A series of behavioral expectation scale (BES) applications were analyzed in an attempt to point out an appropriate number of dimensions to be in cluded in such studies. Data from 4 independent samples, representing 3 different occupations, and incorporating a total of 436 multidimensional evaluations were subjected to factor analysis. Re sults reflected the lack of unique information con tributed when the number of dimensions exceeds 9. The problem of lack of dimension independence was discussed in terms of theory and application to multidimensional performance evaluation. Sug gestions are advanced for limiting the number of dimensions as a potential solution to information redundancy.
