Worldwide market for online tutoring is estimated to be in the region of $12 billion.This is something I've been seeing more of, especially in the high school and college markets where tutoring has been more common. Online models allow for better matching of students to tutors and more cost effective models. One interesting model is social homework help provided by Cramster. It allows students to get help on specific textbook problems and to ask questions that are answered by experts.
I've not heard as much about this in corporate settings. Is coaching following this pattern? Moving online? Finding lower cost options?
