> someone that has enthusiasm and a skill set could surely pick that up as they go. Sounds like the early days of Teach For America where enthusiasm will mostly get you between a few days and few years of service. I think it’s pretty complicated to measure the effect of teachers in lots of context, let alone with respect to educational attainment. The exception is at the intervention level: Teachers who learned X technique for improving Y skill improved Y skill at a higher occurrence than teachers who did not learn X technique. Even for interventions you need to develop understanding of childhood/adolescent cognitive and emotional development in order to communicate effectively. Maybe enthusiasm gets you there organically through experience, maybe you quit. Certainly in an otherwise pristine learning environment, enthusiasm for learning itself is a baseline desirable trait.
