DC charter schools have a lot to be proud of.
Among the most impressive accomplishments is the steadily increasing proficiency rates of their students.
This comes year after year, despite charter student counts increasing by 8 to 10 percent each year and charters serving a lower-income population than the city as a whole.
Indeed the data I watch most closely as an indicator of how successfully the Public Charter School Board is doing its work is this:
DC CAS information for 2012 was released a few months ago and showed that overall charter proficiency continued to rise, albeit modestly, for the sixth year in a row. We highlighted this in our press release at the time.
Now the DC Schools Fund has released a new set of analysis on DC CAS performance, both for charter schools and for DCPS. It highlights the growth in both sectors, and is worth looking at.
My favorite chart from the analysis is this one:
We still have a long way to go, but it's heartening to see the progress.
