My son has gone to this school for almost two years. He is currently in the 2nd grade. Sellers consistently produces high scores on the standardized tests (relative to similar schools statewide). Their AR program offers differentiated reading levels somewhat. At the beginning of the 2nd grade my son was tested and shown to be reading at the 5th grade level. His assigned AR books were all around level 2.8 or so. Lately they have been around the 3.4 level which is what he was doing last year. So far I have not seen any differentiated math programs. For two years I have watched my son do math homework that is far below his ability. Maybe that will change in the 3rd grade when he is in the GATE program. Maybe it won't change. The "No child left behind" policy seems to yield results that no child will be allowed to excel.
