I'm looking for a non-profit, regionally accredited, fully online M.Ed. program in Adult Education. I'm new to the forums, so I apologize if this has been hashed out.
A good list to get you started is the GetEducated list: Best Buy Online Masters of Education | Ratings & Rankings | GetEducated.com Ranked by cost, these are all RA schools, there are several with adult ed concentrations on the list. (Note that tuition fees may have increased since the time that list was put together.) One school that isn't on the GetEducated list but does have a concentration in adult education is Central Michigan University: Master of Arts degree in Education from CMU Off-Campus Programs That is a "Master of Arts in Education" degree, not sure if the MEd nomenclature is a deal-breaker or not.
