Think of a job description as a “snapshot” of a job. The job description needs to communicate clearly and concisely what responsibilities and tasks the job entails and to indicate, as well, the key qualifications of the job – the basic requirements (specific credentials or skills) – and, if possible, the attributes that underlie superior performance.

Warning! A job description is generally regarded as a legal document. Any references to race, color, religion, age, sex, national origin or nationality, or physical or mental disability is illegal.
