This paper demonstrates research activities regarding ontology-based knowledge evaluation in Higher Education. Conceptualization initiatives for educational domain are currently a hot topic and at the same time a challenge. In the paper we demonstrate an adaptive knowledge testing and evaluation system supported by the educational ontology, which helps the students to explore missing knowledge areas and guide them to the material which has to be further studied. The system is the outcome of fourteen higher institutes in Hungary, so we have gathered several experiences during the system test (which was organized and performed by the participating higher institutes and their students), which we highlight in the article. Current phase of the research concentrated to the curricula of the Business Informatics program, as a test environment. We outline our further improvement and refinement also.
