This study examines the impact of parental involvement on students' academic performance, with a particular focus on how different levels of parental support correlate with student achievement. A sample of 300 students from urban and rural schools in Krishna District, Andhra Pradesh, was selected for the analysis. The study investigates various forms of parental involvement, including homework assistance, communication with schools, and fostering educational aspirations. Using quantitative methods such as Pearson correlation and t-tests, the research evaluates the relationship between parental involvement and students’ academic performance, as measured by GPA. The findings reveal a strong positive correlation (r = 0.64) between parental involvement and academic success, with students in areas of higher parental engagement showing better academic outcomes. Additionally, gender-based differences in parental involvement were observed, with female students receiving more parental support. Urban students exhibited significantly higher levels of parental involvement compared to their rural counterparts. These results underscore the importance of increasing parental involvement, especially in rural areas, to enhance students' academic performance. The study offers recommendations for policymakers, educators, and parents to promote active school-parent partnerships and provide resources that support greater parental engagement in students' education.
