Dear Dr. Glass As you may know, the Education Endowment Foundation in England, in order to help with interpreting effect sizes in education, has suggested to teachers that an effect size of one standard deviation is approximately equal to one year’s progress, and they cite the following from page 103 of your 1981 book ‘Meta-analysis in education’ in support:
It is also known, as an empirical—not definitional—fact that the standard deviation of most achievement tests in elementary school is 1.0 grade-equivalent units; hence the effect size of one year’s instruction at the elementary school level is about +1, for example,I asked one of your co-authors, Barry McGaw (whom I know well) if he could recall where this figure came from and he could not, hence this email to you.The reason I ask is that for many of the tests currently in use in CONTINUE READING:
∆ = (4.0 - 3.0) / 1.0 = +1.

A Los Angeles Times analysis of the 75 lowest-performing schools on the state’s English language arts test, based on California’s Common Core standards, illustrates the depth of the reading problem. Seven out of 10 third-graders in these schools did not meet the standards, according to state data from 2018 and 2019. The schools have about double the English learners of other elementary schools, and more than 90% of students at those schools qualify for free or reduced-price lunch — a poverty indicator.
