Charter School Growth

Yesterday, I wrote about some key questions facing the charter school movement. I starting thinking about how important these questions are in terms of the structure of our public education system. Here is what I dug up.

Data for 2009-2010 and 2010-2011 were unavailable. The percentage of total schools that are classified as charter schools is increasing by about .29% per year. This means that in 2011-2012, charters are projected to be about 5.63% of all operational schools (assuming a linear trend). This is a relatively small proportion of the total, but certainly more than just a drop in the bucket. And this proportion is growing larger each year.

 
In fact, charter schools have more than doubled since 2000, whereas the total number of operational schools has grown by about 10% over the same time frame. This impressive growth shows that charter schools have gained traction. Serious work needs to be done to analyze the charter model and how it can successfully be scaled up.
