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.

This In Focus brief provides a snapshot of the study and findings.

At the request of Pittsburgh Public Schools and the Pittsburgh Federation of Teachers, Mathematica has developed value-added models that aim to estimate the contributions of individual teachers and schools to the achievement of their students.

This study describes how eight early-adopting school districts are using two types of alternative measures for assessing teacher effectiveness: value-added models that use the results of end-of-course assessments or commercially available tests in statistical growth models instead of typical...

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...

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...
