Abstract: Based on the dichotomy and trichotomy of achievement goal，according to the dimensionality of competence classification— definition and valence of competence , Pintrich & Elliot et al proposed the quartation including mastery approach goal, mastery avoidance goal, performance approach goal, performance avoidance goal. Mastery approach goal focused on mastering new knowledge and enhancing compentence. Mastery avoidance goal focused on avoiding not accomplishing the task or not losing one's knowledges and capabilities. Performance approach goal focused on being superior and better than others. Performance avoidance goal focused on avoiding looking stupid or dumb in comparison to others. The experimental studies indicated that the proposition of new classification not only perfected the classificatory study about achievement goal but also offered the theoretical basis for enhancing achievement of individuals.

Key words: achievement goal, quartation, mastery avoidance goal
