was not allowed to use a common women’s bathroom. The Army’s defense involved a concern that the complainant had not fully physically transitioned from male to female. The EEOC ruled that an employer cannot require a medical procedure in order to deny civil rights to a transgender employee.
However, in that case, the complainant had legally changed her records and was legally female. While she had not had surgical reassignment, she had made significant steps toward transition. The facts of the case involve an adult and are much different than a school where a parent or student may not have consulted a professional.
Of course, students should not have to prove full reassignment to be treated fairly, but it seems to me that schools would be within their rights to require evidence from mental health professionals and physicians that accommodation would be appropriate. Schools regularly require professionals to provide opinions on lesser matters.
When the DOE/DOJ says “there is no medical diagnosis or treatment requirement that students must meet as a prerequisite to being treated consistent with their gender identity,” I think they go beyond the facts of the case they used as a basis for their interpretation. Perhaps there are other relevant cases, but the letter doesn’t list them.
Schools should be safe for all students, including transgender students. My concern is that this guidance will hamper schools in reacting for the good of all students on a case by case basis.
 
*When I first posted this article, I wrote that the DOE/DOJ letter wasn’t an edict. While I still don’t see it as heavy handed as some opponents do, I will concede that some school districts may experience it negatively. Furthermore, I removed that reference because I don’t want to distract from the main point of the post.
