An other more direct issue is Goodhart’s law: if teacher compensation is linked to a specific metric, then that metric is what you’ll get. If the metric is test scores, then you’ll see:

- teaching to the test rather than educating

- trying to get rid of left behind, slow, or difficult students (already an issue for generations in test-oriented private institutions — as opposed to the more remedial “last chance” ones)

- ignoring the groups which have the lowest odds of contributing to the metric (which groups it is depends on the weighting / averaging between pupils)
