Hi there,
Programs can be put on probation and given a period of time to correct their deficiencies. Some are able to make the grade and some are not. It is not a good idea to rank a program that is on probation as you could wind up not being able to finish residency or even worse, not eligible to sit for boards.
Go to that ACGME website and ask questions of the programs that you interview at. The program directors should be very forthcoming about any deficiencies and knowledgable as to when the next site visit should be. If not, steer clear.
