Lambda, an online school, wants to teach nursing

Unlike most online courses, Lambda does not charge students up front to attend (though admissions are competitive) and online tuition is live and interactive, not recorded. The school only starts getting paid back for its services after its students have landed a job which pays them more than $50,000 a year, something Lambda expends significant energy to help them do. After nursing, Lambda plans to work its way down the list of professions with the biggest job shortages.
