Our old school (near Boston) used to have a lovely enrichment program for spelling and math for 4th, 5th, and 6th grades with wonderful (college-level) teachers. The year my DS was in 5th grade, the school explicitly (and proudly! in the principal's newsletter to parents!) redirected the funding for remedial education so that kids at the 20th percentile could have a shot at passing the MCAS (the state's annual NCLB test).
