This study tried to examine performance of a chemistry teacher within the context of the special area competencies of chemistry teachers. The method proposed to evaluate the performance of the chemistry teacher consists of three steps. In the first step, the special area competencies of the chemistry teacher were converted into the model estimated by the Analytic Hierarchy Process (AHP) technique. In the second step, the consistency of the local weights of the competencies and pairwise comparisons in the AHP model were determined. In the final, the performance of the chemistry teacher was determined by self-evaluation on the basis of these competencies. Among the competency areas, the relative importance of knowledge in the area of chemistry was found to be higher than that of chemistry literacy. Another finding was that, on the basis of special area competencies, performances of chemistry teachers can be evaluated more objectively with a self-evaluation approach using the AHP technique.
