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.

This paper explores how the design features of curriculum materials might influence potential opportunities to learn and student outcomes through a comparative, documentary analysis of four mathematics curricula commonly used in the United States.

Read the final report from a large-scale, rigorous study examining how four math curricula affect achievement across two years—from first through second grades. The curricula were (1) Investigations in Number, Data, and Space; (2) Math Expressions; (3) Saxon Math; and (4) Scott...

This appendix provides the details that underlie the analyses reported in the evaluation brief, “After Two Years, Three Elementary Math Curricula Outperform a Fourth.†The details are organized in six sections: Study Curricula and Design (Section A), Data Collection (Section B),...

This report summarizes the evidence on measures of student achievement growth used in teacher evaluation that do not rely on traditional annual state assessments, and that instead use commercially available assessments, locally developed common assessments, and teacher-developed student learning...
