It's very rare that if you meet TS requirements you're not getting the Q (if you're placed in a position where it's needed as more than likely you are already SCI cleared). In fact if you are denied for Q it likely means you're losing your TS too. There are exceptions but I would argue they're not the norm.
Either way, we have propensity to over classify things in the government and that's a whole other argument.
