The purpose of this study was to gain insight into the development of student knowledge in pre-vocational secondary education schools which differ in the manner and extent to which they have implemented characteristics of competence-based education. The implementation of these characteristics was examined using a teacher questionnaire and the development of knowledge was investigated using concept mapping. The results showed that students developed slightly more knowledge in learning situations with fewer characteristics of competence-based education. The organisational characteristics of the learning situations were further found to be distinctive for the development of knowledge. (Contains 2 figures, 9 tables, and 1 footnote.)
