Google thinks it has found a way to make its learning stick. It has become more exacting about when it offers classes and to whom. It uses employee reviews of managers—similar to the instructor reviews that college students fill out at the end of a semester—to suggest courses to managers. Ever data-obsessed, Google uses statistics gathered from current and former employees to recommend certain courses to managers at different points in their career, say after a move to a new city or joining a new team. - danblank
