Seems obvious that charter school teachers work longer hours and are less experienced. How else can charter school management companies make a profit?

Charter school teachers tend to have fewer years of experience, and work longer hours than their counterparts in public, non-charter schools, a new analysis suggests.

Yet by another measure—the hiring of teachers from "highly selective" colleges—both charters and traditional public schools lag well behind the private school norm.

Many of those findings are consistent with past research, notes the author of the paper, Marisa Cannata of Vanderbilt University, whose work is included as part of a newly published book, Exploring the School Choice Universe: Evidence and Recommendations. But the analysis provides fresh insights into who goes to work in public and private sector schools, and what kinds of conditions they encounter when they get there.

Some are even going to crazy lengths to maximize profits, as Stephen Dyer discovers

There is an amazing story out of Florida now posted here and here that delineates just how outrageously high K-12, Inc. schools' student-teacher ratios are. K-12, Inc. runs Ohio Virtual Academy, with educates about 10,000 Ohio students.

Just a few tidbits. The heads of schools are told that they should have the following ratios in the following grades:

K-8: 60-72:1
9-12: 225-275:1

That's right. K-12, Inc. thinks it's a good idea to have kindergartners in classes as high as 72:1 and high school kids in 275:1 classes.

We really don't need research anymore, just look at any of these companies 10k financial filings.
