NEPC Review: Addressing Teacher Shortages: Practical Ideas for the Pandemic and Beyond (TNTP, February 2022)

Ben DeGrow
Addressing Teacher Shortages: Practical Ideas for the Pandemic and Beyond

In light of the pandemic which has likely resulted in rampant teacher absences and widespread teacher shortages, a TNTP report offers leaders clearly articulated employment goals and numerous recommendations for short- and long-term staffing plans. Although reliable evidence on the extent of teacher shortages is mixed, the report does provide leaders confronting staffing issues with some helpful questions and potentially useful recommendations. Despite these positive elements, however, the report has several research-related weaknesses. Accordingly, while school and district leaders may find in this report some useful ideas to consider, they should read additional research and reports to independently determine whether recommendations of interest are evidence-based and how local context might affect implementation.

Making Next Year Count: Equity in School Accountability (Bellwether Education Partners, Summer 2020)

Making Next Year Count: Equity in School Accountability
Making Next Year Count: Equity in School Accountability (Bellwether Education Partners, Summer 2020)

Bellwether Education Partners’ four-part series on accountability reviews the historical roots, theory of change, and impact on student outcomes of school accountability systems, as well as the effect of COVID-related school closures on testing and accountability. The series notes that state accountability systems have not improved student achievement or closed achievement gaps over the last decade. Despite this conclusion, the series insists state testing and accountability systems must be reinstated in 2020-21 and must focus on schools with the lowest performance levels. In addition to this perplexing inconsistency, the reports are problematic for a number of reasons. Policymakers are advised to ignore this series and access more nuanced reviews and recommendations regarding school accountability in the coming years.

NEPC Review: Time to Change Course: Reclaiming the Potential of Texas Charter Schools (ExcelinEd and Texas Public Policy Foundation, June 2018)

Adam Jones & Amanda List
Time to Change Course: Reclaiming the Potential of Texas Charter Schools

A policy paper from ExcelinEd and Texas Public Policy Foundation examines the charter-school authorizing process in Texas. After surveying past Texas authorizing policies, the study claims Texas had been a leader in creating high-performing charter schools and that a low barrier of entry into the market was a contributing factor to this success. The study then contends that a 2013 legislative policy change has made the authorization process too restrictive, thus reducing the number of applicants and stifling innovation. The paper concludes with recommendations to create an easier authorization process to increase the number of charters granted and thereby to foster innovation. While the report is billed as a case study, it does not employ case study methodology. Moreover, the report fails to review or cite relevant research; it instead relies on unsubstantiated claims, anecdotes, misleading statements, and even demonstrably false statements to advance a particular viewpoint. In short, this paper is an ideological advocacy paper masquerading as a case study. Policymakers would be well advised to skip this paper and look for a more evidence-based review of the Texas charter authorizing process.

NEPC Review: Preparing Principals to Raise Student Achievement: Implementation and Effects of the New Leaders Program in Ten Districts (RAND Corporation, May 2014)

Preparing Principals to Raise Student Achievement: Implementation and Effects of the New Leaders Program in Ten Districts

RAND’s recent evaluation attempts to determine the New Leaders principal preparation program’s impact on student test scores, concluding that New Leader principals are slightly more effective, albeit only for certain grade levels, subject areas, and districts. But the study’s overall conclusion is problematic for at least eight reasons. First, the effect sizes are quite small—less than 2 percentile points in the lower grades, where the data allow for more reliable analyses—and the study’s results are more mixed than its bottom-line conclusion would suggest. Indeed, most of the results find no statistically significant impact of New Leader principals on student test scores, and there were nearly as many negative findings as positive ones. Also, the study fails to acknowledge the extant research on the limitations of the study’s value-added model (VAM) with school fixed effects approach. Additionally, problems include a failure to control for the same variables in each VAM, for peer effects, or for the scores of student stayers and leavers. The study also failed to discuss the potential impact of changes in the way student achievement was measured in the districts or to explore how the distribution of school-level scores might have influenced the results. Yet in the face of these problems and limitations, this study implies—incorrectly—that it can offer a valid causal determination that the New Leaders principals had a small positive effect on student test scores.

Review of Evaluation of Teach for America in Texas Schools

Herbert M. Turner, David Goodman, Eishi Adachi, Jessica Brite, & Lauren E. Decker
Evaluation of Teach for America in Texas Schools

A new study funded by Teach for America (TFA) attempts to identify the effect of TFA teachers and alumni on student test scores. The report, by Edvance Research, matched schools and students within those schools on both demographic and achievement characteristics. It then used the matched student data in a multi-level regression analysis to estimate the effect of being taught by a TFA teacher on mathematics and reading test scores for two groups of students: those in grades 4 and 5 and those in grades 6 through 8. Of the eight comparisons performed, three were statistically significant: mathematics and reading scores of middle-level students taught by TFA alumni and mathematics scores for middle-level students taught by novice TFA teachers. While the findings were large enough to be relevant to policymakers, numerous issues with the sample construction, matching procedures, and statistical analyses lead us to conclude the outcomes cannot be attributed to TFA teachers. Furthermore, these issues make it likely that the actual size of the TFA teacher effects differ than what is found in the report. Thus, the report should not be accepted as solid evidence of any TFA teacher or TFA alumni effect.
