Self-concept is the sole perspective from which one can understand an individual's behaviour. Academic performance is a complex student behavior and underlies several abilities, e.g., memory, previous knowledge or aptitude as well as psychological factors such as motivation, interests, temperaments or emotions. Home-environment or family environment refers to climate prevailing in the home, which varies from culture to culture, society to society and family to family. In this study attempt has been made to find a relationship between self-concept and home-environment with academic achievement in mathematics and also to find the interactional effect of self-concept and home-environment on academic achievement in mathematics.
