Employers should develop job descriptions that clearly define the essential functions of every job before advertising the job or interviewing applicants. A job description should have clear, concise, non-technical language, and avoid unnecessary words. The job description should focus on words that have a single meaning with detailed explanations for words that may be interpreted differently. Each sentence should begin with an active verb and use the present tense. Examples of job functions should be provided. The desired outcome of the work should be described, rather than one method for accomplishing that outcome. For example, instead of "writes down notes during meetings" put "records notes during weekly meetings." Writers should avoid using gender-specific language, jargon, technical language, proprietary names (Xerox), and ambiguity.
Prepare job summaries, if relevant. You can use the job description template you use for each position that you advertise by filling in the template with the information that is relevant to that position. However, if you do (or expect to do) a lot of hiring of a particular position, you might make a special template that includes a summary of that job. This will save you some time.
