This study investigates the measurement precision of MST compared to CAT and compared to P&P test for the one-, two-, and three-parameter logistic (1-, 2-, and 3PL) models when the test is completely set-based. Results showed that MST performed better for the 2- and 3PL models than an equivalent-length p&P test in terms of reliability and conditional standard of error of measurement. In addition, findings showed that MST performed better for the 1- and 2PL models than for an equivalent-length CAT test. For the 3PL model, MST and CAT performed about the same.
