"Best And Worst Teachers Can Be ID'd Early"

Sarah Sparks at Edweek writes up an interesting new study.

New teachers become much more effective with a few years of classroom experience, but a working paper by a team of researchers suggests the most—and least—effective elementary teachers show their colors at the very start of their careers.

Hmm. Interesting how top quintile teachers maxed out in Year 2. Thoughts?

I can imagine a version where Year 2 teachers keep burning midnight oil at the same max capacity as Year 1, with big increases in efficiency over Year 1. So spike.

Then in Years 3 and beyond, they shift some hours towards personal sustainability. You know, "extras" like sleeping 8 hours a night, eating food while not grading papers, hitting the gym once in a while, calling Mom on a regular basis. Maybe even dating.
