A Bibliometric Analysis of Equating Research: Unveiling Trends, Collaborations, and Influential Works

Abstract

Equating in standardized testing is crucial for ensuring equitable outcomes for test-takers across different test versions, enabling accurate decision-making based on test scores. This study evaluates scientific publications on equating using bibliometric methods. This analysis will examine the research ecosystem, international and institutional collaborations, trending topics and their temporal evolution, characteristics of impactful research, and the latest emerging theme in the equating literature. Data was selected using the Scopus database, and 327 relevant papers were identified using a methodical screening process. The comprehensive bibliometric analyses employed the Biblioshiny and VOSviewer tools. The results indicated a strong research environment, with the United States and Turkey as the main contributors. The research identified collaboration networks and key institutions, highlighting the importance of international cooperation. The study identified common topics such as item response theory, simulation studies, and population invariance. The analysis identified thematic clusters related to methodological intricacies, accuracy evaluation, and equating method development. The distinguishing features of highly cited papers were their meticulous evaluation of equating methods, incorporation of item response theory, and creation of proper equating instruments. Future research must focus on fostering international collaborations, promoting interdisciplinary perspectives, and employing advanced statistical tools and computational resources to improve current equating techniques, develop innovative approaches, and address new challenges in the field of equating.
