Go deeper on this role
How this is built. Tasks, skills, and work-environment ratings come from the
U.S. Department of Labor's O*NET occupational analysis — job analysts survey real workers, so this is the
closest thing to "what the job is actually like" in public data. Skill scores are O*NET Importance
ratings and environment measures are Context ratings — both on O*NET's 1–5 scale
(1 = the floor: not important / never). We rescale them so 1 maps to 0 and 5 maps to 100, giving a
relative reading for easy comparison — it is not a percentage. This task-and-skill detail comes straight from the O*NET database — it's
pulled straight from the survey, not invented. Figures describe the typical role, not any one person's job.
