The global demand for technically educated persons is greater than the supply. It is believed that interest and school experience can influence career choice. 624 Slovenian high school students participated in the survey. Exploratory and Confirmatory Factorial Analysis procedures were used to investigate the influence of school and out-of-school-related factors on career aspirations. Predictors of career aspirations in (a) engineering and (b) production and processing occupations in the models were: (1) students' opinions on technical topics, (2) the content of school subject Technics and Technology; and (3) related classroom experiences. The results of the models showed that career aspirations were explained by out-of-school generated opinions on technical topics and not by school-related factors. Boys are more enthusiastic than girls in their career aspirations for technically oriented occupations. This calls for a fundamental revision of the school subject and the corresponding teaching.
