Cambridge English Grade Boundaries
Complete grade boundaries for B1 Preliminary, B2 First, C1 Advanced, and C2 Proficiency — Cambridge Scale scores, CEFR levels, and what each grade means
Cambridge English Qualifications report results on the Cambridge Scale (0–230) rather than raw percentage marks. Grade boundaries on this scale are fixed and stable year to year — a score of 180 on CAE always means Grade C, regardless of how difficult that exam session was. This page covers the grade boundaries for all 4 main Cambridge English exams: B1 Preliminary (PET), B2 First (FCE), C1 Advanced (CAE), and C2 Proficiency (CPE).
Grade Boundaries by Exam
Select an exam below to see its grade boundary table, Cambridge Scale visualisation, and key insight. Exams are ordered from highest to lowest level (CPE → CAE → FCE → PET) as most users searching for boundaries are preparing for CAE or above.
C2 Proficiency (CPE)
Target level: C2 — Mastery
| Cambridge Scale Score | Grade | CEFR | Certificate Issued? | What It Means |
|---|---|---|---|---|
| 220–230 | Grade A | C2 | Yes | Exceptional — highest level C2 proficiency |
| 213–219 | Grade B | C2 | Yes | Very strong C2 performance |
| 200–212 | Grade C | C2 | Yes | Met C2 standard |
| 180–199 | Level C1 | C1 | No (letter only) | Demonstrated C1 (no C2 certificate issued) |
| Below 180 | Fail | — | No | Below C1 level demonstrated |
A CPE Level C1 result (180–199) means you demonstrated C1 ability but not the C2 level the exam targets. No certificate is issued, but this is equivalent to a strong CAE Grade C performance.
How Cambridge English Sets Grade Boundaries
The Cambridge Scale Explained
The Cambridge Scale is a fixed reporting scale from 0 to 230. All Cambridge English Qualifications report scores on this unified scale, allowing comparison across different exams and levels. The grade boundaries on the Cambridge Scale are fixed — they do not change from session to session. A score of 180 in CAE always means Grade C, regardless of whether that session was harder or easier than others.
Equating and Standardisation
Cambridge uses a statistical process called equating to ensure that the same Cambridge Scale score represents the same level of ability regardless of which exam session was taken. If one paper was slightly harder than usual, the raw marks needed to achieve a given scale score are adjusted accordingly. The result is a fair, consistent measure of ability — unlike raw percentages which would fluctuate with paper difficulty.
Why Cambridge Does Not Publish Raw Mark Boundaries
Because raw mark boundaries vary between sessions due to equating, publishing them would be misleading. A student who scored 65% raw marks in one session may have achieved a different Cambridge Scale score than a student who scored 65% in a different session. Cambridge therefore reports only the standardised Cambridge Scale score, which is directly comparable across sessions.
How Components Combine
Each of the 5 components (Reading, Writing, Use of English, Listening, Speaking) is reported individually on the Cambridge Scale. The overall Cambridge Scale score is the average of the 5 component scores — each contributing equally at 20%. There is no minimum component score requirement; a weakness in one component can be compensated by strength in others.
What the CEFR Levels Mean for Certificates
The certificate issued reflects the CEFR level demonstrated — not simply the exam taken. This is unique to Cambridge: most other English tests do not award a higher-level certificate for exceeding the target level.
- FCE Grade A → C1 certificate issued (not B2), because Grade A demonstrates C1 ability
- CAE Grade A → C2 certificate issued (not C1), because Grade A demonstrates C2 ability
- Level results (e.g. CAE Level B2, FCE Level B1) → no certificate issued, result letter only
What Happens If You Score Near a Grade Boundary?
Cambridge Scale boundaries are exact and hard — there is no rounding, discretionary adjustment, or appeal mechanism that can change a score that is 1 point below a boundary into the higher grade. Understanding what being near a boundary means is essential for deciding whether to appeal, retake, or accept your result.
Just Above a Boundary
If you score just above a grade boundary (e.g. CAE 181 — just above the 180 Grade C boundary), you receive that grade. There is no additional rounding or discretionary adjustment. The Cambridge Scale boundary is exact: 180 is Grade C, 179 is Level B2 with no certificate.
Just Below a Boundary
If you score just below a grade boundary, you receive the lower result. For CAE, a score of 179 means Level B2 — no C1 certificate is issued. This is a hard boundary with no exceptions and no appeal mechanism that can move a 179 to a Grade C.
Enquiry on Results (EOR)
Cambridge offers an Enquiry on Results (EOR) service for students who believe their result is incorrect. Options include a clerical check (verifying marks were added correctly) and a review of marking (re-mark of Writing and Speaking components). EOR requests must be submitted within approximately 3 months of results release. Fees apply and vary by component. If a re-mark changes your score across a boundary, you will receive the higher grade and certificate.
Should You Retake?
If you scored 175–179 on CAE (just below the 180 Grade C boundary), retaking is a viable option — particularly if you can identify which component(s) pulled your overall score down. Unlike IELTS, Cambridge does not offer a one-skill retake — a retake means sitting the full exam again. Use your component breakdown from your Statement of Results to prioritise preparation.
