A Comparison of the Performance of Simulated Hierarchical and Linear Testlets.

Wainer, Howard; And Others

Journal of Educational Measurement, v29 n3 p243-51 Fall 1992

Computer simulations were run to measure the relationship between testlet validity and factors of item pool size and testlet length for both adaptive and linearly constructed testlets. Making a testlet adaptive yields only modest increases in aggregate validity because of the peakedness of the typical proficiency distribution. (Author/SLD)
