I've had a positive experience so far in the MU Psyd program. The first few quarters were somewhat stressful, but after that it's been pretty flexible. The faculty are pretty accessible and the class sizes are mostly small. I would caution people considering MU that Meridian is not APA accredited but they are WASC accredited. Apparently they don't plan to pursue APA accreditation, which may be important depending on what state you are in.
Also some of the course content can be pretty intense and personal. So you should be prepared for that! At least in the Psychology program which I guess is to be expected.
I would recommend for those looking for a challenging online psychology program.
Faculty all seem to be qualified and have expertise. I haven't taken many electives yet though. Some of the textbooks are old. Other students have mentioned that as well.
