Abstract: Common problem arising in the everyday practice of ability evaluation using tests is how one can compare or equate the scores obtained on different tests or different forms of the same test. Under the main assumption that these tests are based on the same unidimensional latent trait, their scores can be compared using the IRT calibration of the items in both tests. In this paper a procedure for test score equating, based on the sequence of tests with common items in each test are considered. 2010 Mathematics Subject Classification: 91E10, 91E45.
