This article measures the achievement impacts of 41 Knowledge Is Power Program (KIPP) charter middle schools nationwide and found consistently positive and statistically significant test-score effects in reading, math, science, and social studies.

This working paper discusses a new analysis, using data from Florida and Chicago, suggesting that charter high schools are not only increasing postsecondary educational attainment but may also boost students' long-run earnings.

Mathematica's rigorous evaluation of the Teacher Incentive Fund (TIF) will estimate the impact of performance pay on student achievement, as well as educators' attitudes toward and awareness of TIF and their mobility and recruitment. This report provides contextual background on performance pay...

This working paper illustrates—theoretically and through simulations—that the Rothstein falsification test is not definitive in indicating bias in value-added model estimates of current teacher contributions to student learning.

The authors conducted a randomized controlled trial, which showed that during the first year of a teacher’s career, students of teachers in comprehensive induction programs scored no better on achievement tests than students of teachers in their school’s usual induction support. A...

This paper examines the program's effect on student achievement across the state, using longitudinal data on district math and reading scores for 524 Missouri school districts over a nine-year period. The estimated effects of the Career Ladder program range from small positive effects to no...

This paper looks at findings from the first national randomized study of the impacts of charter schools on student achievement.

In the past two decades, the number of states offering alternative certification routes for teachers increased from a handful to 45. Some estimates suggest that a third of any given year's newly hired teachers come through these routes. However, teacher training programs vary widely in their...
