A math program, adapted for use in the after-school setting, resulted in 49 more hours of math instruction during the school year (30 percent more) for math program students than for their counterparts. The math program students scored 2.8 scaled points higher on a test of math achievement at the end of one year, an 8.5 percent difference in achievement growth. The impacts did not vary significantly for students in different grades or with different prior levels of achievement. Nor did the math program students and their counterparts differ significantly on other in-school behavior. For the full evaluation report visit:
