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 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
Digital Module 17: Data Visualizations
In this digital module, Nikole Gregg and Dr. Brian Leventhal discuss strategies to ensure data visualizations achieve graphical excellence. The instructors review key literature, discuss strategies for enhancing graphical presentation, and provide an introduction to the Graph Template Language (GTL) in SAS to illustrate how elementary components can be used to make efficient, effective and accurate graphics for a variety of audiences. Key words: data visualization, graphical excellence, graphical template language, SAS
Digital Module 18: Automated Scoring
In this digital ITEMS module, Dr. Sue Lottridge, Amy Burkhardt, and Dr. Michelle Boyer provide an overview of automated scoring. They discuss automated scoring from a number of perspectives and provide two data examples, one focused on training and evaluating an automated scoring engine and one focused on the impact of rater error on predicted scores. Key words: automated scoring, hand-scoring, machine learning, natural language processes, constructed response items
Digital Module 19: Foundations of IRT Estimation
In this digital ITEMS module, Dr. Zhuoran Wang and Dr. Nathan Thompson introduce the basic item response theory (IRT) item calibration and examinee scoring procedures as well as strategies to improve estimation accuracy. Keywords: calibration, EM algorithm, estimation accuracy, item response theory (IRT), maximum likelihood estimation (MLE), maximum a posteriori (MAP), expected a posteriori (EAP), marginal maximum likelihood estimation (MMLE), scoring
Digital Module 20: Classroom Assessment Standards
In this digital ITEMS module, Dr. Caroline Wylie reviews the Classroom Assessment Standards with their three sets of standards: (1) Foundations (these six standards provide the basis for developing and implementing sound and fair classroom assessment); (2) Use (these five standards follow a logical progression from the selection and development of classroom assessments to the communication of the assessment results); and (3) Quality (these five standards guide teachers in providing accurate, reliable, and fair classroom assessment results for all students). Keywords: assessment design, classroom assessment, formative assessment, professional development
Digital Module 21: Results Reporting for Large-scale Assessments
In this digital ITEMS module, Dr. Francis O’Donnell and Dr. April Zenisky provide a firm grounding in the conceptual and operational considerations around results reporting for summative large-scale assessment and, throughout the module, highlight research-grounded good practices, concluding with some principles and ideas around conducting reporting research. Keywords: data, large-scale assessment, results, score reporting, validity, visualization
Digital Module 22: Supporting Decisions with Assessment
In this digital ITEMS module, Dr. Chad Gotch walks through different forms of assessment, from everyday actions that are almost invisible, to high-profile, annual, large-scale tests with an eye towards educational decision-making. Keywords: assessment literacy, classroom assessment, decision-making, formative assessment, in-the-moment assessment, interim assessment, large-scale assessment, major milepost, periodic check-in, unit test
Digital Module 23: Multidimensional Item Response Theory Graphics
In this digital ITEMS module, Dr. Terry Ackerman and Dr. Qing Xie cover the underlying theory and application of multidimensional item response theory models from a visual perspective. Keywords: centroid plot, clamshell plot, contour plot, item information curve, item information surface, multidimensional item response theory, MIRT, response surface, RShiny, test characteristic curve, test characteristic surface, vector
