A Comparison among IRT True- and Observed-Score Equatings and Traditional Equipercentile Equating.

Han, Tianqi; And Others

Applied Measurement in Education, v10 n2 p105-21 1997

Stability among equating procedures was studied by comparing item response theory (IRT) true-score equating with IRT observed-score equating, IRT true-score equating with equipercentile equating, and IRT observed-score equating with equipercentile equating. On average, IRT true-score equating more frequently produced more stable conversions. (SLD)
