Abstract/Description: The Early Fractions Test v2.2 is a paper-pencil test designed to measure mathematics achievement of third- and fourth-grade students in the domain of fractions. The purpose, or intended use, of the Early Fractions Test v2.2 is to serve as a measure of student outcomes in a randomized trial designed to estimate the effect of an educational intervention on student understanding and ability in the domain of early fractions concepts. In this report, we discuss our exploration of options for scoring and data modeling and make recommendations for optimal scoring and data modeling procedures. We also report on the results of data modeling, including analyses of dimensionality, scale reliability estimates, item difficult estimates, test information, and the distribution of student ability estimates. The results of these analyses are largely consistent with the findings from the analysis of data from the previous version of the Early Fractions Test (Schoen, Liu, Yang, & Paek, 2017).
