WWC synthesis of two studies (Humphrey et al., 2018, Hodder Group Reading Test, 2,504 students; Weis et al., 2015, NWEA Reading, 949 students); the summary reports an average effect size of 0.07 that is not statistically significant, described as "uncertain effects 0.07 +3 No (p=0.30)". The report states the research does not support claims of improved literacy achievement.

"Summary for literacy achievement: uncertain effects 0.07 +3 No (p=0.30)"
