The final step in the test development process was to establish cut scores for each CAMERA instrument. The methodology used to derive the cut scores was multi-pronged, drawing on information gathered during the usage of the original CAMERA and on data analyzed in the second pilot phase of the refinement project. For each operational test instrument, the mean, median and range of pilot scores were considered for each task, along with the average performance of groups whose LBS levels were known. The expert judgement of the test developers was also brought to bear throughout this process, which was informed by the criteria and specifications that had guided the design of tasks for the refined instruments.
