Environment is capable in providing mankind with everything he requires, not just for self-sufficiency, but also for a comfortable life. Everything that is around us is known as the environment. It might be both living and non-living entities. Physical, chemical, and other natural forces are also included. Conserving our natural resources is a prime concern for us. Environmental education, whether formal or informal, does have the actual purpose of creating awareness among people. The main aim of the purposed investigation was to find out the environmental awareness level of higher secondary school students in relation to their gender and locality. For conducting this study, a sample of 240 higher secondary school students of government schools was selected by adopting random sampling technique. The Environment Awareness Ability Measure (EAAM) developed and standardized by Dr. Praveen Kumar Jha (1998) was employed to gathered data from government higher secondary school students of district Solan of Himachal Pradesh. Mean, S.D. and t-test were used for analysis of data. It was found in the study that higher secondary school students do not show any large difference in environmental awareness in relation to their Gender and Locality. It was revealed that the students are well aware of their environment with respect to their surroundings and almost facing the same type of environment problems.
