Three study cohorts involving 199 gifted fifth graders, 190 gifted sixth graders, and 683 typical sixth graders were used to construct, validate, and pilot a computerized adaptive math test for placing fifth graders in a middle school mathematics gifted program. Results suggest the adaptive test has potential for talent identification. (Author/CR)

The reliability of four branching algorithms commonly used in computer adaptive testing (CAT) was examined. These algorithms were: (1) maximum likelihood (MLE); (2) Bayesian; (3) modal Bayesian; and (4) crossover. Sixty-eight undergraduate college students were randomly assigned to one of the four conditions using the HyperCard-based CAT program,…
