Self-esteem is one of the most important components of human development. It encompasses the overall beliefs about own strengths and weaknesses which impacts upon individuals’ attitudes, behaviours, thoughts, actions, and emotions. For this paper, the researchers conducted a study to examine the level of self-esteem of the post-graduate students. The researchers adopted descriptive survey method where stratified random sampling technique was used to select the sample. The sample of the study includes 100 post-graduate students of Sidho-Kanho-Birsha University, Purulia. The ‘“Rosenberg Self-Esteem Scale”’ (RSES, 1965) was used to assess the level of self-esteem of the post-graduate students. For data analysis and interpretation, statistical measures like Mean, Standard Deviation, t-test were calculated for the data obtained from the survey. Finally, the study findings revealed that though there was no significant difference between the male and female students of both Arts and Science stream, but it was observed that there was significant difference between the post-graduate students of Arts and Science stream in respect of their self-esteem.
