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 (0–5) and environment measures are Context ratings (0–5), both rescaled to 0–100 here for
easy reading. 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.
