The clinical teaching experience is one of the most important components of teacher preparation. Prior observational research has found that more effective mentors and schools with better professional climates are associated with better preparation for teacher candidates. We test these findings using an experimental assignment of teacher…

There is growing interest in using measures of teacher applicant quality to improve hiring decisions, but the statistical properties of such measures are not well understood. We use unique data on structured ratings solicited from the references of teacher applicants to explore the dimensionality of measures of teacher applicant quality and the…

We evaluate the predictive validity of the Massachusetts Candidate Assessment of Performance (CAP), a practice-based assessment of teaching skills that is typically taken during a candidate's student teaching placement and is a requirement for teacher preparation program completion in Massachusetts. We find that candidates' performance on the CAP…

Improving the skill set of new teachers is a potentially important policy lever to increase student achievement. There are, however, doubts about the extent to which teacher education programs contribute to the development of teachers' skills. In this paper, we describe findings from an experiment designed to test whether one aspect of teacher…

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations-- middle school math, ninth-grade algebra and geometry, and ninth-grade biology--and find evidence that a teacher's basic skills test scores are modestly predictive of…

As part of Washington State's efforts to ensure and improve the quality of the teacher workforce, the Professional Educator Standards Board (PESB), with assistance from Educational Testing Services (ETS), has recently introduced a new, evidence-based assessment of teachers called the ProTeach Portfolio. The development of ProTeach was mandated by…

This digest examines research on indicators of teacher quality. While research on the value of a teacher's advanced degree is mixed, all studies suggest that teachers with degrees in subjects different from the subjects they teach have little impact on students. There is no strong consensus about the value of pedagogical preparation for teachers,…
