🇳🇬 Nigeria Grading System Explained

How does the Nigeria grading system work?

Nigerian universities use a 5.0 CGPA scale — not 4.0. First Class Honours requires 4.50–5.00 CGPA.

Nigerian universities grade on a 5.0 CGPA — a cumulative grade point average where 5.0, not 4.0, is the maximum. Stating the scale is the single most important thing you can do on an international application: a 4.50 read against a 4.0 scale looks impossible rather than excellent.

The NUC (National Universities Commission) sets the classification bands: First Class 4.50–5.00, Second Class Upper (2:1) 3.50–4.49, Second Class Lower (2:2) 2.40–3.49, and Third Class 1.50–2.39.

Many Nigerian transcripts state a percentage instead. Both systems are real and in active use — on the percentage version a First Class is 70% or above — so check which one your transcript actually shows before converting anything.

⚠️ Nigerian universities use a 5.0 scale, NOT 4.0. A 4.5/5.0 is First Class on the Nigerian scale — do not read it as a 4.5 on a 4.0 scale.

What does each grade mean in Nigeria?

What does a good grade actually look like in Nigeria?

Nigerian classification is strict, and it travels better than most applicants expect. A First Class is genuinely rare, and Cambridge's own equivalence table treats a Nigerian First (CGPA 4.5/5, or 70%) as matching a UK First — independent confirmation from a named institution that the classification is understood abroad. A 2:1 is a solid, competitive result for master's applications across the UK, Ireland and Australia, and you should present it as such rather than apologising for the number.

How do WES and other evaluators read grades from Nigeria?

WES maps Nigerian class of degree using classification bands. First Class (4.5–5.0) → approximately 3.7–4.0 US GPA.

WES requires the academic transcript sent directly by your university, plus the degree certificate or a statement of result. Nigerian institutions are often slow to dispatch these, and that delay is the most common cause of missed application deadlines from Nigeria — start months earlier than feels necessary. Check your transcript states the CGPA scale explicitly; if it does not, ask for a covering letter that does.

Is a degree from Nigeria accepted abroad?

Nigerian bachelor's degrees run four years, or five for engineering, law, pharmacy and medicine, which satisfies the 16-year expectation of US graduate schools. Most graduates then complete a year of NYSC (National Youth Service Corps). It is not an academic qualification and does not raise your classification, but it explains a year's gap on your record and is worth stating on an application.

What do people get wrong about grades from Nigeria?

• Letting a university read your CGPA against a 4.0 scale. Always write "4.20 on a 5.0 scale" — never the bare number.
• Converting a percentage as though it were a CGPA. A Nigerian 72% is a First Class; entered into a 5.0 CGPA field it becomes meaningless.
• Assuming your degree certificate or NYSC discharge is enough. Evaluators want the academic transcript, which is a different document.

What grade do you need to study abroad from Nigeria?

Each destination below publishes its own typical entry requirement for a taught master's — a one-to-two-year postgraduate degree made mostly of classes. The last column restates that bar in Nigeria's own grading terms, so you can hold it against your actual transcript instead of converting in your head.

The last column is a double conversion — the destination's bar onto the US 4.0 scale and then onto Nigeria's, so its uncertainty is wider than a single conversion and it is shown as a range for that reason. Treat it as orientation, and check the course page for the bar that actually binds. How this is worked out.

Only destinations whose entry requirement we have read and cited appear here. Several countries publish no numeric bar at all — France admits on the dossier, Japan by entrance examination — and others we simply have not researched yet. An absent row never means “no requirement”.

The last column links the organisations that maintain each country's programme data — we hold none of it ourselves, and none of them can tell you whether you will be admitted. Several countries have no single national directory for postgraduate study at all: master's applications go straight to the university, so the course page is the authoritative source.

How do grades from Nigeria compare, side by side?

Each of these sets Nigeria against one destination in detail — the two grading cultures, the traps specific to that direction, and the converter preset for the route:

• Nigeria vs United States grading system
• Nigeria vs United Kingdom grading system
• Nigeria vs Canada grading system
• Nigeria vs Germany grading system
• Nigeria vs Australia grading system

Applying to the US or Canada? Read the WES credential evaluation guide before you order — choosing the wrong report type is the most common (and costly) mistake.

What do these grading terms mean?

CGPA (Cumulative Grade Point Average)

The same idea as a GPA but covering your whole degree rather than one term — the scale differs by country (India 10, Nigeria 5.0, Pakistan 4.0), so the number alone means nothing without its scale.

GPA (Grade Point Average)

The US way of expressing an overall grade, on a 0–4.0 scale where 4.0 is the top — so a 4.0 is roughly what a 90–100% or a First Class would be elsewhere.

Degree classification

A named band your final result falls into — First Class, 2:1, Distinction — used across the UK, Ireland, Nigeria, India and much of the Commonwealth instead of a single number.

First Class Honours

The top degree classification, awarded to a small minority of graduates — usually 70%+ in the UK and Ireland, or a CGPA of 4.50+ on Nigeria's 5.0 scale.

2:1 (Upper Second Class)

The second-highest degree class, and the grade most UK and Irish master's courses ask for — usually 60–69%.

Credential evaluation

A paid report from an approved company that restates your foreign qualification in local terms, which many US and Canadian universities require before they will assess you.

WES

World Education Services, the most widely accepted credential evaluation company for the US and Canada — it converts your transcript into a US GPA that universities will accept.

Transcript

The official document from your university listing every subject you took and the grade you got — not the same as your degree certificate, and universities abroad want both.
