Unequal education

I've only been recently learning about Portland's open transfer policies. Interesting and troubling.
PPS Equity, a local resource for the community concerned with inequities in the Portland Public School system, posted these facts today. As usual, it's hard to argue with the numbers.

Average teacher experience (in years) in Portland Public Schools: 14.2

Number of schools with average teacher experience of 12 years or fewer: 17

Number of these schools in the Jefferson, Madison Marshall and Roosevelt clusters: 15

Number of these schools in the Cleveland, Grant, Lincoln and Wilson clusters: 0

Number of schools with average teacher experience of 16 years or more: 21

Number of these schools in the Jefferson, Madison, Marshall and Roosevelt clusters: 5

Number of these schools in the Cleveland, Grant, Lincoln and Wilson clusters: 15

And here is the rest of it.
