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.
