The U.S. Department of Education ruled invalid Pennsylvania’s effort to inflate the scores of charter schools by treating them as local school districts.

Here is a description of what state education secretary Ron Tomalis tried to do.

The state’s charter-friendly education department had decided to treat charters as districts for purposes of NCLB scores, which made their performance look better. But US DOE said that was a no-go and all the charter scores must be recomputed.

Interesting that the announcement was made on the day before the long holiday weekend, which meant that someone decided to bury it.
