TCLEOSE (Texas) requires yearly re-qualification. My agency requires it quarterly. We have numerical scoring, but I believe TCLEOSE only gets a "pass/fail" report. I honestly can't remember if they get the actual score or not. Ours is scored on a scale up to 250 with 180 required to pass.
Every agency has their small portion of folks that don't do too well. They pass, but just barely. By and large we all do pretty well, but do a LOT of tac training in addition to the quarterly quals.
And the lower scorers get ribbed with to their face, a lot
