The Public Service Institute of Nigeria Alumni Association (PSINAA) draws its charter from the vision of Public Service Insitute of Nigeria. The Association is not a social organisation. It exists to support the aims and objectives of the PSIN.

Members actively receive continuous education through alumni sessions held all year long. There is also the annual alumni conference held in November which features very high-profile speakers. Active participation in the sessions affords alumni the opportunity to effectively and continually update their knowledge of general management and business subjects.

In addition, there are a variety of discounts from corporate bodies ranging from international airlines and major hotels within and outside the country to internet service providers, bookshops, laundry services, etc. available to financial members of the PSINAA. They also benefit from discounts on all PSIN executive programmes and seminars throughout the year.
