The
Multiple Acceptance Report, which is released and updated daily in February, allows
only schools that have accepted you, where else you are holding acceptances. They will see this
only after they have accepted you. It does not show to anything to schools where you have not been accepted, nor does it show to any schools at any time where else you may have applied to and are awaiting actions. This can be used by schools to estimate how many spots they may fill and how many acceptances over the number of seats they should offer.
The
National Acceptance Report, which is released starting May 1st (after action deadline of April 30th) allows
every school to see
all applicants with acceptance or matriculated action. If I am not mistaken, it does not indicate waitlisted status as that is a school specific standard/action. So if you are on a waitlist in mid-May, a school can see if you have acceptances else where prior to offering you a spot.
