Title I Technical Assistance Manual

b. A written job description prepared before advertising or interviewing applicants for a job

The ADA does not require an employer to develop or maintain job descriptions. A written job description that is prepared before advertising or interviewing applicants for a job will be considered as evidence along with other relevant factors. However, the job description will not be given greater weight than other relevant evidence.

A written job description may state that an employee performs a certain essential function. The job description will be evidence that the function is essential, but if individuals currently performing the job do not in fact perform this function, or perform it very infrequently, a review of the actual work performed will be more relevant evidence than the job description.

If an employer uses written job descriptions, the ADA does not require that they be limited to a description of essential functions or that "essential functions" be identified. However, if an employer wishes to use a job description as evidence of essential functions, it should in some way identify those functions that the employer believes to be important in accomplishing the purpose of the job.

If an employer uses written job descriptions, they should be reviewed to be sure that they accurately reflect the actual functions of the current job. Job descriptions written years ago frequently are inaccurate.

For example: A written job description may state that an employee reads temperature and pressure gauges and adjusts machine controls to reflect these readings. The job description will be evidence that these functions are essential. However, if this job description is not up-to-date, and in fact temperature and pressure are now determined automatically, the machine is controlled by a computer and the current employee does not perform the stated functions or does so very infrequently, a review of actual work performed will be more relevant evidence of what the job requires.

In identifying an essential function to determine if an individual with a disability is qualified, the employer should focus on the purpose of the function and the result to be accomplished, rather than the manner in which the function presently is performed. An individual with a disability may be qualified to perform the function if an accommodation would enable this person to perform the job in a different way, and the accommodation does not impose an undue hardship. Although it may be essential that a function be performed, frequently it is not essential that it be performed in a particular way.

For example: In a job requiring use of a computer, the essential function is the ability to access, input, and retrieve information from the computer. It is not "essential" that a person in this job enter information manually, or visually read the information on the computer screen. Adaptive devices or computer software can enable a person without arms or a person with impaired vision to perform the essential functions of the job.

Similarly, an essential function of a job on a loading dock may be to move heavy packages from the dock to a storage room, rather than to lift and carry packages from the dock to the storage room.

(See also discussion of Job Analysis and Essential Functions of a Job, below).

If the employer intends to use a job description as evidence of essential functions, the job description must be prepared before advertising or interviewing for a job; a job description prepared after an alleged discriminatory action will not be considered as evidence.
