Physical demands of a job are described from the more demanding jobs that require strength for lifting to the less physically demanding jobs that require skills such as seeing.

Physical conditions vary from quiet indoor jobs with no extremes of temperature to noisy outdoor jobs with extremes of temperature, moisture, vibrations, and work hazards.

Specific vocational preparation (svp) is symbolized by numbers ranging from 1 (short demonstration only) to 9 (10 years or more of training/education). The Office of Employment Statistics rates skill levels in 3 categories: unskilled (svp is 1-2), semi-skilled (svp 3-6), and skilled (svp 7-9).
