Different types of performance appraisals are appropriate for different types of work. Criteria for judging the acceptability or lack of adequate work completion are measured differently in different situations, based on the type of labor being assessed and the ways in which appraisals are conducted.
Performance appraisal is a process by which organizations evaluate employee performance based on preset standards. The main purpose of appraisals is to help managers effectively staff companies and use human resources, and, ultimately, to improve productivity.
The productivity of an individual engaged in retail sales, for example, is most likely to be based on the number of units of merchandise sold and/or the amount of profit generated by the individual's sales efforts. The performance appraisal for such a position may include a tracing of monthly totals over a period of time and an evaluation of whether or not the employee is increasing the amount of sales generated over that period.
An educator, on the other hand, may be evaluated based on the number of students who graduate from high school with a given grade point average, or after analyzing the scores students achieve on standardized tests. This requires a very different process of collecting and applying data than the previous example.
