Profile of Hearing Ratings of the Job

Profile of hearing ratings of a job or occupation

A profile of hearing ratings of an occupation refers to the levels of hearing ability or auditory discrimination involved in the performance of the work. The ratings for hearing factors in a job profile (external link) do not indicate whether persons who are deaf or hard of hearing can or cannot perform the duties of that job. However, youth who are deaf or hard of hearing may find the information useful in terms of considering workplace accommodations that would enhance his or her employability.

The National Occupational Classification (NOC) website includes information on aptitudes, interests, involvement with data/people/things, physical activities, environmental conditions, education/training indicators, career progression and work settings. NOC provides 923 occupational profiles. The physical activities refer to seven main activities: vision, colour discrimination, hearing, body position, limb coordination and strengths.
