ACT requested assistance from the National Center for the Improvement of Educational Assessment (Center for Assessment) to investigate declines of scores for states administering the ACT to its 11th grade students in 2018. This request emerged from conversations among state leaders, the Center for Assessment, and ACT in trying to understand the…

The Objective Structured Clinical Examination (OSCE) is a ubiquitous part of medical education, although there is some debate about its value, particularly around possible impact on learning. Literature and research regarding the OSCE is most often situated within the psychometric or competency discourses of assessment. This paper describes an…

Mixed-format assessments are increasingly being used in large scale standardized assessments to measure a continuum of skills ranging from basic recall to higher order thinking skills. These assessments are usually comprised of a combination of (a) multiple-choice items which can be efficiently scored, have stable psychometric properties, and…

This study proposes a new item parameter linking method for the common-item nonequivalent groups design in item response theory (IRT). Previous studies assumed that examinees are randomly assigned to either test form. However, examinees can frequently select their own test forms and tests often differ according to examinees' abilities. In such…

Estimates of the validity of random short forms can serve as benchmarks against which to appraise the validity of particular short forms. Formulas are presented for estimating the validity of random short forms and illustrated with Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Minnesota Multiphasic Personality Inventory data.

Three studies explored the effects of grouping versus randomized items in questionnaires on internal consistency and test-retest reliability with samples of 80, 80, and 100, respectively, university students and undergraduates. The 2 correlational and 1 experimental studies were reasonably consistent in demonstrating that neither format was…

The authors of this volume's stimulus papers have taken on the challenge of developing measures of teachers' mathematical knowledge for teaching (MKT). This task involves multiple decisions and considerations, including: (1) How does one specify the body of knowledge being assessed? What warrants are offered for those choices?; (2) How does one…

This paper summarizes the standardized procedures and psychometric standards states must follow in developing performance-based assessment. The National Reporting System (NRS), which serves as the accountability system for federally funded adult education and literacy programs, requires that states have their local programs assess educational gain…
