How do Chinese universities actually calculate GPA?
China has no single national GPA method. An 85 is a 3.0 under the standard four-tier method, a 3.58 on the Peking/CHSI curve, and a 4.0 to an overseas evaluator like WES — which one you use depends on your school and the purpose.
This page is about one country: how Chinese percentage grades become a GPA, how the common methods draw their lines differently, and why one transcript can yield several numbers. Get this straight first.
Standard four-tier: 100-point → GPA chart
| Grade | Percentage range | 4.0-scale point |
|---|---|---|
| Excellent | 90 – 100 | 4.0 |
| Good | 80 – 89 | 3.0 |
| Average | 70 – 79 | 2.0 |
| Pass | 60 – 69 | 1.0 |
| Fail | Below 60 | 0.0 |
The “standard four-tier” method is the one most Chinese university systems use, and the easiest for a quick self-estimate. But it's also the bluntest of several methods; official numbers differ by school (see the comparison below). Note: a 90 is often an A− (3.7) on the US letter scale; the four-tier method rounds it up into the top 4.0 band for simplicity.
How is a Chinese university GPA actually worked out?
Two steps: convert each course's percentage grade to a grade point under some method, then take a credit-weighted average. The formula is GPA = (each course's grade point × its credits) summed, divided by total credits — so high-credit courses pull more weight, and your overall GPA isn't a plain average. The fastest estimate is by band: 90+ = 4.0, 80s = 3.0, 70s = 2.0, 60s = 1.0, fail = 0.
The catch is step one. China has no single national conversion method: some schools use the four-tier rule, some use a curve formula like Peking University's, others use finer 4.3-scale bands or weighted grade points. The same 85 becomes a different grade point when the method changes. So “what's my GPA” really means “under which method.”

This is the heart of it. The standard four-tier method, the Peking/CHSI curve, and an overseas evaluator's cutoffs (WES) each draw the lines differently — so one transcript yields different numbers. It's the clearest proof that China has no unified GPA.
| Score | Four-tier | Peking curve | Overseas (WES) |
|---|---|---|---|
| 95 | 4.0 | 3.95 | 4.0 |
| 90 | 4.0 | 3.81 | 4.0 |
| 88 | 3.0 | 3.73 | 4.0 |
| 85 | 3.0 | 3.58 | 4.0 |
| 80 | 3.0 | 3.25 | 3.0 |
| 78 | 2.0 | 3.09 | 3.0 |
| 75 | 2.0 | 2.83 | 3.0 |
| 70 | 2.0 | 2.31 | 2.0 |
| 65 | 1.0 | 1.70 | 2.0 |
The 88 and 85 rows are where it bites: a full 1.0-point gap on the same score. The Peking curve rewards high scores; the four-tier method is the blunt one; the overseas cutoff (WES) uses 85 as its A threshold and applies only when you're going abroad. One more note: the calculator's "China" option now uses this very Peking / CHSI formula (85 ≈ 3.58), so it lines up with this page; still, a given school may prefer the four-tier method or another scale, so defer to whichever your target school accepts.
The main GPA methods used in China
Standard four-tier
90/80/70/60 → 4/3/2/1 — the method Chinese university systems use most and fine for a self-estimate; it's the main chart above. The downside is bluntness: an 85 and an 89 both score 3.0.
Peking / CHSI curve
A curve formula, GPA = 4 − 3×(100−X)²/1600, that's kinder to high scores (an 85 lands around 3.58). CHSI lists it as a standard method in its transcript-verification reports, which is why it's often called the “CHSI method.”
Refined / weighted variants
Many schools raise the top bar (85 for a 4.0) or switch to finer 4.3-scale bands or weighted grade points, all to separate students more precisely. The exact cutoffs are set by each school's registrar.
Overseas evaluator (WES)
Strictly speaking this isn't a Chinese registrar method but an overseas evaluator's (e.g., WES), used only when you apply abroad and the school requires it: 85+ counts as an A (4.0), a higher bar than at home. The evaluator's course-by-course result is final.
Applying to the US or other schools abroad?
Only then do you convert grades to a US 4.0 scale — a separate evaluation method (usually reported by WES or ECE), not the general method Chinese registrars use. You don't need it for domestic grad-school recommendation or scholarships.

