There's a thread about test scores at various high schools on the previous posting about the Promise. Those comments start on July 4th and list test scores for the PPS high schools.
On the Pure Reform website, this page has links to charts of performance from 2004 onward:
The first link there compares changes in PPS versus state results as a whole. In a nutshell, any gains in the PPS have been mirrored by similar gains statewide. Whatever we're doing here isn't outdoing what everyone else is doing -- our scores don't seem to be improving any more than the statewide scores, despite all the changes.
There are a couple of things to remember as you read the test scores. HS students are only tested in 11th grade; younger students are tested in all grades 3-8. To compare schools solely on their scores is problematic, you should also consider demographics, magnet programs, etc.
This link at A+ Schools http://www.aplusschools.org/eq_reports_09.shtml gets you to the two page listings for each school. Those pages break out some of the information, like % of kids getting free or reduced lunch and scores by race, IEP, and by income status. There need to be 40 kids in a category for it to be broken out in the charts. For instance, in CAPA's 11th grade in 2009, there weren't enough kids with IEPs for their scores to be reported separately.
