Adaptive tests are more efficient than fixed-length tests through the use of item response theory; adaptive tests also present students questions that are tailored to their proficiency level. Although the adaptive algorithm is straightforward, developing a multidimensional computer adaptive test (MCAT) measure is complex. Evidence-centered design…

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…

This module is designed for educators, educational researchers, and psychometricians who would like to develop an understanding of the basic concepts of validity theory, test validation, and documenting a "validity argument." It also describes how an in-depth understanding of the purposes and uses of educational tests sets the foundation…

The goal in personalized assessment is to best fit the needs of each individual test taker, given the assessment purposes. Design-in-Real-Time (DIRTy) assessment reflects the progressive evolution in testing from a single test, to an adaptive test, to an adaptive assessment "system." In this article, we lay the foundation for DIRTy…

The community of educational measurement researchers and practitioners has made many positive contributions to education, but has also become complacent and lost the public trust. In this article, reasons for the lack of public trust in educational testing are described, and core values for educational measurement are proposed. Reasons for…

Selection decisions have a major impact on our education, occupation, and quality of life, and the role of standardized tests in selection has always been a source of controversy. Here, I consider various definitions of fairness in measurement and selection--those emerging from within educational measurement and statistics, those from philosophy,…

The onset of the coronavirus pandemic forced schools and universities across the nation and world to close and move to distance learning rather immediately. Almost two years later, colleges and universities have reopened, and most students have returned to campuses, but distance learning still occurs at a much higher rate than before the beginning…

Thanks to COVID-19, schools were closed and tests were canceled. The result is that we may not see test-taking data typically seen before. For some analyses, sample sizes may not meet the minimum requirement. For others, the sample of test-takers may be different from previous years. In some situation, there may be no data at all. What do we do in…

In response to the COVID-19 pandemic, the American Board of Surgery (ABS) shifted from in-person to remote administrations of the oral certifying exam (CE). Although the overall exam architecture remains the same, there are a number of differences in administration and staffing costs, exam content, security concerns, and the tools used to give the…

One of the substantive changes in the 2014 Standards for Educational and Psychological Testing was the elevation of fairness in testing as a foundational element of practice in addition to validity and reliability. Previous research indicates that testing practices often do not align with professional standards and guidelines. Therefore, to raise…

The COVID-19 pandemic has accelerated the shift toward online learning solutions necessitating the need for developing online assessment solutions. Vendors offer online assessment delivery systems with varying security levels designed to minimize unauthorized behaviors. Combating cheating and securing assessment content, however, is not solely the…

The educational testing landscape is changing in many significant ways as evidence-based, principled assessment design (PAD) approaches are formally adopted. This article discusses the challenges and presents some score scale- and task-focused strategies for developing useful performance-level descriptors (PLDs) under a PAD approach. Details of…

Educators and researchers strive to build policies and practices on data and evidence, especially on academic achievement scores. When assessment scores are inaccurate for specific student populations or when scores are inappropriately used, even data-driven decisions will be misinformed. To maximize the impact of the research-practice-policy…

A multistage adaptive testing (MST) design was implemented for the Programme for the International Assessment of Adult Competencies (PIAAC) starting in 2012 for about 40 countries and has been implemented for the 2018 cycle of the Programme for International Student Assessment (PISA) for more than 80 countries. Using examples from PISA and PIAAC,…

Educational tests are standardized so that all examinees are tested on the same material, under the same testing conditions, and with the same scoring protocols. This uniformity is designed to provide a level "playing field" for all examinees so that the test is "the same" for everyone. Thus, standardization is designed to…
