I summarize these various concerns as they relate to issues of internal validity, measurement, and external validity. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher preparation practices published in peer-reviewed journals between 2002 2019. Although I find that very few studies address issues of internal validity, measurement, and external validity, I highlight some innovative approaches and present a checklist of considerations to assist future researchers in designing more rigorous impact evaluations UR - https://doi.org/10.3102/00346543231174413 ER -
