Honestly after a lot of research I don’t think there is a huge difference for a trans kid among colleges as long as you stay in a solid blue state. (If you don’t then yes do very careful diligence on the school, the town and the state). The big differentiators that hit a bit differently are school size (my kid didn’t want to be one of a small handful of trans kids at any school even the most welcoming) and whether the school is close to a city (my kid wanted access to a big urban center for more access to queer and/or alternative music, art, theater etc). (Yes I am sure nightlife too, let a mom stay in denial). Of course all trans kids are different and those may not be important issues for others. Schools in or near DC, Baltimore, Chicago, Boston, NYC, Seattle, LA, or San Francisco seemed to us to be the best and safest fit.
