|NCEE 2022003||Enhancing the Generalizability of Impact Studies in Education
This guide will help researchers design and implement impact studies in education so that the findings are more generalizable to the study’s target population. Guidance is provided on key steps that researchers can take, including defining the target population, selecting a sample of schools—and replacement schools, when needed—managing school recruitment, assessing, and adjusting for differences between the sample and target population, and reporting information on the generalizability of the study findings.
