Direct answer

Speaking stuck at 6.5 means you communicate well but one or two criteria stay at Band 6, usually Part 3 depth, lexical precision, or fluency under follow-up pressure. Grammar and pronunciation at 6 can coexist with fluent Part 1 and shallow Part 3. The fix is not more idioms, it is sustained positions with reasons and examples on abstract questions. See shallow Part 3 and Band 6 to 7 transition.

Typical 6.5 Speaking profile

Even pace, missing stress on key words, and answers that ignore question focus overlap false fluency in Speaking.

Trigger Strong Part 1; weak Part 3 development

Symptom Display vocabulary; imprecise collocations

Score leak One criterion at 6 pulls overall to 6.5

6.5 profile vs Band 7 target

6.5 trap	Developed answer
Five points, zero reasons	One claim + because + for example
Fillers and repetition to buy time	Clear verbs that carry the argument
Never answers the examiner follow-up	Stays on one idea until developed

6.5 to 7 Speaking drill

1. Question-first rule

State one clear claim in sentence one.

2. One reason, one example

Add because, then one concrete example.

3. Random follow-up pairs

Record 45-second answers; cut any sentence without a job.

Key takeaways

6.5 is often Part 3 depth, not accent or grammar alone.
One developed idea beats five headlines.
Developed answers beat downloaded Band 8 scripts.
Part 3 follow-ups expose shallow lists fast.

FAQ

Often one criterion away, but Part 3 depth is the usual leak, not more idioms.

Only if other skills meet target, fix the 6 criterion first with blind Part 3 drills.

Many need four to eight weeks of Part 3-only depth work, not another full mock marathon.
