Last Updated on December 10, 2020 by Ope Quadri

Grading system in Nigerian secondary school may not be the same as it is in UK, United States and other countries around the world. In this post, you’ll see SUBEB grading system in Nigeria.

Grading in education is the process of applying standardized measurements of varying levels of achievement in a course.

However, every country tries as much as possible to implement the United Nations Educational, Scientific and Cultural Organization (UNESCO) stipulated standard.

In this post, we’ll tell you SUBEB approved grading system in Nigerian secondary schools.


What is SUBEB in Nigeria? 

SUBEB means State Universal Basic Education Board. It’s an offshoot of the Federal Government’s Universal Basic Education (UBE) to enhance the efficiency of education standard in Nigeria.

So, all the 36 states in Nigeria including the FCT have their own education board to adequately implement education policies in their jurisdiction. SUBEB also have its grading system.

“State Universal Primary Education Board (SUBEB), an offshoot of UBEC in the states, is established to address the inequality in educational opportunity at the basic level and improving the quality of its provision.

“The programme was introduced by the Federal government to remove distortions and inconsistencies in basic education delivery and reinforce the implementation of the National Policy on Education as well as to ensure access, equity and quality of basic education throughout the country.”Adetoun & Kolawole

Osun State, South-West, Nigeria under the administration of Governor Rauf Aregbesola started the use of Grade in the state a few years back.

So, one might want to ask…

What is Grade 12 equivalent in Nigeria?

That’s simple, though it could be confusing to someone who isn’t familiar with foreign standard of education.

The simple explanation goes thus:

Pupils spend six years in Primary School (Pry 1 to Pry 6), which some people prefer to call elementary education.

Objectives of primary education in Nigeria

“Primary education should provide the learner with opportunities to: acquire literacy, numeracy, creativity and communication skills. enjoy learning and develop the desire to continue learning.”

This is followed by six years of secondary school: three years in Junior Secondary School (JSS1, JSS2 and JSS3)


  • JSS1=Grade 7;
  • JSS2=8th Grade
  • 9th Grade=JSS3.

The rest is three-year in Senior Secondary School, consisting of SS I, SS 2, and SS 3


  • SS 1= 10th Grade
  • SS 2= 11th Grade
  • SS 3= 12th Grade.
