188 Studies On Talk: Five Minutes A Pupil, Worth 6 Months

One pupil, four words, in five minutes of an ordinary lesson — a real transcript, timestamped. That's not a bad lesson, it's most lessons. EEF's Oral language interventions strand — 188 studies, high security — says structured talk adds six months of progress on average, and it works hardest for the pupils who need it most. Not "let them chat more." Something much more specific.

What's covered:

• The Number: +6 months, 188 studies, High security (4/5 padlocks — one lost for lack of independent evaluation)

• What "structured talk" actually means vs the CPD-slide version of "build in more talk"

• The honest cost trade-off: curriculum time is finite, and the evidence doesn't tell you which five minutes to cut

• The disadvantage finding: the more disadvantaged pupils taking part, the more effective the intervention appeared

• Same idea, three rooms: paired talk before hands go up in primary, secondary and a structured choice-board approach in a specialist setting

• Try it today: one question this week, forty-five seconds of paired talk before taking an answer

Actions for consideration:

• Pick one lesson this week and put forty-five seconds of paired talk in front of one question before taking hands up.

• Check whether "talk" in your school means structured, curriculum-tied discussion, or just informal chat time — the evidence is specific to the former.

• Where you're chasing a disadvantage gap, treat structured talk as a targeted lever, not a nice-to-have.

• Don't rewrite your scheme of work — the ask is one question a week, not a curriculum overhaul.

• If cost is a barrier, know the base intervention is very low cost — training pushes it toward moderate, not the approach itself.
