Abstract:

Composites of test scores are used in selection and classification of enlisted personnel. If a selection composite is replaced by a new composite with higher predictive validity, mean performance of the recruits increases. Formulas for calculating the performance gain require simplifying assumptions. This research memorandum shows with an example that the formulas are very sensitive to violations of these assumptions and hence are not dependable enough for use in operational decisions.
