O*NET's 1–5 scale describing how much preparation an occupation typically needs.
What it means
A job zone is an O*NET grouping that sorts occupations by how much education, training, and experience they typically require.
There are five job zones. Zone 1 covers occupations needing little or no preparation, while Zone 5 covers occupations that typically need extensive preparation such as advanced degrees and long experience.
Job zones help career-changers gauge the realistic on-ramp to a role: a lower zone usually signals a shorter typical preparation path than a higher one.
A job zone describes the typical preparation level of an occupation, not a fixed rule — it is not a guarantee that a given zone leads to placement or a particular wage.
We present job zones as planning context only and never as a promise about hiring, income, or earnings for any individual.
