Here's the answer I (finally) got from the local diagnostician:

"...we don’t reevaluate students once they are identified as gifted. Many times the scores will decline and then they do not meet the criteria. If you want testing for other reasons (suspected disability) then that could be done but I am not sure we would redo the cognitive test. Since you are attending a school in Albuquerque it is the responsibility of APS to complete the evaluation. Additional information from you and the teachers would help to determine what testing would need to be completed..."

As I said before, he was so young before and had not been diagnosed/medicated for ADHD at the time.

Thoughts? Should I push to get the test done again?
