Simulation study for evaluating MAP Growth item pools with grade-level constraints
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.
Topics: Computer adaptive testing, Test design


Robust IRT scaling: Considerations in constructing item bank from tests across years
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.
