WHAT NECO STANDS FOR
The National Examinations Council – NECO is a Nigerian Government owned examination body that conducts the Senior Secondary Certificate Examination and the General Certificate in Education in June/July and December/January respectively. These are entry qualification examinations for higher education institutions in Nigeria.
