Evaluators of education interventions are increasingly designing studies to detect impacts much smaller than the 0.20 standard deviations that Cohen (1988) characterized as "small."

The SASS is a periodic integrated system of sample surveys conducted by the National Center for Education Statistics (NCES) that produces sampling variances…

The 1998 High School Transcript Study (HSTS) provides the U.S. Department of Education and other policymakers about current course offerings and students' course taking patterns.
