The purpose of the study was to compare the stress level between government and private school students in Delhi. The study was delimited to the age group 15 to 17 years. By applying simple random sampling 200 students (100 govt. + 100 private) were selected, constituting 50 male and 50 female students each from both government and private schools. The study was confined to the North Delhi area only. The variable for the study was stress; Student-life Stress Inventory modulated by Gadzella (1991) was used for the collection of data. The statistical techniques employed were descriptive statistics and ‘t’ test. The result of the study showed that 70% of the students were having a low-stress level and 30% of the students were having moderate stress levels and none of the students was experiencing a high-stress level. The results for ‘t’ test employed showed a significant difference between government and private school students for stress level, as the calculated value was found 4.19 against the tabulated value of 1.96. The mean value for stress levels of government and private school students were 1.1 and 1.45 respectively. A significant difference was also found for male and female students stress levels, as the calculated value was 2.55 against the tabulated value of 1.96. The mean values for male and female students were 1.123 and 1.345 respectively. It was concluded that students from both government and private schools experienced stress at different levels and there was a significant difference in the stress levels of government and private school students. The difference may be due to the level of exertion (Physical, Physiological and Psychological) being given to the students in private schools as compared to government schools.
