TL;DR: In this article, the effects of various types of education and training on the productivity of teachers in promoting student achievement were studied. But they did not find a consistent relationship between formal professional development training and teacher productivity, and they found no evidence that teachers' pre-service training or college entrance exam scores are related to productivity.

TL;DR: This paper explored the policies that helped to reduce the achievement gap before 1990, the effects of the subsequent shift toward accountability, and what can be learned from past successes to guide the future development of accountability systems.

TL;DR: This paper found that teacher turnover differs most from other professions in the greater prevalence of turnover among older workers, likely reflecting earlier retirement, and found some evidence that the relatively high ratio of pensions tosalaries in teaching partially explains this behavior.

TL;DR: In this paper, a randomized experiment is used to estimate the impact of a private need-based grant program on college persistence and degree completion among students from low-income families attending 13 public universities across Wisconsin.

TL;DR: This work considers six value-added models that encompass most commonly estimated specifications and test many of the central assumptions required to derive each of the value- added models from an underlying structural cumulative achievement model and reject nearly all of them.
