Measuring Teachers' Effectiveness: A Report from Phase 3 of Pennsylvania's Pilot of the Framework for Teaching

In this report we analyzed data on two measures of teacher performance—one (the Framework for Teaching, or FFT) is based largely on classroom observations, and the other (value-added measures, or VAM) is based on student test scores. The data we analyzed cover 6,676 teachers from 269 districts in the state of Pennsylvania. Although FFT scores are overwhelmingly concentrated in the top performance categories, the positive correlations with VAM suggest that the FFT provides some meaningful differentiation and captures aspects of teacher skills related to student achievement growth.
