This is a bit a vent and a bit of a PSA. I am currently doing a Master's program through GMU, but I have taken 5 grad school classes through UVA (one distance learning, and 3 at the satellite campus in Falls Church). UVA appeared to only have a certificate program in the area I'm pursuing, which was why I chose GMU. However upon further research, I now realize I could have done the the complete Master's through UVA. While I'm too far into my program to make the switch, I wanted to put some observations out there in case it can help other teachers deciding between local programs.
Price: GMU costs at least 1/3 more than UVA for in-service teachers. At first glance, UVA is only a bit cheaper, but they give a much bigger discount for public school teachers.
Summer Options: GMU's summer is an accelerated May/June semester, which is also one of the busiest times of the year for teachers. UVA has tons of 'real' summer classes online and through their satellite campus. My program doesn't offer any summer options that occur in July/August.
Course Work: While both equally rigorous, GMU seems to be more geared toward pre-service teachers in their course work. UVA's classes seem to have more application types of projects, whereas GMU seems to love their 20-25 page research papers.
Field Experience requirements: The program I'm in requires 20 hours of field experience for each class. This is great and important for pre-service teachers. While not a big deal for in-service teachers to simply fill out the log and get a coworker to sign it, it's cited as the reason they can't provide "real" summer classes (July/August-when teachers aren't stressed out and can devote more time to professional learning).
Of course, some of this could be program specific such as the Field Experience requirements or the dearth of summer options. Prices are also different if you are part of a cohort. I just thought I would share this as I know many teachers think GMU is the best local option, and GMU recruits heavily in local school districts.
