Are there online resources for finding information on M.S. programs that fit my criteria, without having to go through every school's website?
The most useful I found (which also helped me finding one for me) is Find a masters.

It does let you select a country of your choice, provides a summary of program where courses list, research focus and other things important are mentioned.

It also lets you filter by program type (Dip, Cert or degree), by study plan (part time, full time etc) and more.

Lastly, it also provides a link to university website so you can go there easily for complete details if you like the description.
