Ensuring Fair and Reliable Measures of Effective Teaching: Culminating Findings from the MET Project's Three-Year Study


"This non-technical research brief for policymakers and practitioners summarizes recent analyses from the Measures of Effective Teaching (MET) project on identifying effective teaching while accounting for differences among teachers' students, on combining measures into composites, and on assuring reliable classroom observations.

Readers who wish to explore the technical aspects of these analyses may go to to find the three companion research reports: Have We Identified Effective Teachers? by Thomas J. Kane, Daniel F. McCaffrey, Trey Miller, and Douglas O. Staiger; A Composite Estimator of Effective Teaching by Kata Mihaly, Daniel F. McCaffrey, Douglas O. Staiger, and J.R. Lockwood; and The Reliability of Classroom Observations by School Personnel by Andrew D. Ho and Thomas J. Kane."
