ETS Research Report Series, Dec 2014
The purpose of this study is to investigate the impact of discrete anchor items versus passage-based anchor items on observed score equating using empirical data.This study compares an "SAT"® critical reading anchor that contains more discrete items proportionally, compared to the total tests to be equated, to another anchor that contains fewer discrete items and more passage-based items proportionally. Both of these anchors were administered in an SAT administration. The impact of anchor type on equating was evaluated with respect to equating bias. The results clearly reveal that the anchor with more discrete items almost always leads to more accurate equating functions than does the anchor with more passage-based items.
