Calculation of the acceptable level of performance (ALP) for a MCQ test



Calculation of the acceptable level of performance    (ALP) for a MCQ test
1. Definition
The acceptable level of performance is a threshold value making it possible to decide (according to absolute criteria) whether a student "who knows barely enough" should be passed or failed. Calculation of the ALP for a test is not valid unless the number of MCQ is more than 30. Use of the ALP involves an advance judgment (before the test) on the relative difficulty of each question and enables a judgment based on the test as a whole to be made. Calculation of the ALP depends on the collective decision of several teachers each of whom has first made an independent judgment.
