Here’s a factoid that I hadn’t known. Public school students are quite a bit more likely to attend school in a large school district than was true in the past. I’ve made a little chart showing the percentage of students in districts with over 10,000 pupils.
In 1979, 46 percent of students were in large districts. Today (well 2011, which is the latest data), the number has risen to 55 percent. At the same time, the number of very small school districts–those with fewer than 300 kids–has fallen by a third.
Much of this may just be a consequence of population growth. To some extent we’d expect all districts to have more students in the past. It turns out that there’s something more than that going on, as the number of school districts has fallen 15 percent over the same period.
I’m pretty sure that closing very small districts is mostly a good thing. They’re probably too small to be efficient. But is it a good idea to have more students in mega-districts? Or is there a sweet spot somewhere in-between tiny and mega?
