We all can check the "At Board List" on MPTE. But the OCS class dates and rosters (I believe) can only be checked if you have ENTRS or CETARS access. I don't have access to either of those, but my Chief does. My chief said she'll be checking for me daily once January hits. I think Career Counselors, LCPO's, people in "senior" leadership, and anyone with certain collaterals only have access to those.
EDIT: I just tried accessing both. I have access to CETARS. In CETARS there is a link to access ENTRS. I tried accessing ENTRS and the page said for me to "REQUEST ACCESS." If I were you (and you don't have access to ENTRS), I'd just get cool with someone in your leadership to check for you daily. My Chief and Training Officer are rooting for me and are on top of it and checking for me daily.
