Job Zone Three: Medium Preparation Needed
O*NET job zone · preparation tier
Job Zone Three: Medium Preparation Needed is one of O*NET's job zones — tiers that group occupations by how much preparation they typically require, combining experience, education, and on-the-job training into a single Specific Vocational Preparation (SVP) band. This zone covers 212 occupations employing about 35,139,240 workers, with a median wage of $60,690.
Preparation it takes
O*NET describes the typical path into occupations in this zone. These are descriptions of what the work usually requires — not rules, and many people enter by other routes.
| Experience | Previous work-related skill, knowledge, or experience is required for these occupations. For example, an electrician must have completed three or four years of apprenticeship or several years of vocational training, and often must have passed a licensing exam, in order to perform the job. |
| Education | Most occupations in this zone require training in vocational schools, related on-the-job experience, or an associate's degree. |
| Job training | Employees in these occupations usually need one or two years of training involving both on-the-job experience and informal training with experienced workers. A recognized apprenticeship program may be associated with these occupations. |
| SVP range | (6.0 to < 7.0) |
What occupations in this zone pay
Median annual wage across the occupations in this zone, from BLS OEWS (national, cross-industry, May 2024). The middle range shows the 25th–75th percentile of occupation medians — it describes the zone, not a guarantee for any one person or job.
| Median occupation wage | $60,690 |
| Middle range (p25–p75) | $49,255 – $76,300 |
| Occupations with wage data | 203 of 212 |
AI exposure in this preparation tier
Two published studies estimate how exposed each occupation is to today's AI. The OpenAI "GPTs are GPTs" study rates the share of an occupation's tasks a large language model (with tools) could speed up by half or more; averaged across the occupations in this zone it is 28% — 38th percentile of the job zones. The independent Felten/Raj/Seamans AI Occupational Exposure index averages -0.13 here.
Computed across the 212 of 212 occupations in this zone that carry a published exposure score.
AI exposure tends to rise with preparation — zones that require degrees and considerable experience are the most exposed, hands-on lower-preparation work the least. Exposure measures where AI could assist tasks, not a prediction that these jobs will be automated; high exposure most often means augmentation.
