When teachers leave the classroom for other professions, effective teachers earn more than less-effective ex-teachers. So says a study using value-added data by Matthew Chingos and Martin West of Harvard’s Program on Education Policy and Governance.
The Education Gadfly summarizes:
. . . among grade 4-8 teachers leaving for other professions, there was a positive relationship between a teacher’s increase in value-added math and reading student achievement and higher earnings outside of teaching. Admittedly, the sample was small, not randomly-selected, and only from one state, but the authors’ conclusion makes sense: “Although teaching is surely a unique endeavor requiring specialized skills, the same attributes that make for effective teachers also appear to be rewarded in the broader labor market.”
In the teaching profession, there is little relationship between effectiveness and earnings, the study finds. (No surprise.)
