The highlighted schools morphed from primary schools/Teachers’ Training Colleges into secondary schools before independence. The exact date of metamorphosis of these schools cannot be ascertained, hence the original years of establishment was used in listing them. Primary Schools and Teachers’ Training Colleges that didn’t morph into secondary schools are exempted from the list. Northern Provincial Schools are also exempted because of inadequate information/recorded history. Examples include;
Adamawa Provincial Secondary School (Gen. Murtala Muhammed College), Yola (1920)?!
Katsina Provincial Secondary school (Government College, Katsina) (1930)?!
