What is the validity period of a NISM certificate?

NISM certificates are generally valid for 3 years from the date of passing.

To stay certified, you renew before expiry either by attending NISM’s Continuing Professional Education (CPE) programme within the window allowed before the certificate expires, or by passing the exam again. Check the exact rules for your module on NISM’s website, and track your renewal date if your job requires the certificate.
