Beginning next month, the massive open online course provider Udacity will cut the first O from the acronym and only offer MOCs. Founder Sebastian Thrun, whose "pivot " last year shifted the company's focus to corporate training, in a blog post announced Udacity will stop issuing free course completion certificates  on May 16. The course materials will still be available on the website for independent study, but in order to earn a certificate, students need to verify their identity. That track is currently available for about $150 a month.
"Discontinuing the 'free' certificates has been one of the most difficult decisions we've made," Thrun wrote. "We know that many of our hardworking students can’t afford to pay for classes. At the same time, we cannot hope that our certificates will ever carry great value, if we don’t make this change."
