A Hierarchical IRT Model for Criterion-Referenced Measurement
A hierarchical IRT model is proposed for mastery classification in criterionreferenced measurement. In this model, items measuring the same criterion are grouped, and a difficulty and discrimination parameter of the criterion is estimated on the same scale as the person and item parameters. The level of proficiency of a student with respect to the criterion is determined by the probability of s...
متن کاملVariance Decomposition Using an IRT Measurement Model
Large scale research projects in behaviour genetics and genetic epidemiology are often based on questionnaire or interview data. Typically, a number of items is presented to a number of subjects, the subjects' sum scores on the items are computed, and the variance of sum scores is decomposed into a number of variance components. This paper discusses several disadvantages of the approach of anal...
متن کاملValidity of cardiorespiratory fitness criterion-referenced standards for adolescents.
PURPOSE The clinical utility of cardiorespiratory fitness (CRF) criterion-referenced standards (FITNESSGRAM) has not been tested in adolescents. We aimed to determine the ability of the FITNESSGRAM standards to discriminate between low and high cardiovascular disease (CVD) risk in a population-based sample of US adolescents. METHODS Participants included 1247 adolescents (45.7% females) aged ...
متن کاملEstimating Criterion-referenced Standards for Multiple-choice Examinations
Four methods were studied for setting a standard on a written examination containing several clinical discipline subtests. The NBME method yielded the most consistent estimate. The Angoff and Ebel methods yielded slightly less consistent estimates. All estimates were more consistent when computed as the average of discipline standards rather than the judges' personal standards. All but the Esse...
متن کاملAudit and summative assessment: a criterion-referenced marking schedule.
BACKGROUND 1996 will see the introduction of summative assessment of general practitioner registrars (trainees). One part of this assessment is the written submission of practical work. In the west of Scotland, audit projects have been chosen as the format for practical work. A valid and reliable marking schedule for such projects is needed. AIM A study was undertaken to develop a criterion-r...
