Formal graduate education in a measurement related field provides a solid foundation for professionals who work on credentialing examinations. Those foundational skills are then expanded and refined over time as practitioners encounter complex and nuanced challenges that were not covered by or go beyond the context described in textbooks. For…

Administrative problems such as computer malfunction and power outage occasionally lead to missing item scores, and hence to incomplete data, on credentialing tests such as the United States Medical Licensing examination. Feinberg compared four approaches for reporting pass-fail decisions to the examinees with incomplete data on credentialing…

This article studied two methods to detect mode effects in two credentialing exams. In Study 1, we used a "modal scale comparison approach," where the same pool of items was calibrated separately, without transformation, within two TC cohorts (TC1 and TC2) and one OP cohort (OP1) matched on their pool-based scale score distributions. The…

In this data brief, we examine both the scores and pass rates for the Praxis 5403 School Psychology test (Praxis 5403) by racial-ethnic group and gender for the period September 1, 2023, to August 31, 2024. The Praxis 5403 is the most often used external assessment in school psychology, and a passing score on the Praxis 5403 is a requirement to…

Competency-based testing and credentialing (CBTC) initiatives aim to address inequity in adult education by fundamentally changing how states use GED®, HiSET®, and TASC™ test scores to award and withhold high school equivalency credentials. However, CBTC is inconsistent with how developers intend states to use those scores. Accordingly, it falls…

Since the onset of the pandemic in 2020, many credentialing organizations have incorporated online remote administration of their examinations to enable continuity of their programs. This paper describes a research study examining several high stakes credentialing examination programs that utilized mixed delivery modes, including online remote…

The properties of a blockchain such as immutability, provenance, and peer-executed smart contracts could bring a new level of security, trust, and transparency to e-learning. In this paper, we introduce our proof-of-concept blockchain-based e-learning platform developed to increase transparency in assessments and facilitate curriculum…
