Community service has been an integral part of Chettinad Hari Shree Vidyalayam since its inception. The term Community Service as the phrase entails, aims at inculcating a sense of kinship between the students and the community that surrounds them.

With this ideal in mind, each class undertakes a project every academic year that allows them to interact with and do their bit to improve some aspect/area of life. The scope of the contribution largely depends on the age of the children. This age appropriate contribution may range from an awareness program for the children themselves or a larger community to a small-scale action plan for improvement. The scope of these programs may vary, but the program focuses on giving children ample time and opportunity to learn about the issue at hand. This is achieved by scheduling periodical slots when all the children under a grade level come together to work under the guidance of their class teachers.

Some of the community service initiatives undertaken are:

• Thanks giving for ayahs and drivers.
• Mission vegetarianism - An endeavor to promote benefits of vegetarianism.
• Click & Care Photo Contest — Raised funds towards scholarship for the less privileged children.
• Hosting Avvai Home Children.
