Job classification or Job grading is a simple, widely used method in which raters categorize jobs into groups; all the jobs in each group are of roughly the same value for pay purposes. The groups are called classes if they contain similar jobs or grades if they contain jobs that are similar in difficulty but otherwise different. Thus, in the federal government’s pay grade system, a “press secretary” and a “fire chief” might both be graded “GS-10” (Gs stands for “General Schedule”). On the other hand, in its job class system, the state of Florida might classify all “secretary IIs” in one class, all “maintenance engineers” in another and so forth.
