#ScoreComparability

Growth across Grades and Common Item Grade Alignment in Vertical Scaling Using the Rasch Model Vertical scales are frequently developed using common item nonequivalent group linking. In this design, one can use upper-grade, lower-grade, or mixed-grade common items to estimate the linking const...

In a recent article in EM:IP, Student et al. examine the use of upper-grade, lower-grade, or mixed-grade common items to estimate the linking constants that underlie the absolute measurement of growth.

Comparative Analysis of Psychometric Frameworks and Properties of Scores from Autogenerated Test Forms This paper explores the psychometric properties of scores derived from autogenerated test forms by introducing three conceptual frameworks: Alternate Test Forms, Randomly Parallel Forms, and Approxim...

In a recent commentary in EM:IP, Lee and Kim explore the psychometric properties of scores derived from autogenerated test forms by introducing three conceptual frameworks and comparing them in a simulation study.
