Job analysts who collect occupational information for the Dictionary of Occupational Titles observed and interviewed job incumbents representing 20 diverse occupations and rated each occupation on a wide variety of characteristics following standard United States Employment Services procedures. On the basis of four ratings, the large majority of 70 scales were found to have coefficient alpha (or KR‐20) reliabilities in excess of .SO, and 25 scales had reliabilities ranging from .90 to .98; a variance ratio procedure yielded largely consistent estimates. Reliabilities were similar to those found in an earlier study using different procedures and were similar to those from a well‐developed, occupa‐tionally anchored scale of “Job Complexity,” developed for this study. Scales representing broad, abstract job characteristics tended to have higher reliabilities than scales representing more concrete job characteristics.
