The traditional method for computing test-retest reliability suffers from a number of defects. Its underlying methodology is not rigorous either. The purpose of this paper is to introduce the technique of quadratic assignment paradigm (QAP) and to apply this methodology to the computation of test-retest reliability. It also provides an example to show the advantages of the OAP over the traditional method. It is concluded that the OAP can be applied to the computation of test-retest reliability, provide a more objective, rigorous and precise estimate of test-retest reliability than the traditional method does,and be used to test for significance of stability and randomness. For future applications, the OAP technique is recommended as a substitute for the traditional method in computing test-retest reliability.
