Education Doesn't Work 2.0 - Freddie deBoer

Mobility of individual students in quantitative academic metrics relative to their peers over time is far lower than popularly believed. The children identified as the smart kids early in elementary school will, with surprising regularity, maintain that position throughout schooling.

The brute reality is that most kids slot themselves into academic ability bands early in life and stay there throughout schooling. We have a certain natural level of performance, gravitate towards it early on, and are likely to remain in that band relative to peers until our education ends.
