Worse, it seems that many of the schools touted as "successes" actually have fewer of these children with special needs in their student bodies:
The schools with bars pointing downward have fewer of the kids with special needs; the ones with upward pointing bars have more of those kids. You can see there's a wide variation; you can also see that schools like Robert Treat, Learning Community, and Elysian - which charter cheerleaders point to as "successes" - serve a different population than the schools at the right of the graph.
Now, I've been following the Christie reform circus for a while; it struck me that I had never heard of some of these schools, while others are very well known. And part of the reason is that our governor loves to have photo-ops at schools, but only at certain, select ones.
Which ones? Well, to illustrate, I modified the professor's graph a little:
Here's what I found with the Google machine:
Learning Community: 8/31/09
Trenton Community: 2/24/11
Robert Treat: 1/18/11
If you know of more, tell me in the comments, and I'll change the graph. At first glance, it would appear that the best way to get the governor to pay a visit to your charter is to figure out a way to keep as many poor, special ed, and non-English-speaking kids out of your school as possible.
I don't know about you, but I think Christie needs to spend some time at the schools to the right. Even the middle would be helpful.
