The model for educational measurement developed by George Rasch, a Danish psychometrician, is reviewed and its application to occupational educational testing discussed. The Rasch model is an adaptation from the theory of latent trait analysis. According to it, answering an item correctly is a function of the difficulty of the item and the ability…

This article presents evidence of the reliability and validity of a new paper-and-pencil test of proportional reasoning, Paper-and-Pencil Balance Beam Test. A Total of 627 individuals, aged 8-47, participated in the 3 studies discussed. Results support previous research which correlates performance on proportional reasoning problems with…

Monte Carlo simulation procedures were used to study the psychometric characteristics of two two-stage adaptive tests and a conventional "peaked" ability test. Results showed that scores yielded by both two-stage tests better reflected the normal distribution of underlying ability. Ability estimates yielded by one of the two stage tests…

To investigate the type of classroom testing format most appropriate for the Southwest Regional Laboratory (SWRL) Mod 2 Reading Program, three types of teacher-administered tests for the SWRL Second-Year Communication Skills Program were developed and tried out during the 1970-71 school year. The tests were administered by the classroom teacher as…

This report contains the Proceedings of the 1982 Item Response Theory and Computerized Adaptive Testing Conference. The papers and their discussions are organized into eight sessions: (1) "Developments in Latent Trait Theory," with papers by Fumiko Samejima and Michael V. Levine; (2) "Parameter Estimation," with papers by…
