I'm at a 4-7 facility and there are plenty of us that want to advance to an 8-10 facility (and some that want to go even higher), but because we haven't received people from the academy, or previous experience people, we don't have anyone to fill our shoes if we leave so we're stuck and can't release anyone. It's ridiculous. My opinion, keep filling the 4-7s from the academy so the rest of us that have certified at a bottom level facility can advance our careers. When people say, "yes, it's possible you'll be stuck at that facility your whole career.." something is seriously wrong with the system. Not to mention, some of us had academy lists with all 5's and 6's so we weren't even given the opportunity to start higher up like others. I think it would be a shame to make 4-7 facility people have to go to an 8-10 before an 11 or 12. If they want to make that leap, they should be permitted to. Just my 2 cents.
