Professionalism in procurement has been a long-standing challenge in Nigeria, making the professionalization of procurement functions across both the public and private sectors essential. The development of the Nigeria Public Procurement Professional Certification Framework (NPPCF) aims to address this need by clearly defining and integrating a set of key competencies — comprising knowledge areas, business processes, interpersonal skills, and attitudes — into public procurement practices. This will enhance value for money in public expenditure and strengthen procurement systems across the country. The NPPCF is anchored in the provisions of the Public Procurement Act of 2007, aligning with its regulatory framework to ensure effective oversight and bolster procurement processes within Nigeria's Ministries, Departments, and Agencies (MDAs). The framework is applicable to procurement professionals across both the public and private sectors, establishing a unified approach to improving the professionalism of procurement activities.
