The aim of this study has been to compare two different systems for selection criteria for the Swedish officers’ programme. In order to compare the old and the new system, respectively, for cadet selection, the cadets’ achievements were compared to their selection criteria. The systems selection criteria were correlated to the cadets’ achievements in a correlation matrix. Subsequently, the connections were further investigated by semi-partial correlations and confidence intervals. In the study, there is evidence that indicates the previous system’s superior effectiveness compared to the new system; for example, regarding the selection of cadets likely to benefit from the programme. The selection criterion with the strongest connection to the cadet achievement was the cadets’ high school grades, which also seems to be a good indicator for predicting student achievement in civilian schools. If the Swedish Armed Forces want to enhance the study capabilities of future cadets, an advised method of achieving this would be to augment the significance of high school grades for the selection criteria.
