DB82 is correct, I USED to be in Sterling...I left for another job back in 2003.
Macop is also "technically" correct. HRD PAT standards can only be used to deny employment, however, the PT test they run can be used as an "evaluation" of cadidates and that "evaluation" can be used to determine a rank order for proceeding in the process. If no candidates "passed", they could not be denied employment based on that alone. This is similar to ranking candidates higher based on education, training, etc. Someone may meet minimum standards (i.e. PAT and GED), but may be ranked lower than someone with a B.S. and higher scores on the PT test. The "trick" is to establish a set number of people, prior to the test, who will proceed and hope that at least that number "passes" the test. You are considering the "best" candidates based on performance, not denying someone who didn't "pass".
If the set number to proceed is 3 and only 2 pass the Cooper Standards, the third person to be included would be the one who "failed" Cooper with the highest marks. It was always questionable, but when I was there I was willing to make the argument in court if anyone filed suit against us. Fortunately, it never came to that.
Additionally, all of their officers are paid a stipend every year if they maintain their level of fitness and pass a yearly P.T. test. Great department, tough town politics.
