Between 1991 and 1995, the percentage of employed workers participating in skill improvement training (SIT) for their current job increased from 30 to 32%. Participation in SIT increased for full- and part-time workers alike. In 1995, participation for a current job was highest among females and individuals in the 35-54 age group. Participation was related to education, occupation, and work status. In both 1991 and 1995, rates of SIT participation were highest among members of the following groups: college graduates; workers in executive, professional, and technical occupations; and individuals employed full time. The 1995 levels of participation in selected occupational groups were as follows: executive, professional, and technical, 49.9% (same as in 1991); sales and administrative support, 29.4% (versus 24.0% in 1991); service, 24.6% (versus 17.8% in 1991); farming, 13.8% (versus 7.0% in 1991); precision production, craft, and repair, 27.4% (versus 21.4% in 1991); and operators, fabricators, and laborers, 19.2% (versus 17.2% in 1991).
