Charter or District in Milwaukee?

(Guest Post by Matthew Ladner)

Last year John Witte, Pat Wolf, Alicia Dean and Devin Carlson found evidence of significantly stronger academic gains for charter school students over district students in Milwaukee using the state data. This got me to wondering what the 2011 Trial Urban NAEP scores would look like between MPS and Milwaukee charter schools. Now, mind you that this chart doesn’t control for much, only comparing FRL eligible students in the charters and the districts. That’s okay with me, as Witte, Wolf, Dean and Carlson have admirably performed that task on three years of data with a promise of a fourth year in 2012 report. Also there is always at least a bit of sampling error with NAEP, yadda yadda ectera.

Do the NAEP tests tell the same broad story as the Witte et. al study? Judge for yourself:

 Those look like differences likely to survive the introduction of a whole bunch of control variables.
