Eligibility for membership in the Nath Valley School Alumni Association extends to any individual who has attended Nath Valley School at any time, provided they have graduated from 12th standard, regardless of the school from which they graduated. For instance, an individual who studied at NVS but completed their 12th standard at a different institution is still eligible to join the alumni association.

Additionally, all teachers who have been associated with Nath Valley School are considered members of the alumni association.

The Nath Valley Alumni Association (NVAA) hosts its annual meet on the third Sunday of December, following the school's Annual Day. This event underscores the significance of alumni in the school's legacy, as they are as crucial to the institution's identity and growth as its current students. These meets are characterized by dynamic exchanges of ideas, engaging discussions on various topics, and a host of innovative games organized by Mr. Dass or the office bearers, fostering a joyous atmosphere reminiscent of school days.

These alumni gatherings offer former students a chance to contribute to the school's ongoing development, either through financial support or innovative ideas. Nath Valley School benefits immensely from its extensive alumni network. A recent example includes a member of the Commonwealth connecting with Mr. Dass, facilitated by an alumnus. This growing network continually introduces fresh perspectives and ideas to the school.

Looking forward, the Association plans to enhance alumni engagement through regular workshops and programs. These include talks by successful entrepreneurs and businessmen, sports events, and other activities, aimed at strengthening the alumni community and fostering greater collaboration in the years ahead.
