Nigeria's 5 Point CGPA System Explained
By Muntasir • Published Sep 18, 2026 • Updated Sep 27, 2026 • Education Planning
Nigerian universities grade you on a 5-point scale, not the 4-point scale common elsewhere. Your CGPA on this scale decides your final degree class.
🎓 A grade = 5 points, F = 0 points
First Class needs a CGPA of 4.50 to 5.00
Second Class Upper runs 3.50 to 4.49
Second Class Lower runs 2.40 to 3.49
The National Universities Commission sets this scale for every accredited university
What the 5-point scale measures
Nigerian universities grade coursework and exams with letters, then convert each letter to a grade point on a 5-point scale. Your Grade Point Average (GPA) covers one semester. Your Cumulative Grade Point Average (CGPA) covers every semester you have completed, and it is the number that decides your final degree class.
The National Universities Commission (NUC) sets minimum academic standards that every accredited Nigerian university follows, which is why the 5-point scale looks almost identical from one campus to another even though each institution writes its own student handbook.
Letter grades and grade points
| Score range | Letter grade | Grade point |
|---|---|---|
| 70-100 | A | 5 |
| 60-69 | B | 4 |
| 50-59 | C | 3 |
| 45-49 | D | 2 |
| 40-44 | E | 1 |
| 0-39 | F | 0 |
Some departments collapse D and E into a single pass grade, so check your own course outline for the exact key. The point values stay consistent across most institutions because they sit inside the NUC benchmark.
GPA versus CGPA
Your GPA for a semester comes from multiplying each course's grade point by its credit unit, adding those totals together, then dividing by the total credit units for that semester. Your CGPA repeats the same calculation across every semester you have sat, from your first session to your current one.
A single weak semester will not sink your CGPA on its own, since the calculation spreads across your entire study record. A strong final year still lifts a CGPA that started low, though the earlier semesters keep pulling the average down because every unit you have taken stays in the total.
Degree classification bands
| Class of degree | CGPA range |
|---|---|
| First Class Honours | 4.50-5.00 |
| Second Class Upper (2:1) | 3.50-4.49 |
| Second Class Lower (2:2) | 2.40-3.49 |
| Third Class | 1.50-2.39 |
| Pass | 1.00-1.49 |
These bands apply broadly across Nigerian universities because they trace back to the same NUC framework, though a few private universities and professional programs such as law, medicine, and pharmacy add extra requirements on top, such as a minimum grade in your final project or passing every core course at first attempt.
Why Nigeria uses 5.0 instead of 4.0
Many countries, including the United States, run degree classification on a 4.0 scale where an A is worth 4 points. Nigeria's 5-point scale gives an extra point of separation between grades, which is one reason a Nigerian CGPA looks different from a US GPA when a student applies abroad and a school needs to convert it.
Ghana's public universities take a different route, scoring coursework as a Cumulative Weighted Average out of 100 rather than as points. None of these scales is more correct than another. Each is a national standard fixed by a regulator, so compare a foreign transcript to its own classification bands instead of assuming a straight point-for-point match.
What changed under CCMAS
The NUC began replacing its older Benchmark Minimum Academic Standards (BMAS) with the Core Curriculum and Minimum Academic Standards (CCMAS ) from 2018 onward, rolling the new curriculum out across disciplines through the early 2020s. The 5-point grading scale and classification bands stayed the same through this change. What shifted was course content and expected learning outcomes per discipline, not how your CGPA gets calculated or how your degree gets classified.
Working out your own CGPA
Your result checking portal usually calculates your GPA and CGPA automatically at the end of each semester. Understanding the manual formula still helps you catch errors, plan how many A grades you need in your remaining semesters, and see exactly how a resit changes your final number.
What your CGPA controls
Your CGPA determines your degree class at graduation, and it often decides whether a postgraduate program admits you without extra conditions. Many master's programs in Nigeria and abroad set a minimum of Second Class Upper for direct admission, while a Second Class Lower or Third Class applicant sometimes needs extra qualifying courses, work experience, or a stronger reference.
Your CGPA also affects awards, scholarships, and eligibility for programs that favor higher grades, and it matters to employers who screen graduate applications by degree class before an interview.
