Item Analysis: A Short-Cut Statistic for Mastery Tests.

Harris, Deborah J.; Subkoviak, Michael J.

Educational and Psychological Measurement, v46 n3 p495-507 Aut 1986

This study examined three statistical methods for selecting items for mastery tests: (1) pretest-posttest; (2) latent trait; and (3) agreement statistics. The correlation between the latent trait method and agreement statistics, proposed here as an alternative, was substantial. Results for the pretest-posttest method confirmed its reputed limitations.
