Sheet with Instructions, Job Analysis Blank for Trades and Industrial Positions for Test Selections Purposes


By the early 1950s, the U.S. Civil Service Commission had developed a series of tests designed to measure various job skills. To determine which tests should be given to candidates for a given job, it used something called the J-Coefficient. This form was designed to determine the J-coefficient for various trades and industrial positions. As the instructions explain, six or more people who knew the job were to meet and each be given one of the forms (in a crunch, three raters would do). Each form listed 62 job skills. If a skill was not important to the job, it was to be marked with a zero. If of some importance it was given a check mark. If of extreme importance, it received a +. Brief comments were encouraged.

The use of J-coefficients is sometimes associated with Ernest S. Primoff (1913-1997).
