An effective personnel valuation program permits an improved appropriateness valuation result to be obtained by adjusting deviation of valuation by individual valuators from a standard. Valuators at posts able to perform appropriate valuation are set as reference data valuators. Initial valuation data produced by valuators in a valuator group other than the reference data valuators are adjusted such that its mean data is identical with the mean data of the valuation data produced by the reference data valuators with the mean data and the standard deviation of the valuation data by the reference data valuators as references. Also, standard deviation fluctuations of the valuation data are adjusted such that the standard deviation is identical with the standard deviation of the valuation data produced by the reference data valuators.
