A revised system for numerically coding mixed standard scale (MSS) response combinations is proposed, and the psychometric implications of the new system are examined in the context of a comparative empirical study. The MSS ratings and graphic scale ratings obtained from 18 police supervisors for a total of 92 police patrol officers suggest that the proposed system does not substantially alter the findings of such comparative studies. The data further suggest that contradictions in the literature regarding the relative psychometric strengths and weaknesses of MSS ratings are probably not a function of the coding system originally proposed by F. Blanz and E. E. Ghiselli (1972) for translating MSS responses into numerical ratings. Adoption of the revised system is nevertheless recommended on the basis of (a) anticipated reliability increments and (b) greater "face validity" of the coding system, thereby rendering the MSS format potentially more acceptable to raters and ratees.
