Abstract
This paper attempts to formulate specific criteria for measuring competence and progress in philosophy, specifically in children. In detailing these criteria, previous evaluation criteria for philosophical thinking in children are described and three main tendencies of philosophical thinking are identified: those involving analytical and reasoning qualities, those dealing with ambiguities or borderline explorations, and those stressing contact with real life experience. Finally, the authors address problems relating to the recognition of these qualities and catalogue seven groups of indicators that help to identify (or exclude) them.
