Does value-added modeling (VAM) demonstrate the importance of teachers to student outcomes? The authors clarify the primary questions raised by VAM for measuring teacher effects, review the most important recent applications of VAM, and discuss a variety of statistical and measurement issues that might affect the validity of VAM inferences. The authors identify numerous possible sources of error and bias in teacher effects and recommend a number of steps for future research into these potential errors.read more

Teacher Quality in Educational Production: Tracking, Decay, and Student Achievement
TL;DR: This paper developed falsification tests for three widely used value added modeling (VAM) specifications based on the idea that future teachers cannot influence students' past achievement and found that each of the VAMs' exclusion restrictions are dramatically viola ted.

Estimating Teacher Impacts on Student Achievement: An Experimental Evaluation
TL;DR: The authors used a random-assignment experiment in Los Angeles Unified School District to evaluate various non-experimental methods for estimating teacher effects on student test scores and found that teacher effects faded out by roughly 50 percent per year in the two years following teacher assignment.

How Context Matters in High-Need Schools: The Effects of Teachers’ Working Conditions on Their Professional Satisfaction and Their Students’ Achievement
TL;DR: In this article, the authors recognize the challenges posed by teacher turnover, and they pay a price when new teachers leave the profession after only 2 or 3 years in the profession and return to teach again.

Teacher Preparation and Student Achievement
TL;DR: In this article, the effects of features of teachers' preparation on teachers' value-added to student test score performance in math and English Language Arts were investigated. And they found that preparation directly linked to practice appears to benefit teachers in their first year.

The central role of the propensity score in observational studies for causal effects
TL;DR: The authors discusses the central role of propensity scores and balancing scores in the analysis of observational studies and shows that adjustment for the scalar propensity score is sufficient to remove bias due to all observed covariates.

Estimating causal effects of treatments in randomized and nonrandomized studies.
TL;DR: A discussion of matching, randomization, random sampling, and other methods of controlling extraneous variation is presented in this paper, where the objective is to specify the benefits of randomization in estimating causal effects of treatments.
