Welcome to the ITEMS Portal!

The ITEMS portal is your entry point into a world of learning in educational measurement and assessment. ITEMS modules are its centerpiece, which are short self-contained lessons with various supporting resources that facilitate self-guided learning, team-based discussions, as well as professional instruction. In addition, you can explore a network of other professional organizations, stay up-to-date via news feeds, and contribute to the success of the portal. Enjoy your learning experience!

Digital Module 10: Rasch Measurement Theory
In this digital ITEMS module, Dr. Jue Wang and Dr. George Engelhard Jr. describe the Rasch measurement framework for the construction and evaluation of new measures and scales and demonstrate the estimation of core models with the Shiny_ERMA and Winsteps programs. Keywords: invariance, item fit, item response theory, IRT, person fit, model fit, multi-faceted Rasch model, objective measurement, R, Rasch measurement, Shiny_ERMA, Winsteps
Digital Module 11: Bayesian Psychometrics
In this digital ITEMS module, Dr. Roy Levy discusses how Bayesian inference is a mechanism for reasoning in probability-modeling framework, describes how this plays out in a normal distribution model and unidimensional item response theory (IRT) models, and illustrates these steps using the JAGS software and R. Keywords: Bayesian psychometrics, Bayes theorem, dichotomous data, item response theory (IRT), JAGS, Markov-chain Monte Carlo (MCMC) estimation, normal distribution, R, unidimensional models
Digital Module 12: Think-aloud Interviews and Cognitive Labs
‚ÄčIn this digital ITEMS module, Dr. Jacqueline Leighton and Dr. Blair Lehman review differences between think-aloud interviews to measure problem-solving processes and cognitive labs to measure comprehension processes and illustrate both traditional and modern data-collection methods. Keywords: ABC tool, cognitive laboratory, cog lab, cognition, cognitive model, interrater agreement, kappa, probe, rubric, thematic analysis, think-aloud interview, verbal report
Digital Module 13: Simulation Studies in IRT
In this digital ITEMS module, Dr. Brian Leventhal and Dr. Allison Ames provide an overview of Monte Carlo simulation studies (MCSS) in item response theory (IRT). MCSS are utilized for a variety of reasons, one of the most compelling being that they can be used when analytic solutions are impractical or nonexistent because they allow researchers to specify and manipulate an array of parameter values and experimental conditions (e.g., sample size, test length, and test characteristics). Key words: bias, bi-factor model, estimation, graded response model, item response theory, mean squared error, Monte Carlo, simulation, standard error, two-parameter logistic model
Digital Module 14: Planning and Conducting Standard Setting
In this digital ITEMS module, Dr. Michael B. Bunch provides an in-depth, step-by-step look at how standard setting is done. It does not focus on any specific procedure or methodology (e.g., modified Angoff, bookmark, body of work) but on the practical tasks that must be completed for any standard setting activity. Keywords: achievement level descriptor, certification and licensure, cut score, feedback, interquartile range, performance level descriptor, score reporting, standard setting, panelist, vertical articulation
Digital Module 15: Accessibility of Educational Assessments
In this digital ITEMS module, Dr. Ketterlin Geller and her colleagues provide an introduction to accessibility of educational assessments. They discuss the legal basis for accessibility in K-12 and higher education organizations and describe how test and item design features as well as examinee characteristics affect the role that accessibility plays in evaluating test validity during test development operational deployment. Keywords: Accessibility, accommodations, examinee characteristics, fairness, higher education, K-12 education, item design, legal guidelines, test development, universal design
Digital Module 16: Longitudinal Data Analysis
In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically-defensible function that adequately summarizes both individual change as well as the average response. Keywords: fixed effect, linear mixed effects models, longitudinal data analysis, multilevel models, population-average, random effect, regression, subject-specific, trajectory
