I finally got together some data comparing regular DC public schools, the charter schools, and both systems combined, using the enrollment figure available to me at the NCLB-OSSE-DCPS website for spring 2007 through spring 2010. I made the assumption in all cases that the number of regular public school students, added to the number of charter school students, should give the total number of publicly-funded students in each and every single category. If this assumption is wrong, then so is my data.
First, let’s look at the total fraction of the student population in the publicly-funded schools that is in the regular public schools and the charter schools.
As you can see, the fraction of publicly-funded DC students who are enrolled in the charter schools has been growing pretty steadily, though the growth from ’09 to ’10 was smaller than earlier. Will it ever happen that there are more kids in DC charter schools than in regular DC public schools? I don’t know; watch this blog for the next decade or so to find out.
Next, let’s look at the fraction of the entire tested population that is black (i.e., African-American). In this graph and table, there are three categories: all publicly-funded DC schools, all regular public schools, and all charter schools.
As you can see, the fraction of black students in the tested grades in all publicly-funded DC schools has dropped a bit (from 85% to about 82%),, while the fraction of black students in the charter schools has remained almost level (going from 90% to 89% isn’t much of a change). However, I think the drop in the fraction of black students in the regular public schools is fairly significant. It dropped from about 84% to about 78%, at least in the tested grades (which do NOT include Pre-K, Kindergarten, nor grades 1, 2, 9, 11, or 12).
Next, let’s look at the fraction of Hispanic students in all three types of schools.
As you can see, the fraction of Hispanic students in all publicly-funded DC schools has gone up a bit, from about 9% to about 11% in the past few years. The fraction of Hispanic students in the charter schools not only started lower (about 7%), but it has gone up by very little (to a tad over 8%). The fraction of Hispanic students in the regular public schools has been, and continues to be, higher, reaching a rate of nearly one student in 8 by 2010.
