CEFR to IELTS Band Mapping Explained

CEFR · Bands · May 2026

Direct answer

CEFR describes what you can do in real life; IELTS bands describe performance on one high-stakes test. Rough alignments: A2 about 3-4, B1 about 4-5, B2 about 5.5-6.5, C1 about 7-8, C2 about 8.5-9. Classroom B2 does not guarantee IELTS 6.0—exam tasks, timing, and stress compress scores. Use CEFR for course placement; use IELTS bands for visa and university cut-offs.

Common alignments (approximate)

B1 about Band 4-5

B2 about Band 5.5-6.5

C1 about Band 7-8

Why mappings break down

Bands	Mean	Reported
Coursebook B2	Untimed class tasks overestimate exam band
Strong speaking, weak writing	Four skills diverge
Old IELTS score	CEFR profile may have shifted
AI chat fluency	Inflated self-rating without timing

Use both frameworks

Timed mock

Place yourself with a full four-skill mock, not classroom level alone.

Visa rules

Check cut-offs in IELTS bands, not CEFR letters on forms.

B2 feedback

See AI feedback for B2 speakers for delivery differences.

Practice fix

Match your mock band to CEFR only after timed four-skill results.

Key takeaways

Overall = mean of four skills, then round.
No skill is weighted more than another.
Minimum per-skill rules trump a strong overall.
One +0.5 skill gain moves the mean by 0.125.

FAQ

No—B2 spans roughly 5.5-6.5 depending on skill and performance on the day.

App levels measure different tasks; treat them as direction, not a certificate.

IRCC uses CLB tied to IELTS bands, not CEFR labels on forms.
