In this study, we estimated the relationship between two popular measures of teacher effectiveness--teachers' value-added model (VAM) estimates, represented in this study via median growth percentiles (MGPs), and teachers' observational scores, derived from the TAP System for Teacher and Student Advancement. We examined the relationship between…

Previous reports suggest that administrators rarely dismiss low-performing teachers despite the changing policy landscape allowing them to do so. This brief uses survey data from Tennessee to investigate the underlying reasons explaining administrators' decisions to retain low-performing teachers. The presented analysis suggests that…

In this study, we investigated the factor structure underlying the TAP System for Teacher and Student Advancement used across the nation for increased teacher-level accountability purposes. We found evidence of poor fit based on the factor structure posited and found large correlations among dimensions, suggesting one-to-two factors with one…

Papay (2011) noticed that teacher value-added measures (VAMs) from a statistical model using the most common pre/post testing timeframe--current-year spring relative to previous spring (SS)--are essentially unrelated to those same teachers' VAMs when instead using next-fall relative to current-fall (FF). This is concerning since this choice--made…

This quantitative study investigated the relationship between teacher dispositions, subject content knowledge, pedagogical content knowledge, and reasons that school principals recommend non-renewal of teachers' contracts. Nearly 2,000 school principals in 13 states completed an emailed survey. In deciding whether to non-renew a teacher contract,…

Teacher evaluation is at the center of current education policy reform. Most evaluation systems rely at least in part on principals' assessments of teachers, and their discretionary judgments carry substantial weight. However, we know relatively little about what they value when determining evaluations and high stakes personnel decisions. The…

What is effective teaching? It is not enough to say "I know it when I see it"--not when we are expecting so much more from students and teachers than in the past. To help teachers achieve greater success with their students we need new and better ways to identify and develop effective teaching. The Measures of Effective Teaching (MET)…

Teacher preparation programs (TPPs) are where prospective teachers gain a foundation of knowledge about pedagogy and subject matter, as well as early exposure to practical classroom experience. Although competence in teaching, as in all professions, is shaped significantly by on-the-job experiences and continuous learning, the programs that…
