Meta-analysis of 40 studies (8 articles, 28 MA theses, 4 PhD theses) published 2000–2014, each with pretest–posttest control data, analyzed with the treatment effect method and a random effects model. The article reports "the overall weighted effect size was 1.68" (REM; 95% CI 1.36–2.00 per Table 1).

"According to the quantitative findings, following the analysis of academic achievement scores from 40 studies with respect to REM, the overall weighted effect size was 1.68. Thus, it can be stated that creative drama had a considerable effect on academic achievement."
