This study compares and examines between consciousness of teachers with different length of teaching about professional development of practical qualities and competencies: 61 novices; 63 teachers with two years teaching experience; 67 teachers with six years teaching experience; 78 mentors. As a result of our examination, we reached following three conclusions: 1) The stably-required practical qualities and competencies have three factors structure and the temporarily-overrated ones have two factors structure. 2) Teachers consider increasingly that the basic competencies of learning instruction, designing children-centered lessons and general educational activities less need to be acquired by novices in a rushed way during their initial stages instead teachers need to acquire them gradually after those stages in association with the length of teaching experience. 3) Teachers tend to give a higher estimate how much novices acquire those competencies with increasing teaching experience and they might consider that they had already learned all basics during their initial stages; including the practical qualities and competencies they actually have acquired in their teaching years.
