Zero Months: 58 EEF Studies On Setting And Streaming

Zero months. Not a small gain, not "modest for some" — the EEF Toolkit's own average for setting and streaming, across 58 studies, is nothing. A setting coordinator and a form tutor autopsy the promise (teach to the top, protect the bottom, everyone wins) against what actually happened: a small negative effect on low-attaining pupils, and a structural risk of lower expectations, misallocation and less experienced staffing following disadvantaged pupils into lower sets.

What's covered:

• The Number: 0 months average impact, 58 studies, evidence security rated "Very limited" — the weakest band the Toolkit uses

• The promise vs the autopsy: teach-to-the-top-protect-the-bottom vs a small negative effect specifically on low-attaining pupils

• The structural risk: lower teacher expectations, misallocation of disadvantaged pupils to lower sets, less experienced staffing in those sets

• Try it today: check your bottom set's staffing against your best timetable slot, and ask one pupil what they believe the set says about them

Actions for consideration:

• Check whether your bottom set's staffing is a deliberate choice or a default outcome of timetabling — don't assume it's neutral.

• Ask a bottom-set pupil, directly, what they believe the set says about their ability — not just what mark placed them there.

• Don't treat "setting helps everyone" as self-evidently true — the Toolkit's own average is zero, and the harm is specific and named.

• If you set, own the disadvantage-compounding risks explicitly (expectations, misallocation, staffing) rather than assuming the policy is neutral by default.
