An anonymous reader shares a report: In the last five years, dozens of schools have popped up offering an unusual promise: Even humanities graduates can learn how to code in a few months and join the high-paying digital economy. Students and their hopeful parents shelled out as much as $26,000 seeking to jump-start a career. But the coding boot-camp field now faces a sobering moment, as two large schools have announced plans to shut down this year -- despite backing by major for-profit education companies, Kaplan and the Apollo Education Group, the parent of the University of Phoenix. The closings are a sign that years of heady growth led to a boot-camp glut, and that the field could be in the early stages of a shakeout. [...] One of the casualties, Dev Bootcamp, was a pioneer. It started in San Francisco in 2012 and grew to six schools with more than 3,000 graduates. Only three years ago, Kaplan, the biggest supplier of test-preparation courses, bought Dev Bootcamp and pledged bold expansion. It is now closing at the end of the year. Also closing is The Iron Yard, a boot camp that was founded in Greenville, S.C., in 2013 and swiftly spread to 15 campuses, from Las Vegas to Washington, D.C. Its main financial backer is the Apollo Education Group. Since 2013, the number of boot camp schools in the United States has tripled to more than 90, and the number of graduates will reach nearly 23,000 in 2017, a tenfold jump from 2013, according to Course Report, which tracks the industry.
