Predictors of success on the ARRT's MRI exam.

The research described in this article investigated the relationship between selected background variables and the performance of 2546 candidates who took a certification examination in magnetic resonance imaging in 1995. Five variables related to training and experience were investigated: type of training in MR, amount of training in MR, years of experience in MR, hours per week in MR and number of MR scans performed per week. In addition, scores from an entry-level certification exam in general radiography were studied. Results indicated that all six variables were significantly related to MRI exam scores, with prior performance on the radiography exam exhibiting the strongest relationship. Implications of the findings for policy and practice are discussed.
