To help ensure that assessments are properly administered, states have developed policies about who can administer or proctor assessments, and the training they must have. This report presents the findings of our analysis of states' 2021 policies on the qualifications and requirements for test administrators, proctors, and accommodations providers…

The emergence of digital-first assessments is prompting reconsideration of, and innovation in, aspects of psychometrics, test validation, and test use. Using the Duolingo English Test (DET) as an example, this three-paper series seeks to address issues concerning the estimation of classification consistency and the reporting of results for such…

Learning outcome modeling is a technical underpinning for the successful evaluation of learners' learning outcomes through computer-based assessments. In recent years, collaborative filtering approaches have gained popularity as a technique to model learners' item responses. However, how to model the temporal dependencies between item responses…

"Integrative evaluation" is an approach with two main phases: identification of plausible rival hypotheses and integration of rival hypotheses. The first phase may correspond to traditional adversary evaluation, whereas the second phase, that is not included in adversary evaluation, requires integrative thinking which can be applied when…

Discussions around assessment integrity often focus on the exam conditions and the motivations and values of those who cheated in comparison with those who did not. We argue that discourse needs to move away from a binary representation of cheating. Instead, we propose that the conversation may be more productive and more impactful by focusing on…

Though a substantial amount of research exists on imputing missing scores in educational assessments, there is little research on cases where responses or scores to an item are missing for all test takers. In this paper, we tackled the problem of imputing missing scores for tests for which the responses to an item are missing for all test takers.…

Chiang Mai Rajabhat University Test of English Proficiency (CMRU-TEP) is a required English proficiency test for all CMRU students before graduation. Despite its meticulous design, there is an opportunity for students to improve their scores through focused efforts and targeted support. This study employs an explanatory sequential mixed-methods…

This dissertation was designed to foster a deeper understanding of population invariance in the context of composite-score equating and provide practitioners with guidelines for addressing score equity concerns at the composite score level. The purpose of this dissertation was threefold. The first was to compare different composite equating…

After providing key definitions well as substantial supportive evidence for the instructional process under consideration, this analysis identifies a serious shortcoming in the way that many U.S. educators are currently encouraging teachers' adoption of the formative-assessment process--a teaching approach informed by students' en route test…

Mediation analysis is widely used to study whether the effect of an independent variable on an outcome is transmitted through a mediator. Bayesian methods have become increasingly popular for mediation analysis. However, limited research has been done on formal Bayesian hypothesis testing of mediation. Although hypothesis testing using Bayes…

The use of computerized adaptive testing algorithms for ranking items (e.g., college preferences, career choices) involves two major challenges: unacceptably high computation times (selecting from a large item pool with many dimensions) and biased results (enhanced preferences or intensified examinee responses because of repeated statements across…

Ten years ago, the author worked as the Director of Assessments for the District of Columbia Public Schools (DCPS). For temporal context, the author arrived after the first of the infamous test cheating scandals and left just before the incident that spawned a second. Indeed, the author filled a new position created to both manage test security…

This research applied a web-based dynamic assessment system, GPAM-WATA system, to help low English achievers to perform self-directed learning of junior high school English grammar. A quasi-experimental design was adopted. A total of 124 seventh graders from four classes participated in this research. Participants were randomly divided into the…

This study's primary purpose was to determine how students with a learning disability (LD) in mathematics react in different testing environments, and whether changing the testing parameters can improve the outcomes. Quantitative data was collected through questionnaires, heart rates, and math fluency probes. These data were used to test the…

Example-generation tasks have been suggested as an effective way to both promote students' learning of mathematics and assess students' understanding of concepts. E-assessment offers the potential to use example-generation tasks with large groups of students, but there has been little research on this approach so far. Across two studies, we…
