Now let’s look at the percentages of students who ‘passed’ the DC-CAS in 2011 – that is, who were ‘proficient’ or ‘advanced’ according to the testing company.
First, reading pass rates by school in the regular public schools:
As you can see from the graph, at a majority (actually, 74 schools, or about 64% of the total) of the regular DC public schools, the pass rate in reading is under 45%. There are four schools where the pass rate is over 90% (they are, in order, School Without Walls, Banneker SHS, Janney, and Mann. Here are the DC schools with pass rates between 80% and 90%: McKinley Tech, Lafayette, Key, Murch, Ellington, Deal, Oyster-Adams Bilingual, and Hyde-Addison. And there are three with pass rates under 10%: Stanton, Garfield, and Eastern.
Here is the corresponding graph for the charter schools:
It’s interesting to me that there are NO charter schools this year with 90% or better pass rates in reading, and also NONE with a pass rate lower than 10%. In fact, there is only one charter school with a pass rate in reading greater than 80%: Washington Latin. On the other hand, there are only 31 out of the 73 charter schools (42%) with pass rates under 45%.
Now, the pass rates in math for the regular public schools:
and next the percentages of charter school students ‘passing’ the DC-CAS in math for 2011:
