The circular relaxes the certification requirements for Persons Associated with Investment Advice (PAIA) who perform only sales and other non- core services. It has introduced a lighter certification requirement for staff such as sales personnel, relationship managers, and others who interact with clients but are not directly involved in providing investment advice. Such personnel must now pass the NISM Series-XXV-B: Persons Associated with Investment Advice (Sales and Other Non-Core Services) Certification Examination. PAIA involved in investment advisory functions will continue to require the NISM Series-X-A (Level 1) and Series-X-B (Level 2) certifications.
