This project will explore whether regions in Texas are producing enough math and science teachers (MAST) to meet demand; factors leading to MAST attrition including opportunity wages of external labor markets; and whether historically underserved students have equitable access to high-quality MAST. Previous research in this area is limited by the inability to link data on teacher labor markets to external non-teacher labor markets in the private sector. Analyses utilize a statewide longitudinal student-level dataset covering all students in Texas over a 20-year period.
