A weighting strategy is employed to combine scores on the exercises and to form the total scores on the assessment. This weighting strategy is selected by another committee of teachers who must choose from among four predetermined weighting strategies. To make certification decisions (accomplished/not accomplished), the total score is compared to a predetermined passing score that is uniform across certificates. This performance standard is equivalent to receiving a just-passing score on each
