This simulation study examines the measurement precision, item exposure rates, and the depth of the MAP Growth item pools under various grade-level restrictions.

The purpose of this literature review is to study the advantages and limitations of various through-course summative assessment models with the goal of informing the design of the NWEA through-year solution.

This study investigates the impact of three different IRT scaling and equating methods in building an item bank of tests from 23 years of a national licensure exam . The study focuses on several key psychometric issues including scaledriftandequatingerrors.

This study examined the measurement stability of a set of Rasch measurement scales that have been in place for almost 40 years.

The major purpose of this paper is to investigate the effects of CAT test design and bank distribution on the content coverage and the efficiency of the tests.

These studies are conducted based on assumptions under regular conditions for fixed test forms, such as no missing responses and normal distribution of unidimensional ability for a population.

The purpose of this study is to investigate the effect of missing data in computerized adaptive tests (CAT) on test construct validity.
