Academic stress is a growing concern among adolescents, particularly during high school years when academic demands and expectations intensify. This study aims to explore and compare the levels of academic stress experienced by high school students across different types of school management—namely, government, government-aided, and private institutions. The research focuses on identifying whether the administrative and educational practices of these management types influence the stress levels of students. A stratified random sampling method was employed to select a representative sample of high school students from each school type. Data were collected using a standardized academic stress scale, and statistical techniques such as ANOVA were used to analyze the differences across groups. The findings revealed significant variations in academic stress levels among students based on the type of school management, with students from government institutions reporting higher stress levels compared to their peers in private and aided schools. These results highlight the need for school administrators and policymakers to implement targeted stress-reduction strategies tailored to the specific pressures associated with each management type. The study underscores the importance of creating a balanced academic environment that prioritizes student mental health and well-being.
