This SAS certification is not even a good hiring tool. This is a criterion
referenced test that is essentially pass-fail. Prospective employers can not
sort certified individuals by their score to pick the highest scorer. Nor can
the certificate holder claim any greater knowledge than his or her fellow
certificate holder or tie compensation to a particular level of achievement
vis-a-vis the test.
In certification testing you set you cut-point based on what a panel of experts
believes is the percent of minimally qualified candidates who will answer each
question correctly. Sometimes each question gets this rating and the score for
the test is the average of the item percents.
The bottom line is that certification indicates that the candidate is at least
minimally qualified. No inferences are possible beyond this simple statement.
