How are these exams compared?

Conversions anchor on the CEFR scale, which all four exams publish an alignment to, supplemented by the official ETS/IELTS concordance. Because the tests measure slightly different skills, the result is a close band, not an exact one-to-one number.

How accurate is IELTS to TOEFL conversion?

ETS and IELTS jointly published a concordance, so IELTS-to-TOEFL mapping is well-grounded. For example IELTS 7.0 corresponds to roughly TOEFL 94-101. The tool uses these official ranges and returns a representative mid-point.

Is the Duolingo conversion reliable?

Duolingo publishes its own IELTS and TOEFL comparison tables, so conversions are based on the test maker's figures. Accuracy is reasonable around the middle of the range but loosens at the extremes, where fewer concordance data points exist.

Why doesn't my converted score match exactly what a university lists?

Institutions set their own admission thresholds and may be stricter or more lenient than a pure concordance. Always check the specific score each program requires; use this converter to see whether your result is in the right neighbourhood.

Can I convert between Cambridge and IELTS?

Yes. The Cambridge English Scale and IELTS both map to the CEFR, so a Cambridge Scale score of about 185 aligns with roughly IELTS 6.5 (CEFR B2). The converter routes both through the shared CEFR anchor.

What is the Language Exam Score Converter?

Enter a score from one English proficiency exam — IELTS, TOEFL iBT, Cambridge (B2/C1/C2) or Duolingo English Test — and convert it to the equivalent on the other tests using published concordance and CEFR alignment tables. It runs free in your browser on Gera Tools, with nothing uploaded.

Language exam score converter

When a program accepts several English exams, you need to know whether your IELTS, TOEFL iBT, Cambridge or Duolingo score clears the bar on a different test. This converter anchors all four exams on the CEFR scale and the published IELTS-TOEFL concordance to give you an approximate equivalent on each.

How it works

Each exam reports on its own scale: IELTS in 0.5 band steps (0-9), TOEFL iBT as a 0-120 total, the Cambridge English Scale roughly 140-230, and the Duolingo English Test 10-160. The converter places your input score into a CEFR band, then reads across a concordance table to the representative score on every other exam.

IELTS 7.0  ≈ TOEFL 94-101 ≈ Cambridge ~191 ≈ Duolingo ~120 ≈ CEFR C1

Conversions are bands, not exact equalities, because the exams test slightly different skills. The tool returns a representative value and the shared CEFR level.

How each exam is structured

Understanding what each test actually measures helps you read the conversion correctly:

IELTS (International English Language Testing System) — scored 0–9 in 0.5 increments, with separate band scores for Listening, Reading, Writing, and Speaking averaging to the overall band. University admissions typically require 6.5–7.5. There are two versions: Academic (university entry) and General Training (work/migration). This converter works with Academic IELTS scores.

TOEFL iBT (Test of English as a Foreign Language) — scored 0–120, split across four sections of 0–30 each. Stronger on reading and listening than IELTS because it is delivered entirely via computer with no face-to-face speaking component. The most widely accepted exam at US universities.

Cambridge English Scale — runs approximately 140–230, with qualifications at fixed score thresholds: B2 First around 160–179, C1 Advanced around 180–199, C2 Proficiency around 200+. A Cambridge qualification does not expire once awarded, which is an advantage over IELTS and TOEFL (valid 2 years).

Duolingo English Test (DET) — scored 10–160, taken online at home, results in 48 hours. Broadly accepted by over 5,000 institutions but with narrower acceptance than IELTS or TOEFL. Strong at the lower CEFR levels; concordance data becomes thinner at very high scores.

Common admission thresholds

These are illustrative ranges used by many programmes — always verify with the specific institution:

CEFR level	IELTS	TOEFL iBT	Cambridge	Duolingo
B2 (Upper Intermediate)	5.5–6.0	72–87	160–179	95–110
C1 (Advanced)	6.5–7.0	88–101	180–199	110–125
C2 (Proficient)	7.5–9.0	102–120	200+	130–160

Notes

The IELTS-to-TOEFL figures come from the official ETS/IELTS concordance, and Duolingo’s comparisons come from Duolingo’s own published tables, so the mappings are grounded in test- maker data. Even so, universities set their own thresholds — some stricter than a plain concordance — so use the result to check you are in the right range, then confirm the exact score your target program requires. All computation is local in your browser.
