Positive Effects of Comprehensive Teacher Induction
Today, Mathematica Policy Research, Inc. released the final report of its IES/U.S Department of Education -funded randomized controlled trial (RCT) of comprehensive teacher induction. It shows a statistically significant and sizeable impact on student achievement in mathematics (0.20 standard deviations) and reading (0.11 standard deviations) of third-year teachers who received two years of robust induction support. That's the equivalent of moving students from the 50th to 54th percentile in reading achievement and from the 50th to 58th percentile in math achievement. As a basis of comparison, I note that in 2004, Mathematica conducted a RCT of Teach for America (TFA). In that study , it compared the gains in reading and math achievement made by students randomly assigned to TFA teachers or other teachers in the same school. The results showed that, on average, students with TFA teachers raised their mathematics test scores by 0.15 standard deviations (versus 0.20 standard d...
