Background: Few researchers have the data required to adequately understand how the school environment impacts youth health behaviour development over time.

Methods/design: COMPASS is a prospective cohort study designed to annually collect hierarchical longitudinal data from a sample of 90 secondary schools and the 50,000+ grade 9 to 12 students attending those schools. COMPASS uses a rigorous quasi-experimental design to evaluate how changes in school programs, policies, and/or built environment (BE) characteristics are related to changes in multiple youth health behaviours and outcomes over time.

Determining admission criteria that will predict successful student outcomes is a challenging undertaking for newly established health professional programs. This study examined data from the students who entered a medical radiation sciences program in September 2002. By analyzing the correlation between undergraduate GPA, grades in undergraduate science courses, performance in program coursework, and post-graduation certification examination results, the authors determined admission criteria that were linked to successful student outcomes for radiological technology and radiation therapy students.

Purpose: This study investigates (a) whether items within the Multiple-Choice Questions component of the Medical Council of Canada's Qualifying Examination Part I exhibit local dependencies and (b) potential sources of such dependencies.

Method: The dimensionality of each of six discipline-based subtests was assessed based on exploratory nonlinear factor analyses. A standardized Fisher's z statistic was used to test residual item correlations for local item dependencies.

Problem Statement And Background: Examinees can make three types of errors on the short-menu questions in the Clinical Reasoning Skills component of the Medical Council of Canada's Qualifying Examination Part I: (1) failing to select any correct responses, (2) selecting too many responses, or (3) selecting a response that is inappropriate or harmful to the patient. This study compared the information provided by equal and differential weighting of these errors.
