For our upcoming graduates, we know at least 3 months out who they are. Once we have identified who they are we tracking (via excel spreadsheet) when the one-on-one exit interview is scheduled, if the students missed, and then when it is completed. We require (audit and compliance checks) that 100% of our graduates have an exit interview prior to completing their finals. We even have a individuals whose primary job is to make sure that the exit is completed and completed timely.
