The multiple mini-interview (MMI) has become an increasingly popular admissions method for selecting prospective students into professional programs (e.g., medical school). The MMI uses a series of short, labour intensive simulation stations and scenario interviews to more effectively assess applicants' non-cognitive qualities such as…

Fidelity assessment has received renewed attention in recent years, particularly as distinctions have been made in implementation science between intervention fidelity and implementation fidelity. Considering both types of fidelity has been recommended when developing fidelity instruments. In the present article, we describe development of the…

Allowing respondents to retake a cognitive ability test has shown to increase their test scores. Several theoretical models have been proposed to explain this effect, which make distinct assumptions regarding the measurement invariance of psychometric tests across test administration sessions with regard to narrower cognitive abilities and general…

Accepting that school based assessment may have the potential to bring additional reliability to the assessment outcomes of an educational system, this research uses Generalizability Theory to address the question "why school based assessment is not a universal feature of high stakes assessment systems"? Three major issues are identified: (a)…

Although substantial attention has been directed toward building the psychometric evidence base for academic assessment methods (e.g., state mastery tests, curriculum-based measurement), similar examination of behavior assessment methods has been comparatively limited, particularly with regard to assessment purposes most desirable within…

The authors center their presentation of material around a conceptual understanding of psychometric issues, such as validity and reliability, and on purpose rather than procedure, the "why" rather than the "how to." Their goal is to introduce psychometric principles at a level that is deeper and more focused than found in introductory…

The extent to which a scale score generalizes to a latent variable common to all of the scale's indicators is indexed by the scale's general factor saturation. Seven techniques for estimating this parameter--omega[hierarchical] (omega[subscript h])--are compared in a series of simulated data sets. Primary comparisons were based on 160 artificial…
