How this page is built
Education, experience, training and Job Zone come from O*NET 31.0 survey data for the occupation. The typical entry-level education, work experience and on-the-job training lines come from BLS Employment Projections, 2025–35. O*NET answers with low-precision estimates are not shown, and an answer is called the most common only when no hidden answer could be larger. Stepping-stone roles use our skill-match score: Skill match is the cosine similarity of the two occupations' skill profiles: for each of 35 O*NET skills (10 essential, 25 transferable) we multiply importance by level and subtract the average across all occupations, then compare the direction of the two profiles. 100 means identical shape; 0 means unrelated or opposite (negative values are shown as 0). Only occupations that O*NET itself lists as related are compared.
