How fair is the PMF really? Schools like Bridges and Creative Minds with higher populations of special needs and other schools with higher at-risk don't seem to get the same credit on the PMF as schools with lower populations of SPED or at-risk kids. This isn't just sour grapes (ok, maybe a little). But it is what seems apparent to me in looking at OSSE's averages for PARCC growth for different groups.

PARCC Growth Percentiles, Math, Reading
All Students, 50, 50
Econ Disadvantaged, 47, 47
Special Education, 44, 40
Black, 46, 46
White, 65, 63

If a school serving SPED kids has average growth for their students, they'd earn 10.5 points on the growth section of the PMF.
A school serving Black kids with average growth for their students, would earn 14 points.
A school serving White kids with average growth would earn 29.7 points.

The PMF calculator is online and you can enter the numbers yourself and see what I mean. https://www.dcpcsb.org/performance-management-framework-pmf/performance-management-framework-pmf-calculators

I don't know the ins and outs of how it works.  But the focus on growth, as opposed to final outcomes, is intended to do EXACTLY what you want it to- focus on how an actual school impacts the kids attending, no matter who they are.  The idea is to level the assessment playing field so that if you have a bunch of already smart kids getting 80s on the test, you don't score as well as a school which saw a kid go from 40 to 60.

So I while I don't know exactly how the scoring works, I have confidence that the issue you are worried about has been addressed and "baked in" to the PMF.  That's exactly why they make growth such a big component of the overall score.

Not true. The PMF isn't showing the school's contribution to performance. If my white kid has growth of 55, which is 10 points lower than his subgroup, the school gets more points for that kid than it does for a black kid that has growth of 51, which is 5 points higher than his subgroup. The school is growing the black kid faster and isn't serving the white kid as well. [/quote]