The logic is short — the only real decisions are which scale your transcript uses and which method you need.
1. Check your grade format
Percentage (0–100) or letter bands (优/良/中/及格)? Percentage converts directly; band-only transcripts convert to a range, so confirm the exact cutoffs with your school.
2. Decide which method you need
A self-estimate uses the four-tier method. For domestic recommendation and scholarships, your registrar's GPA rules (a curve or weighted method). For going abroad, an overseas method like WES.
3. Convert each course to grade points
Map every course to its grade point under the method you picked — the same 85 is 3.0 by four-tier, 3.58 on the Peking curve, and 4.0 under the overseas cutoff.
4. Take a credit-weighted average
GPA = Σ(grade point × credits) ÷ Σ credits. High-credit courses move the number more, so your overall GPA isn't a plain average of the grades.
One transcript, several GPAs
Four courses, twelve credits. Same grades, run through several methods — here's how far apart they land.
| Course | Score | Credits | Four-tier | Peking curve | Overseas (WES) |
|---|---|---|---|---|---|
| Calculus | 92 | 4 | 4.0 | 3.88 | 4.0 |
| College English | 85 | 3 | 3.0 | 3.58 | 4.0 |
| Programming | 78 | 3 | 2.0 | 3.09 | 3.0 |
| Politics | 88 | 2 | 3.0 | 3.73 | 4.0 |
| Credit-weighted GPA | 12 | 3.08 | 3.58 | 3.75 |
A 0.6-plus spread on the same transcript. That's why “what's my GPA” has no single answer until you know which method to use.
Roughly what a given GPA signals
The bands below follow the Peking curve as a rough guide; on the blunt four-tier chart the same scores land a tier lower. These are qualitative reads for common situations — exact bars vary by school and program.
3.5 – 4.0 (roughly 85+)
A strong range — competitive for domestic grad-school recommendation, scholarships, and top schools. The closer to the top, the less your GPA is a weak spot, so put your energy into research, competitions, and internships.
3.0 – 3.5 (roughly 80–89)
A solid upper-middle range that keeps most opportunities on the table. It won't stand out or hold you back — lean on research, project experience, and recommendations to round out your profile.
Below 3.0 (roughly 70s)
On the low side. Domestic recommendation and top programs get tougher, but it's not game over — offset it with competitions, research, internships, or test scores, and target a sensible range of schools.
Four things people get wrong about Chinese GPA
“An 85 average is a 3.5 GPA”
No method gives that — four-tier says 3.0, the Peking curve says 3.58. The 3.5 number comes from mixing up scales.
“The CHSI method is the national standard”
CHSI lists the Peking curve as one option, but it isn't a mandatory national standard. Registrars can still use their own methods, and the same score lands differently.
“Switching methods will raise my GPA”
The method is set by whoever's asking, not by you. Domestic recommendation follows your registrar; going abroad follows the school's required evaluator. You can't just pick the flattering one.
“There's one ‘correct’ GPA number”
There isn't. A GPA is tied to a method; a GPA without its method is meaningless. Whatever you report has to match your transcript and the method the recipient requires.

How do Chinese universities calculate GPA?
Two steps: convert each course's percentage to a grade point under some method, then take a credit-weighted average, GPA = Σ(grade point × credits) ÷ Σ credits. The quick estimate is by band: 90+ = 4.0, 80–89 = 3.0, 70–79 = 2.0, 60–69 = 1.0, fail = 0.
Is there a national GPA standard in China?
No. There's no mandated percentage-to-point method; each university sets its own. Common ones are the standard four-tier method, the Peking/CHSI curve, and finer 4.3-scale or weighted methods — so one transcript yields different GPAs.
What are the “Peking” and “CHSI” methods?
They refer to the same curve formula, GPA = 4 − 3×(100−X)²/1600 (0 below 60). Peking University uses it, and CHSI lists it as a standard method in its verification reports — hence the two names. It's kinder to high scores than four-tier, putting an 85 around 3.58.
What's the difference between the four-tier and weighted methods?
Four-tier just maps 90/80/70/60 to 4/3/2/1 with no detail within a band (85 and 89 both score 3.0) — simple but blunt. Weighted or finer methods use more bands or a curve to separate close scores, which is more discriminating but more work. Both then take a credit-weighted average for the overall GPA.
Do I need to convert my GPA to the 4.0 scale to apply to the US?
Usually yes, but that's a final, separate step: evaluators like WES or ECE re-grade each course under their own cutoffs. It isn't the general method Chinese registrars use, and you don't need it for domestic recommendation or scholarships.
Where these methods come from
- NC State institutional grade equivalencies — letter/point cutoffs for Chinese percentages (e.g., 85 = A)
- CHSI (China's official student-records authority) verification method list — the Peking curve and other standard methods
- WES — the letter-grade cutoffs used in overseas credential evaluations (only when applying abroad)
Registrar methods and third-party cutoffs can change; always confirm against your school's rules or the evaluator your target requires.
