Heather Vogell and Hannah Fresques published an important piece of investigative journalism that appears in ProPublica and USA Today about a new twist on the charter scamming in Florida. The scam is the result of Jeb Bush’s high-stakes accountability system, which incentivizes schools to get rid of low-performing students in order to maintain their letter grades and rankings.

Here is the shorthand: School officials nationwide dodge accountability ratings by steering low achievers to alternative programs. In Orlando, Florida, the nation’s tenth-largest district, thousands of students who leave alternative charters run by a for-profit company aren’t counted as dropouts. Is this why nationwide graduation rates are going up? Is this what Arne Duncan claimed credit for?

It begins like this:

TUCKED AMONG POSH GATED COMMUNITIES, and meticulously landscaped shopping centers, Olympia High School in Orlando offers more than two dozen Advanced Placement courses, even more afterschool clubs, and an array of sports from bowling to water polo. U.S. News and World Report ranked it among the nation’s top 1,000 high schools last year. Big letters painted in brown on one campus building urge its more than 3,000 students to “Finish Strong.”

Olympia’s success in recent years, however, has been linked to another, quite different school five miles away. Last school year, 137 students assigned to Olympia’s attendance zone instead attended Sunshine High, a charter alternative school run by a for-profit company. Sunshine stands a few doors down from a tobacco shop and a liquor store in a strip mall. It offers no sports teams and few extra-curricular activities.

Sunshine’s 455 students — more than 85 percent of whom are black or Hispanic — sit for four hours a day in front of computers with little or no live teaching. One former student said he was left to himself to goof off or cheat on tests by looking up answers on the internet. A current student said he was robbed near the strip mall’s parking lot, twice.

Sunshine takes in cast-offs from Olympia and other Orlando high schools in a mutually beneficial arrangement. Olympia keeps its graduation rate above 90 percent — and its rating an “A” under Florida’s all-important grading system for schools — partly by shipping its worst achievers to Sunshine. Sunshine collects enough school district money to cover costs and pay its management firm, Accelerated Learning Solutions (ALS), a more than $1.5 million-a-year “management fee,” 2015 financial records show — more than what the school spends on instruction.

But students lose out, a ProPublica investigation found. Once enrolled at Sunshine, hundreds of them exit quickly with no degree and limited prospects. The departures expose a practice in which officials in the nation’s tenth-largest school district have for years quietly funneled thousands of disadvantaged students — some say against their wishes — into alternative charter schools that allow them to disappear without counting as dropouts.

Keep reading. It is a shocking story, especially in light of the fact that Betsy DeVos is so impressed with Florida’s “success” that she wants to use it as a model for the nation. She surely can’t use her home state of Michigan as a model in light of its precipitous decline in national rankings on NAEP. What Florida and Michigan have in common, however, are for-profit charter chains, where the owners profit handsomely but the kids do not.
