This article investigates the association between studying with a contract teacher and a student's academic outcomes, using data from five Francophone African countries for two grade levels and two subjects. Based on this analysis, the evidence for or against this form of teacher hiring is inconclusive. The results indicate that these…

While instructional time is viewed as crucial to learning, little is known about the effectiveness of reducing absences relative to increasing the number of school days. In this regard, this paper jointly estimates the effect of absences and length of the school calendar on test score performance. Using administrative data from North Carolina…

Relying on the results of the achievement tests in mathematics, science, native language (Hebrew/Arabic) and English, administered to 1430 5th-grade co-educational classes in Israel, this study examines the between-class variability of the within-class mean score gender differences and its class and school correlates. The four main results of the…

This paper reports the results of a descriptive study on the use of a technology-enhanced formative assessment system called Accelerated Math (AM) for ELLs and their native-English-speaking (NES) peers. It was comprised of analyses of an extant database of 18,549 students, including 2,057 ELLs, from grades 1 through 8 across 30 U.S. states. These…
