2009 NAEP scores are in!

It's hard to know what the NAEP scores mean for students with disabilities--since we don't have a handle on the exclusion rates and accommodations policies that differ from town to town and state to state. Hopefully, once NAGB's new and improved (!) policy is implemented these test results will be more consistent and easier to interpret. At the end of the day, we would expect the scores of students with disabilities to be lower than those of their general education peers, due to their disabilities, but I'm not a statistician and can't estimate what the different ranges should be.
