In testing organizations, a pivotal undertaking within the test development cycle involves constructing multiple parallel forms, each comprising items with comparable characteristics and qualities. Drawing from the perspective of equivalence as akin joint distributions of test item traits, we leverage the matching capabilities offered by the PSMATCH procedure to establish links between item selections through matching, thereby enabling the construction of uniform parallel tests. The goal of assembling psychometrically equivalent tests transforms into the task of generating joint distributions of item characteristics resembling a known distribution. We elucidate the principle and essential concepts underlying this process, demonstrating how PROC PSMATCH automates the creation of parallel tests. Intended for an audience with a basic understanding of SAS/STAT® software, this work offers insights into streamlining test development procedures. |
