Abstract: Schools are playing an important role in not only improving knowledge and skills, but also in enhancement of moral and ethical values among school students. The central principle of school education is to inculcate good behaviour in addition to discipline among school students. The present study is carried out in Kundah taluk of the Nilgiris district and survey method is used. 10th standard students are selected randomly from various types of schools and data are collected from eighty six 10th standard students. Mean, standard deviation, t-test and ANOVA test are employed. The results show that significant difference is there among moral reasoning of 10th standard students and their profile except gender. Therefore, teachers should guide 10th standard students to behave morally and ethically and motivate them to adopt personal, cultural, social and moral values effectively. Parents must give favourable home environment to their 10th standard students for enhancing their moral reasoning capacities. Further, teachers should frequently and freely interact with 10th standard students and give advises to them for improving their academic performance, conducts, morality and values.
