The National Examination Council (NECO) is an examination body in Nigeria that is responsible for conducting the Senior Secondary Certificate Examination (SSCE) and the General Certificate in Education (GCE). The SSCE is held in June/July, while the GCE takes place in November/December.
NECO was established in April 1999 by Abdulsalami Abubakar, who served as the former Head of State of Nigeria. One of NECO's notable achievements is that it was the first federal organization in Nigeria to offer subsidized registration to academic candidates, making it more accessible for students to participate in the examinations.
Under the leadership of Abubakar M. Gana, who was appointed by the President in accordance with section 9(1) of NECO's establishing Act, the organization operates through six departments, each headed by a director. 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.
NECO's primary focus is to conduct fair and credible examinations that assess the knowledge and skills of secondary school students in Nigeria. By providing a standardized and recognized certification, NECO plays a vital role in the education system of the country, facilitating the transition of students to higher education or employment opportunities.
