The National Examinations Council has released the Senior School Certificate Examination results.
This was disclosed by the Registrar, Professor Godswill Obioma while speaking at the NECO headquarters in Minna, Niger State.
The results show a two per cent increase of candidates who made five credits and above in all subjects.
The Registrar further said that four schools in Adamawa, two in Kaduna, two in Kastina, two in Niger, one in Taraba and one in the FCT were derecognised by the Council for engaging in mass cheating.
He said the Council also blacklisted 24 supervisors who engaged aiding and abetting, connivance with non-candidates to write answers on chalkboards and poor supervision.
