Yes and no.

When you look at populations, it averages out, but there are definitely 10x teachers out there. It’s more of a function of teacher+student combination. The problem is actually more about the structure of schools that limits what great teachers can do.

I’m sure there are studies out there - I’m also extremely skeptical that studies can adequately measure variation in teaching performance (I come from a background in sports / circus, where scientists are always 10-20 years behind the state of the art understanding of the actual practitioners)

(I think it’s kind of like with coding - anyone can write a CRUD app, and anyone can teach basic arithmetic. But certain teaching tasks require very skilled teachers to work)
