A study compared developments in size of apprenticeship programs and changes in the distribution of apprentices over occupational categories in Ireland, Scotland, and the Netherlands during the last 2 decades. Data were from the "time-series" school leavers' surveys database. Findings indicated, toward the late 1990s, Irish apprenticeship was almost exclusively limited to skilled manual occupations and to crafts and related trades. The Scottish apprenticeship system was also rather "focused," but to a lesser extent. The Dutch apprenticeship system covered a broad array of occupations; only one-third of all apprentices were in skilled manual jobs. Occupational differences were smaller in the early 1980s. Apprenticeship became somewhat more limited to crafts or skilled manual jobs in Ireland and significantly less limited in Scotland, where apprentices appeared in service and market sales occupations in the early 1980s and in clerk jobs in the early 1990s. In Ireland, apprenticeship ceased to be the main route to skilled blue collar jobs. The structure of the Scottish youth labor market was very stable in comparison with Ireland, but the division of labor among apprentices, trainees, and "normal workers" fluctuated heavily in Scotland from 1979-95. The percentage of missing values for Dutch apprentices on the EGP variable was too high and too fluctuating over time to permit data analysis.
