At Public School 234 in TriBeCa, where children routinely alight for school from luxury cars, roughly one-third of the teachers’ ratings were above average, one-third average and one-third below average.I mean, except in Lake Wobegon, isn't this what average means (no pun intended)? It's the perfect distribution. If you fired the bottom third, wouldn't one-third still be below average?
The Times story continues:
At Public School 87 on the Upper West Side, where waiting lists for kindergarten spots stretch to stomach-turning lengths, just over half the ratings were above average. The other half were average or below average on measure, based on student test scores.
Amazing! Half above and half below average. How do they do it?
If this trend continues, we can only assume that in New York City (and in the universe as a whole), half the teachers will be above average and half below. And if these ratings are based on test scores, that must hold true for students as well.
