What is the impact of small group tutoring on student math achievement?

Tutor Trust: Affordable Primary Tuition: Evaluation report and executive summary November 2018

The purpose of this study is the examination of low-cost interventions to improve the performance of disadvantaged students. The intervention was designed to improve the performance of students by providing small-group tutoring sessions. The selected students who participated in tutoring received 12 hours of additional instruction for 12 weeks. The students were tutored in groups of three by trained university students and recent graduates. Students in the control schools continued with normal teaching. The research found that children who received tutoring progressed more in math compared to children in control schools (effect size = +0.19). Students eligible for free reduced school meals benefited even more with an 0.25 effect size.
