The Supplemental Educational Services (SES) policy, under No Child Left Behind, requires perennially underperforming Title I schools to offer free academic tutoring to eligible students. Previous research on SES had conflicted results on whether or not the programs were valuable. A meta-analysis of findings from 44 external evaluations of district operated SES in Ohio showed positive effects on the academic performance of at-risk students who receive tutoring in reading and mathematics. When compared with the average annual gain in effect size from nationally normed tests, SES participants fell 0.69 standard deviations below. The subgroup analysis demonstrated greater effects in students who received services in reading and students in elementary and middle schools and lower grade levels.
