Normative data reported by publishers of the California Achievement Test, the Comprehensive Tests of Basic Skills, and the SRA Assessment Survey were used to illustrate a procedure for specifying goals for Title I programs in terms of normal curve equivalent (NCE) gains. The procedure was based on the amount of growth reflected in student reading…

The primary purpose of this research is to examine the impact of estimation methods, actual latent trait distributions, and item pool characteristics on the performance of a simulated computerized adaptive testing (CAT) system. In this study, three estimation procedures are compared for accuracy of estimation: maximum likelihood estimation (MLE),…

This study investigated the mathematics achievement test performance of 62 non-transient elementary school learners in accelerated schools using a longitudinal design. Both the California Achievement Test (CAT) and the Louisiana Educational Assessment Program (LEAP) test were included in this investigation. In particular, this study sought to…

The purpose of this study was to use realistically simulated data to evaluate various CAT designs for use with the verbal reasoning measure of the Medical College Admissions Test (MCAT). Factors such as item pool depth, content constraints, and item formats often cause repeated adaptive administrations of an item at ability levels that are not…

Various models of school effects on student achievement were applied in a study of reading and mathematics achievement in the 94 schools of the Oklahoma City Public Schools. The Leadership/Climate Inventory, completed by 1294 teachers, rated school principals in the areas of expectations, instructional leadership, forceful or dynamic style,…
