Sample
140 English secondary schools / 25,393 pupils
Population
Year 10-11 pupils in English secondary schools; GCSE Attainment 8 outcome.
Design
The peer-reviewed publication of the EEF Embedding Formative Assessment trial — the SAME trial as Speckesser et al. 2018, not an independent replication. Recorded separately because it reports the sensitivity and complier analyses the evaluation report did not.
Key findings
Peer-reviewed confirmation of the +0.09 at-scale estimate, with 0.11 under sensitivity and complier analyses. The prior-attainment gap narrows while the disadvantage gap does not — the intervention helps low prior attainers, which is not the same as helping poor children.
Genetic confound
Minimal — school-level randomization, national-register outcome.
Replication notes
Same trial as the EEF report; treat the two records as one piece of evidence, not two.
