The National Examinations Council (NECO) has released the internal Senior Secondary School Examination (SSCE) results with a two per cent increase of candidates who made five credits and above in all subjects.
The Registrar, Professor Godswill Obioma, announced these at the NECO Headquarters in Minna.
The council also decertified 12 schools for their involvement in mass cheating and whole school cases of malpractice.
He said the schools decertified include 4 schools in Adamawa, 2 in Kaduna, 2 in Kastina, 2 in Niger, 1 in Taraba and 1 in FCT.
He said that 24 supervisors were blacklisted for various offences ranging from poor supervision, aiding and abetting, connivance with non-candidates to write answers on chalkboards.
