I only called the Mason MC/MPA office. I'm a Mason applicant and I told her as such. Therefore, I guess she gave me Mason applicant's status. It's highly possible that non-Mason applicants could be in a different pool.
I just spoke to HKS. This lady says that EVERYONE that has been admitted to the MC/MPA has already been notified via email. All others will receive their rejections or Waitlist status end-of-business tomorrow. So I guess if you haven't heard from them by now, unfortunately you might not get in.
Last year's decision(s) for MC/MPA came out on 3/25/2010 a Thur.My rejection came at 3.25pm PST via email. I'm thinking this year they have more applications than they had last year...or fewer manpower to go thru' them.
If you are a US citizen or a citizen from developed countries, you will not be able to apply via the Mason Program, you will have to apply thru the MC/MPA route. Mason program is reserved for non-US citizens mainly from developing countries and the former Soviet Union.
