Classification decisions relate to situations in which a battery of predictor tests is used to alllocate subjects to a number of different assignment positions according to some pre specified quota proportions. In the case that the performance on the assignment criteria is continuously measurable, the efficiency of the predictor - based classification can be equated to the expected criterion score of the optimally assifned individuals : the allocation average. It is shown how a theorem proven by brogden can be used to estimate the allocation average assuming that the predictor intercorrelations and validities are known and that the predictor variables have a joint multivariate normal distribution. Compared to previous analytical procedures to estimate the efficiency of a classification, the proposed solution is much more generally applicable in that is no longer assumed that the predictor - based criterion estimates are both equally valid and equi- correlated and that all quota proportions are equal.
