Samples of entering first-grade students were used to examine the predictive validity of the group administered Metropolitan Readiness Test (MRT) and the individually administered Meeting Street School Screening Test (MSSST). The advantage of the latter was found to possibly outweigh the advantage of efficiency in group administration. (Author/GK)

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…

The score distributions of the two methods of administration described in the title revealed comparable means, standard deviations, and general shape of distribution. With respect to validity coefficients, no appreciable differences were found. (JKS)
