Evaluation of the Efficiency of Item Calibration.

Vale, C. David; Gialluca, Kathleen A.

Applied Psychological Measurement, v12 n1 p53-67 Mar 1988

To determine which produced the most accurate item parameter estimates, four methods of item response theory were evaluated: (1) heuristic estimates; (2) the ANCILLES program; (3) the LOGIST program; and (4) the ASCAL program. LOGIST and ASCAL produced estimates of superior and essentially equivalent accuracy. (SLD)
