An analytical framework is described through which voluntary attrition can be predicted. The approach incorporates Marshallian Utility Theory and a Maximum Likelihood Estimation procedure to evaluate a specific individual's propensity to attrit. The approach was tested twice at the United States Air Force Academy where it was able to correctly predict over a third of the voluntary losses a priori on a by-name basis. These results indicate that the approach has practical usefulness as an operational tool. (Author/RC)
