Sorry to be late to this, and I hope not to just foment trouble, but to the OP: I can't see this being a wise choice as a stepping stone MA.
I'm not particularly familiar with the program's graduates (aside from one very underwhelming English instructor I had in high school) but I would point to a few readily apparent shortcomings:
1. No thesis or comprehensive exams (someone will correct me if I'm wrong here).
2. No TAships/RAships, usually an important part of the grad experience
3. Not much funding (see 2; incidentally, at this point, the program seems to resemble an expensive book club rather than a graduate program)
4. That not many people seem to have heard of this program does not bode well for "serious" lit. circles, especially in this application/job market
5. Geared towards high school teachers rather than scholars
In my estimation, if one wanted to be a high school teacher, there are a host of one year M.A.T. programs that would serve him or her better (e.g., Brown, various R1 publics), and if one wanted to be a scholar, there are numerous MA programs that would situate one well, both in the US and Canada, or one could enter a PhD program.
This program seems best to serve individuals who already hold teacher licensure and want the prestige of an MA from a "good school" or will receive a nominal pay increase. Or it seems a very enjoyable way for an affluent individual passionate about book to spend his or her summers.
