The Objective Borderline Method: a probabilistic method for standard setting
2015
A new probability-based standard setting technique, the Objective Borderline Method (OBM), was introduced recently. This was based on a mathematical model of how
test scoresrelate to student ability. The present study refined the model and tested it using 2500 simulated data-sets. The OBM was feasible to use. On average, the OBM performed well with specificity .88, sensitivity .51,
false positive rate3.4% and false negative rate 26%. These indices were insensitive to the borderline score range. This probability-based standard setting may be a useful addition to the range of standard setting methods available.
