This should surprise nobody. From the BBC: "Students taking online courses from prestigious US universities will be able to take final exams in a global network of invigilated test centres." The online tests will be invigilated and the centres wll authenticate the identities of test-takers. This - rather than any story about selling content or data - is the the monetization strategy end-game for MOOCs (though no doubt with the rise of test centres will come the rise of private tutoring). For the record, I predicted this development in my 1998 paper The Future of Online Learning, here.
