The National Alliance for Public Charter Schools, my old stomping grounds, has just done us all a major service and itself proud.
Back in my day, the "Charter Dashboard" was just a handful of interesting data points about the state of the charter school sector. Well now, just days before their annual confab, they reintroduce it as a big and thorough report with just about all of the important descriptive statistics on charter schools you could want. And they have an online version, too!
Whether you're an ivory-tower researcher, hands-in-the-dirt practitioner, or just an active education observer, this document will have something for you. ????Definitely check it out; it's really quite impressive.
(As far as dashboards go, unless you are in the 13-to-19 demo, it's the best thing going by far.)...
