What the data actually shows: the top 10 is not a healthcare sweep. 4 of the top 10 slots go to skilled trades (electrician, plumber, elevator installer) whose apprenticeship-style licensing counts cumulative classroom-plus-on-the-job hours over several years, which lands them alongside 6 healthcare/mental-health/animal-care professions with doctoral-style academic + clinical training. Reported hours are not directly comparable across licensing models, an apprenticeship hour and a supervised-clinical-practice hour are counted the same way in the underlying state data, but they are not the same kind of training.

Methodology Notes

Averages are computed live by grouping every state-profession requirement record with a non-null education-hours figure by profession, then averaging within each profession. The range column shows the lowest and highest state-reported figure for that profession; large ranges usually reflect states that count differently (for example, whether a degree program's total credit hours are converted 1:1 into "education hours" or only clinical/apprenticeship hours are counted). This ranking reflects hours as currently recorded in our database and does not distinguish classroom hours from supervised on-the-job or apprenticeship hours, both are summed under a single figure per state.

Caveats and Limitations

Reported hours exclude post-licensure continuing education and can differ in how a state's licensing board defines a countable "hour." Some professions license under different names in different states, and some states report a range or a degree requirement rather than a granular hour count, in those cases the requirement record uses the board's own stated figure. Users should verify current requirements with the relevant state licensing board before relying on a specific number. See the full profession directory for state-by-state detail.
