This study investigated the effects of Supplemental Educational Services on student achievement in reading and math. A meta-analysis was conducted to investigate the relationship between student achievement gains in reading and participation in SES. Six studies were used in the meta-analysis with a total of 395 participants. The combined weighted effect size correlation was r = 0.48. A meta-analysis was conducted to investigate the student achievement gains in math. Two studies were used in the meta-analysis, with a total of 136 participants. Their combined weighted effect size correlation was r = 0.04. The magnitude of this effect size correlation is trivial, indicating that participation in math SES produces little effect; however, the effect size correlation associated with reading SES suggests a large effect on learning outcomes in the content area of reading.