Near-Boundary Scenarios
1 Point Apart — Different Outcomes
Student A — CAE 179
Level B2 result. No certificate issued.
Student B — CAE 180
Grade C. C1 certificate issued.
1 Cambridge Scale point = entirely different outcome. If Student A's component breakdown shows Writing significantly below others, targeted Writing improvement before retaking is the most efficient preparation strategy.
2 Points Apart — Different CEFR Levels on Certificate
Student C — FCE 178
Grade B. B2 certificate issued.
Student D — FCE 180
Grade A. C1 certificate issued.
Both receive certificates, but Grade A opens doors that Grade B does not — universities requiring C1 will accept FCE Grade A but not FCE Grade B.
1 Point Apart — C1 vs C2 on Certificate
Student E — CAE 199
Grade B. C1 certificate issued.
Student F — CAE 200
Grade A. C2 certificate issued.
For most university admissions, both are sufficient. For institutions that specifically require CPE or C2 level certification, Grade A makes a meaningful difference.
Understanding Your Cambridge Component Scores
Your Cambridge Statement of Results shows your overall Cambridge Scale score, plus an individual Cambridge Scale score for each of the 5 components. Understanding this breakdown is essential for interpreting your result and planning any retake.

Worked Example: CAE Component Breakdown
A student with CAE overall 182 (Grade C) might have these component scores:
| Component | Cambridge Scale Score | Vs. Overall | Interpretation |
|---|---|---|---|
| Reading | 188 | +6 | Above overall — strength |
| Writing | 172 | −10 | Below overall — area to improve |
| Use of English | 190 | +8 | Above overall — strength |
| Listening | 185 | +3 | Above overall |
| Speaking | 175 | −7 | Below overall — area to improve |
| Overall | 182 | — | Grade C (C1 certificate) |
This student should focus on Writing and Speaking if retaking — both are below the Grade C boundary threshold (180), meaning they are the components limiting the overall score.
CAE Component Score Interpretation Guide
| Component Score | Grade Level | What It Means for That Component |
|---|---|---|
| 200–210 | A level | Exceptional — C2 ability demonstrated in this skill |
| 193–199 | B level | Strong — confident C1 ability in this skill |
| 180–192 | C level | Solid — C1 ability confirmed in this skill |
| 160–179 | Below grade | B2 level in this skill — area for development |
| Below 160 | Weak | Significant gap at C1 level — priority for retake prep |
A component score below 160 on CAE means that component is pulling your overall score down significantly. If this is Writing or Speaking, targeted preparation in those areas before retaking is strongly recommended.
How Cambridge Exam Levels Overlap on the Scale
The Cambridge Scale deliberately overlaps across exam levels to show that performance near the top of one exam level is comparable to performance near the bottom of the next level up. The diagram below shows all 4 exams plotted on the same 0–230 scale.
FCE Grade A (180–190) = CAE Grade C (180–192)
Both indicate C1 ability. A student who scores FCE Grade A and a student who scores CAE Grade C have demonstrated similar overall English ability. The key difference is that the CAE student demonstrated that ability in a harder exam with more complex tasks and vocabulary. Universities that require CAE Grade C typically also accept FCE Grade A for this reason.
CAE Grade A (200–210) = CPE Grade C (200–212)
Both indicate C2 ability. A CAE Grade A student has demonstrated near-native proficiency in a C1-targeted exam. A CPE Grade C student has passed the C2-targeted exam at the minimum standard. For most purposes these are equivalent, but some elite institutions specifically require CPE.
Two Routes to C1 Recognition
If you are aiming for C1 certification, you have two routes:
Route A — Sit CAE, aim for Grade C or above
Recommended. Grade C (180) gives a comfortable C1 certificate, and Grade B/A provides stronger evidence of C1 or C2 ability. More headroom if you have an off day.
Route B — Sit FCE, aim for Grade A
Technically equivalent (FCE Grade A = C1), but leaves no headroom. A slightly off day would drop you to Grade B (B2 certificate), requiring you to retake a different exam entirely to get C1 recognition.
How Cambridge Grade Boundaries Compare to IELTS and TOEFL
IELTS
IELTS does not have grade boundaries in the Cambridge sense. It reports a band score (0–9 in 0.5 increments) calculated by averaging 4 skill scores. There are no fixed boundaries where the result suddenly changes classification — every 0.5 band is a separate result level. IELTS 6.5 and 7.0 are both valid results accepted at different thresholds.
TOEFL
TOEFL reports a total score (0–120) by summing 4 section scores (0–30 each). Like IELTS, there are no hard pass/fail boundaries built into the test itself — universities set their own minimums. ETS defines performance levels (Advanced/High/Intermediate) but these are descriptive, not certificate-determining.
Cambridge
Cambridge has the most consequential grade boundaries of the three major tests. Crossing the boundary from 179 to 180 on CAE means the difference between no certificate and a C1 certificate. This makes preparation and score targeting more precise — students can calculate exactly what overall and component scores they need and work backwards.
