How to find out program acceptance rates?

[Loseric]

When looking at graduate programs' websites or the web, they (sometimes) list their acceptance rate. Unfortunately, this acceptance rate is for the whole program and not by individual programs. Specifically, I'm looking at a Master's in Education, which, of course, has many sub programs underneath it. I know some programs are more competitive than others, but I can't figure out a way to get those stats. How do you know how many students apply to your specific program? Second, how do you find out many students are enrolled in each program (another detail rarely listed on websites)? I'm trying to get a good idea of my chances here, and general acceptance rates aren't helping, unfortunately.

Lots of schools encourage applicants to email them with questions. Is this something I could ask admissions committees about and expect a truthful answer?
