More Class Size Action

There were getting to be too many updates on last week's post on charter schools in Harlem so I decided to do an entirely new post based on something Julie posted over on the School of Blog. She writes, with regard to class size data:

I just want to point out that in at least one case, these data are a little suspect. One school, listed as having opened in 2000, is compared to its co-locating school from school year 1999-2000 on. That school, however, did not move into that building until school year 2004-05. Comparing school year 2003-04 (pre-move) to 05-06, in only two grades did average class size go up at the non-charter public school, one of which went up by only half a student. In all other cases class size went down.

The point is, these charts are weird and don't account for all the many reasons class size can go up or down in a school.

Thanks, Julie.
