National interest is growing in Integrated Student Support (ISS) interventions, which offer schools systematic ways to reduce barriers to learning. The present study exploits the random component embedded within the school assignment system of a large urban school district to estimate the effect of schools providing ISS on student academic…

Propensity score matching was used to compare third-grade test scores in English language arts, mathematics, science, and social studies for children who had and had not participated in Georgia's Pre-K 4 years earlier. After matching, each group included 46,262 children (mean age 8.36 years in third grade). In all subject areas, children who had…

We estimate relative achievement effects of the four most commonly adopted elementary mathematics textbooks in the fall of 2008 and fall of 2009 in California. Our findings indicate that one book, Houghton Mifflin's "California Math," is more effective than the other three, raising student achievement by 0.05 to 0.08 student-level…

Identifying which early mathematics skills have the largest effects on later mathematics achievement has important implications. However, regression-based estimates often rely on untested assumptions: (a) Scores on different mathematics skills reflect unique constructs, and (b) other factors affecting early and later mathematics achievement are…
