Our district flags kids who score over the 95th percentile for math or reading and sends home permission forms for a cognitive ability test. If they do well on the ability test (98th percentile on one or more sections) then they are put into cluster groups the next year. See if your district has a G/T coordinator or at least ask the classroom teacher how kids are chosen for G/T services. Put your foot down and insist he doesn't need any remedial reading programs. Now you have data to back it up.
