Nigeria has practiced many systems of education. The current system is simply known as the 6-3-3-4 system. It is patterned after the system of education in the United States of America.
The 6-3-3-4 System simply means:
6 years of compulsory primary education
3 years of junior secondary school (JSS)
3 years of senior secondary school (SSS)
4 years of university education
The first nine years, that is the 6 years of primary education and the 3 years of junior secondary education, is called basic education and is compulsory for every child. Upon the completion of the 6 years of primary education, students would sit and write the Common Entrance Examinations to qualify for enrollment into a Junior Secondary School (JSS).
