The Supplemental Educational Services (SES) policy, under No Child Left Behind, requires underperforming Title I schools to offer academic tutoring to eligible students. A meta-analysis of findings from 44 external evaluations of district operated SES programs in Ohio showed that scores increased on the academic performance of at-risk students. When compared with an 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.
