These departments are responsible for different aspects of the examination process. Within each department, there are divisions that consist of units, ensuring efficient coordination and implementation of NECO's activities.
The governing body of NECO is composed of a team of directors and a registrar, with Chair Abubakar Mohammed at the helm. This governing body plays a crucial role in setting policies, overseeing the examination process, and ensuring the smooth functioning of NECO as a whole.
