An investigation of item parameter invariance using focused calibration samples for MAP Growth
By: Wei He
Two studies were conducted to evaluate whether the existing MAP Growth item parameter estimates are invariant across different calibration samples. Study 1 explored the degree to which on-grade only item parameter estimates were comparable to their original all-grade counterparts. Study 2 explored the degree to which item parameter estimates using responses from the target grade plus the adjacent grades were comparable to their on-grade and all-grade counterparts.See More

This simulation study examines the measurement precision, item exposure rates, and the depth of the MAP Growth item pools under various grade-level restrictions.
From through-course summative to adaptive through-year models for large-scale assessment: A literature review
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.
