Findings from a study of International Baccalaureate and general-education students indicate that IB students have lower maladaptive perfectionist tendencies and higher adaptive perfectionist tendencies than general education peers. The trends for adaptive and maladaptive perfectionism differed from grades nine through twelve for IB and general education students, such that maladaptive perfectionism appears to increase with age while adaptive perfectionism decreases for IB students only. Among the sample of IB learners, results indicated statistically significant positive correlations between anxiety and maladaptive perfectionism, global life satisfaction and adaptive perfectionism, and adaptive perfectionism and academic achievement.
