We've gone 15 rounds for each of my kids on ADHD. In our case, it was a matter of addressing the needs of the child, with no clear evidence (that very boarderline data) of ADHD/ADD-i.

How old is he and how old is he compared to his peers?

Is this a change from last year to this year?

What are the disabilities that put him in the category of 2e? Are they being well managed?
