Advanced Degrees Rarely Improve Teaching

Analysis of multiple administrative‑data and twin studies suggests teacher Master's and other advanced degrees have little to no causal effect on student achievement once you control for teacher, student, and school fixed characteristics. The main measurable effects in several studies are small, inconsistent, or limited to nonacademic outcomes (e.g., absenteeism), calling into question degree‑based pay premiums and licensure rules. — If true, states and districts should reconsider degree pay bumps, licensure requirements, and union contract language and instead redirect resources toward hiring practices and in‑class supports that show measurable gains.
