The US equivalent is shorter, but the final evaluation is actually running a giant exercise with, air, land, sea and special force assets. They don't do a lot of the theoretical content we do; instead they learn by doing, with actual mentoring and oversight.
Our looks at the theory of leadership, and some other very concrete issues as an academic issue, and then maybe some of it will stick (if you do jobs relevant to that kind of thing). No actual practical portion, which doesn't make sense when the actual subjects are very concrete and practical issues like leadership and operational planning.
No one coming out of JCSP is going to be able to do actual staff planning off the bat unless they have previous experience as a junior officer or Major/LCdr. There will still be a significant learning period if you go into a staff job to learn the specifics there, and a lot of people will go to JCSP and never do that kind of work.
And if you read the syllabus, people will be doing that kind of work at the two ringer and two and half already without JCSP, and your prep for those is a posting message, and, if you are lucky, a turnover. A huge swathes of the CAF is also doing critical things like financial planning, project managements and logistic/technical support that isn't covered at all in JCSP, which is why the CAF already has a sponsored PG program.
Lot of empire building at CFC on this one, and really no justifiable reason for it to be physically located in Toronto, where everyone is required to do a cost move to the most expensive city in Canada (or go on IR to a place that isn't close to the majority of the bases). If it was at least located in the NCR area that would make sense, as a lot of people are posted there following the course anyway to do staff jobs anyway.
Given the financial costs of running the school, the salary of the students, and the loss of a year of time doing jobs, I don't see the bang for the buck here. At least with sponsored PGs it's tied directly to a specific job so that knowledge is put to use immediately afterwards.
