The idea is to randomly assign the students to teachers. Sometimes teachers will get students who will never reach grade level, and sometimes students who will effortlessly achieve. By being random, it evens the opportunity out.

That sounds horrible. Right now, schools try to give each teacher an even number of high-performing, average, low-performing, and “difficult” kids. But the numbers are so small it’s hard.

An average sounds like a shitty, shitty system. Imagine finding out your kid is in a classroom with every low-performing and difficult kid in the grade just because it was random.

The concept sounds good in theory, but I think it's going to be nigh unworkable in practice. The NCLB/high-stakes testing era exposed many problems with tying educator pay to student outcomes -- chief among them that student outcomes didn't improve.

As I recall they had the teachers themselves graded those tests, so naturally they cheated.
