How this page is built
Education, experience, training and Job Zone come from O*NET 31.0 survey data for the occupation. Stepping-stone roles use our skill-match score: Skill match is the correlation between the two occupations' skill profiles: for each of 35 O*NET skills (10 essential, 25 transferable) we multiply importance by level, subtract the average across all occupations, and correlate the two profiles. 100 means identical shape; 0 or below means unrelated. Only occupations that O*NET itself lists as related are compared.
