The script concordance (SC) test was conceived to measure knowledge organization, the presence of links between items of knowledge which allow for interpretation of data in clinical decision making situations. Earlier studies have shown that the SC test has good psychometric qualities and overcomes some of the limitations of simulation clinical testing. This study explores the predictive validity of the test. ⋯ The authors assumed that the richness of knowledge organization, as indicated by SC test scores, would predict part of the performance on the measures of clinical reasoning (SAMP and SOO), but would predict less well performance on the OSCE which measures both clinical skills and clinical reasoning. Data found in the study are coherent with this hypothesis. This is evidence in favour of the construct validity of the SC test. It also indicates that, in the context of certification assessment, if a candidate has shown good organization of clinical knowledge at an early point in training, it can be expected that he/she will show good organization at subsequent measurements of this kind of knowledge. This appears to be true even if the later measures bear on a wider clinical domain.
