Temperament is defined as that part of the personality which is genetically based. Along with character, and those aspects acquired through learning, the two together are said to constitute personality. The paper aims to study the relationship between temperament and character. The sample comprised of 300 post graduate students selected randomly from Aligarh Muslim University. For collecting relevant information for the present study, the investigator used The Temperament and Character Inventory (TCI) by Cloninger et. al [1994]. The analysis was done by computing the product moment correlation between the two variables. The result showed that the temperament of the post graduate students was found to be negatively but significantly related to their character. The negative correlation between the temperament and character is mainly due to novelty seeking and harm avoidance dimensions of temperament. However, Reward dependence (a dimension of temperament) was found to be positively related to Cooperativeness and Self transcendence (dimensions of Character). Persistence (a dimension of temperament) was found to be positively related to Self directedness and Cooperativeness (dimensions of character). The educational relevance of the findings of the study is discussed.
