RT Journal Article SR Electronic T1 Licensure Tests and Teacher Supply JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0324-13465R2 DO 10.3368/jhr.0324-13465R2 A1 Orellana, Alexis A1 Winters, Marcus A. YR 2025 UL http://jhr.uwpress.org/content/early/2025/07/03/jhr.0324-13465R2.abstract AB 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.
