In this response, we first show that Simpson's proposed analysis answers a different and less interesting question than ours. We then justify the choice of prior for our Bayes factors calculations, but we also demonstrate that the substantive conclusions of our article are not substantially affected by varying this choice.

Grow Your Own (GYO) programs are designed to recruit high school students, paraeducators, community organizers and parents, and/or career changers from the local community to join the educator workforce. When considering the nontraditional teacher pools that may enter the profession through GYO programs, commonly held assumptions about who…

A recent paper uses Bayes factors to argue a large minority of rigorous, large-scale education RCTs are "uninformative." The definition of "uninformative" depends on the authors' hypothesis choices for calculating Bayes factors. These arguably overadjust for effect size inflation and involve a fixed prior distribution,…

An analysis was conducted of the What Works Clearinghouse (WWC) research evidence base on the effectiveness of replicable education interventions. Most interventions were found to have little or no support from technically adequate research studies, and intervention effect sizes were of questionable magnitude to meet education policy goals. These…

Over the last decade, teacher evaluation has moved onto center stage in efforts to strengthen schooling. In this article, we address the question of whether focusing on this administrative process is likely to accomplish what reformers hope. We answer that question by examining the available evidence, both direct and indirect. We deepen the…

In the 2012-2013 school year, Chicago Public Schools unveiled its new teacher evaluation system in all of its almost 600 schools. This study draws on 32 interviews from a random sample of teachers and 2 years of survey data from more than 12,000 teachers per year to measure their perceptions of the clarity, practicality, and cost of the new…

School shootings have generated great public concern and fostered a widespread impression that schools are unsafe for many students; this article counters those misapprehensions by examining empirical evidence of school and community violence trends and reviewing evidence on best practices for preventing school shootings. Many of the school safety…

How many students repeat a grade each year? How do retention rates vary across states and over time? Despite extensive research on the predictors and consequences of grade retention, there is no systematic way to quantify state-level retention rates; even national estimates rely on imperfect proxy measures. We present a conceptually simple…

The use of eligibility for a free lunch as a measure of a student's socioeconomic status continues to be a fixture of quantitative education research. Despite its popularity, it is unclear that education researchers are familiar with what student eligibility for a free lunch does (and does not) represent. The authors examine the National School…

Answers criticisms by Mary Anne Bunda, Ernest House, and Mary Kennedy. Discusses, among other issues, legal authorization for the use of higher quality evaluation designs and the use of evaluation research results. (GC)

Six deficits of this model are discussed: disparity in proponent prowess, fallible arbiters, excessive confidence in the model's potency, difficulties in framing the proposition in a manner amenable to adversary resolution, "a cat's-paw for biased decision makers," and, excessive costs. (Author/JM)

Presents a case study of how the review and clearance procedures are operating for evaluation instruments used in collecting information in connection with studies for the U.S. Office of Education. The review procedures are defective: They consume too much time. They are very costly. The results are unproductive. (Author/JM)

Describes a $50 million research and development program begun by the National Board for Professional Teaching Standards (NBPTS) to develop assessment instruments and prototypes for its teacher certification system. NBPTS's mission is to develop a national voluntary certification system for experienced teachers. (FMW)

Explores issues in evaluating exemplary programs, including the measurement of the degree to which the program is exemplary or promising. Suggests that comparison (control) group analysis can mislead researchers about the effectiveness of a program and suggests the use of gain scores to identify exemplary programs. (SLD)

Education researchers, practitioners, and policymakers alike are committed to identifying interventions that teach students more effectively. Increased emphasis on evaluation and accountability has increased desire for sound evaluations of these interventions; and at the same time, school-level data have become increasingly available. This article…
