An additional meeting was held by the AHP committee to develop the pairwise comparison matrices based on the discussions, impressions and judgments drawn from the group decision. Pairwise comparisons were first made for the basic qualification, oral examinations and written examinations (hierarchy level 2). Then the relative importance priorities of the respective secondary-criteria (hierarchy level 3) were derived. The pairwise comparison matrices for the AHP criteria and secondary-criteria are given in Table 2 and summarized in Table. 3.
