In a previous series of studies, a model of comprehensive competence-based vocational education (CCBE model) was developed, consisting of eight principles of competence-based vocational education (CBE) that were elaborated for four implementation levels (Wesselink et al. "European journal of vocational training" 40:38-51 2007a). The model thus consisted of 32 cells, all defined by text. It was developed to provide study programme teams working in vocational education with an instrument to assess the actual and desired "competentiveness" of their study programmes. "Competentiveness" refers to the extent to which study programmes are based on the principles of CBE that we formulated. The model is an instrument for analysing the alignment of study programmes with the defining principles of CBE and clarifying programme teams' intentions, i.e. the extent to which they wish to achieve higher levels of implementation of the different principles. This article presents the results of two studies, the aim of which was to identify adjustments the teachers felt were necessary to make the CCBE model a valid instrument for assessing the actual and desired "competentiveness" of their study programmes. In study A, 57 teachers evaluated the model during focus group discussions, resulting in a revised CCBE model consisting of ten principles for five levels of implementation. In study B, 151 teachers completed a questionnaire to evaluate the comprehensibility of the revised model. The study showed that teachers understood and interpreted the revised model as intended, were able to position their study programmes by using the revised model and that the content validity of the revised model was good.
