Since teachers are so important to effective schools, it’s awfully useful to understand how it is that good schools end up with good teachers. Susanna Loeb and colleagues have a new paper that looks at the pattern of match-ups in the Miami-Dade County school district (the nation’s third largest). What they did was look at value added measures for individual teachers and for schools and checked what went with what.
- Among teachers who transfer schools, better schools attract better teachers even controlling for characteristics of the schools such as poverty rates. The data can’t distinguish whether these schools do a better job of selecting teachers or whether better teachers prefer better schools. The effect is somewhat stronger for math than for reading.
- Novice teachers are assigned lower achieving students. But highly effective schools do this much less.
- Teachers assigned to high performing schools increase their own performance faster than teachers assigned to not so effective schools.
