The Class Size and Pupil-Adult Ratios project aimed to provide, for the first time in the UK, a full analysis of the educational effects of class size and adult-child ratio differences over the whole of reception, KS1 and KS2.

In the KS2 part of the study (7-11 years), attention focused more specifically on the role and effects of TAs in classrooms.

This research brief focuses on selected aspects of the data collected, and seeks to present results in a way which provides a coherent account of the role, deployment and effectiveness of TAs in classrooms.
