She was 8 when diagnosed.
We chose to homeschool for anxiety reasons (she is selectively mute) but also school reasons. ADHD wasn't a factor in the decision, but her general mental well being was. The anxiety was tied up in the academics or lack of.
The ADHD is more managed now she is at home, plus all the secondary aspects of it can be monitored, e.g. she forgot to eat and drink at school, so we can now stop the after school food meltdowns, we can exercise her more etc.
The only other testings she's had were the WPPSI at age 5, she still scored very high but with a big discrepancy between PSI, we were testing for issues with verbal and receptive language (for the mutism) so didn't look at why there were the variations in scores. She's also done Ravens (as part of an ADHD study)but the only reported score was 99+.
