Licensure Tests and Teacher Supply

Abstract

We apply a sharp regression discontinuity design to administrative data from Connecticut to investigate the impact of failing the first attempt at a licensure test on teacher supply. We find deterrent effects from failing both a basic skills test required to enter an educator preparation program (Praxis I) and a subject-matter test used for ultimate certification (Praxis II). Failing Praxis II especially deters those seeking endorsement to teach within the shortage areas of STEM and special education. Failing Praxis II disproportionately pushes out relatively effective potential teachers and those who would have taught in schools with relatively smaller proportions of students who are Black or Hispanic, learning English, and eligible for subsidized lunch.
