Shortly after my research synthesis Visible Learning (2009) was published, many of my colleagues were unhappy with the finding relating to the overall effect of school leaders. Across the 55,000 studies, which represented a quarter of a billion students, the average effect size of all influences was .40, whereas the effect size for leaders was a few notches below, at .36.

Another answer to 'why class size effect sizes' are low, is pretty obvious when you look at the tables above. Hattie derives his lowest effect size of 0.09 (incorrectly). Then w hen you average very small effect sizes from class sizes of 40 down to 30 with large effect sizes of 20 down to 15 you get a low average.

In order to try to figure out what the 1.44 effect size is based on, I tried to go back to the studies that Hattie used to get to that effect size. Hattie analyzed 900+ meta-studies of educational programs and procedures, and came up with an “effect size” for each of 195 “influences” on learning (138 in 2009 and 150 in 2012).
