My ADHD/ASD son went to the GT/LD program of MCPS, which in our case was just the next cluster over at North Bethesda MS and Walter Johnson HS. He also had private tutors for math and writing, since those were his weak points. The middle school GT/LD program had a special resource classroom instead of one elective with a great SN teacher who understood the kids (by and large all ASD/ADHD). In high school he didn't really need it anymore.
He did as well as he could - no environment would have been perfect and I truly believe NB and WJ did a great job accommodating his needs. Yes, there was some bullying in 6th, and we taught him to snark back to make it stop. He transitioned to a 504 in 12th and went to a T50 college.
