• There's a lot of teacher variation within the best schools. At one elite New York elementary school, just over half the teachers were above average, and the other half were average or below average.I am shocked! Shocked to find that only half of the teachers were above average!
I couldn't make this stuff up if I tried, folks.

ADDING: You know what? When a troll is right, a troll is right. That sentence isn't totally dumb: we do, in fact, have something to learn from the fact that there is a normal distribution of teacher VAM scores in an "elite" school. It's just completely the opposite of what the Trib is calling for in this piece. More later.
I have always claimed to be, and remain, a music teacher with an decent but amateur grasp of statistics and research methods, who is sick and tired of taking it from people who have no clue about what teachers do. This will no doubt not be the last time I mess up; but that doesn't mean I've been wrong before, and it doesn't mean I'm stopping.
And that sentence in the Trib is still funny. Sorry, it is.
