It seems the evidence is weaker than I thought and we have no strong evidence that subject matter expertise is any more helpful than an education degree. Likewise experience may not help as we can’t rule out greater texture in a school leading to getting better classes so the teachers look better. Great schools and great teachers exist. We have no idea how to make either.

Yes.
