Item Pool Maintenance in the Presence of Item Parameter Drift.
Bock, R. Darrell; And Others
Journal of Educational Measurement, v25 n4 p275-85 Win 1988
Differential drift of item location parameters over a 10-year period is demonstrated in data from the College Board Physics Achievement Test. Item content and secondary school curricula shifts are associated with drift. Statistical procedures for detecting item parameter drift in item pools for long-term testing programs are proposed.
