Dear vamsi.emperor,
On mba.com, you have to look at each school individually for that information. It will only be there if the school has entered it, so some schools might not have updated their profiles. Another option to get a good cross section for this type of data is to pull the rankings from different publications as most offer up a chart with all of this type of data on the schools included in the ranking. It will give you a nice snapshot of these types of statistics on 30-50 programs.
Regards,
Lisa
