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.

Ideally, nonexperimental methods that aim to replicate the results of rigorous randomized experiments focus on the intent to treat (ITT) experimental impact estimate, the most causally rigorous measure. This working paper develops a new replication approach that facilitates testing...

Mathematica provided technical assistance in developing and estimating VAMs for use in Phase 1 of the pilot.

This REL Mid-Atlantic study looks at eight districts that have been using alternative measures for teacher evaluations or performance-related compensation systems.

Teacher value-added models (VAMs) must isolate teachers’ contributions to student achievement to be valid. Well-known VAMs use different specifications, however, leaving policymakers with little clear guidance for constructing a valid model.

This paper uses individual student-level data from Ohio–which permits a wide range of organizations to authorize charter schools—to examine the relationship between type of authorizer and charter-school effectiveness, as measured by students’ achievement trajectories.

This report describes The Equity Project (TEP) charter school’s instructional and personnel strategies, examines the characteristics and attrition rates of TEP students, and measures TEP’s impacts on student achievement during the school’s first four years of operation.

This report summarizes research findings and implementation practices for teacher and principal value-added models (VAM) as a first step in the Team Pennsylvania Foundation’s pilot project to inform the development of a full, statewide model evaluation system. The report selected 21...
