Does anyone out there have a child who received accommodations in college specific to a BPD diagnosis? If so, what were they?
Can't say I've heard of that on the boards here, though that doesn't mean it hasn't happened.
Some pwBPD have additional MH/brain issues going on -- autism, Asperger's, ADD, ADHD, learning disability, dyslexia, etc.
Has your D been assessed for any of those? She still has a few months left in HS so it is possible your district may be required to assess upon your request -- could be worth looking into. If that leads to SPED services and/ or an IEP/504 plan, those plans will spell out the accommodations your public school must provide. That in turn could be reference material if your D goes off to college -- while I don't think colleges are required to continue a 504 or IEP, your D could bring that to an admissions or inclusion staff member and say "this was my plan in HS, can we work with this here?"
You can also check out wrightslaw.com which is a reputable site for the law surrounding disability in education. They at least focus on grades thru 12th, you'll have to see if they have info for college age students too.
Hope that gives you a starting point;
