Using Restricted Latent Class Models to Map the Skill Structure of Achievement Items.

Haertel, Edward H.

Journal of Educational Measurement, v26 n4 p301-21 Win 1989

A method is presented for using a restricted latent class model--a binary skills model--to determine skills required by a set of test items. Results from the method's application to reading achievement data for about 63,000 fourth graders indicate that the model offers useful information on test structure and examinee ability. (TJH)
