Singapore vs Thailand Grading System

How does the Singapore grading system work?

NUS and NTU use a 5.0 CAP scale. SMU uses a 4.0 GPA. Singaporean degrees are highly regarded internationally.

⚠️ NUS/NTU use 5.0 CAP, SMU uses 4.0 GPA. Check which university issued your degree.

How does the Thailand grading system work?

Thai universities use a 4.0 GPA scale aligned with US conventions.

Do Singapore and Thailand mark to the same standard?

No — and it is the difference in marking culture, not the arithmetic, that makes a direct comparison mislead. Here is how each country actually uses its own scale.

What a good grade means in Singapore

Singaporean degrees are highly regarded internationally, and the grading is demanding: NUS and NTU run bell-curve moderation, so grades reflect standing within a strong cohort rather than an absolute mark. That makes a CAP of 4.0 a genuinely good result even though, mapped to US letters, it sits at a B+ rather than an A. The honours class is the signal to lead with abroad, because Highest Distinction and Distinction are understood in Commonwealth terms in a way a raw 5.0-scale number is not.

What a good grade means in Thailand

The 4.0 scale converts cleanly, so Thai transcripts need little translation — the substance is in the honours conditions rather than the number. First-class honours in Thailand normally requires not only a high GPAX but completion within the standard duration and no repeated subjects, which makes it a stronger signal than the average alone conveys. State the honours designation, because an admissions office abroad will read the GPAX at face value and miss the rest.

Will a grade from Singapore get you into Thailand?

We do not yet hold published entry requirements for Thailand, so we do not compare your grade against a bar we cannot cite. The conversion above still tells you how your result reads in Thailand terms.

For NUS/NTU (5.0 CAP): 4.0–5.0 (Honours HD) → approximately 4.0 US GPA.

Mistakes specific to Singapore grades

• Reading a CAP of 4.0 as equivalent to a US 4.0. On the 5.0 scale it corresponds to roughly a B+ average — a good result, but not a perfect one.
• Quoting a CAP without saying whether the scale is 5.0 (NUS, NTU) or 4.0 (SMU). The two are not interchangeable.
• Omitting the honours class. Highest Distinction and Distinction translate far better internationally than the underlying number.

What should you do next, applying from Singapore to Thailand?

1. Check the course, not the country. Entry requirements are set per programme and revised every cycle. We hold no published national bar for this destination, so the course page is the only figure that binds.
2. Check whether an evaluation is even required. Unlike the US and Canada, Thailand universities commonly assess foreign transcripts in-house. Confirm on the course page before paying for a report you may not need.
3. Get your documents moving early. Universities normally require your transcript sent directly by your institution rather than as a copy from you, which takes longer than most applicants expect.
4. Read both systems in full. How Singapore grading works · How Thailand grading works

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.

Honours degree

A bachelor's degree that includes a higher-level final year or research project — in Australia, South Africa and New Zealand it is often an extra year, and master's entry can depend on it.
