Goldhaber has published multiple studies and briefs trying to get at the importance of teachers’ performance in the classroom and how that performance ought to be calculated. He says that the development of teacher quality gaps isn’t particularly surprising, since states and school boards tend to view teacher job assignments as fungible — even if it’s actually much harder to teach in a high-poverty district or school than a more affluent one.
“You’d expect that there would be teacher quality gaps because there’s very little differentiation between teacher salaries within a school system,” he told The 74 in an interview. “Teachers don’t have quality measures stamped on their forehead, but you could imagine that the better teachers would have some advantages in that kind of labor market, and would get the choice teacher assignments.”
