Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? FSM-eligible pupils showed an effect size of +0.48 and boys only +0.26, but the evaluators judged these sub-group results insecure due to very small numbers. → Gorard et al. 2014

q2 · i? · causal · r1
Sub-group analyses of the NGRT post-test in the same trial (FSM-eligible n=96, +0.48; boys only n=210, +0.26). The report warns these "show larger effect sizes" but are "based on very small numbers" and not secure; no ratings are given for sub-group analyses.
"Even further caution must be take n when reading the results for specific sub -groups of pupils such as boys only and pupils eligible for free school meals . These show larger effect sizes but these results are based on very small numbers, and are therefore not deemed secure."

- RTI showed a small positive headline effect of +0.19 on the New Group Reading Test, but the spoilt trial means it should not be taken as indicative of impact — related
- Fresh Start showed positive progress results for FSM-eligible pupils and for all pupil sub-groups, though these findings are less secure — related
- FSM-eligible pupils made around five additional months' progress under TDTS (effect size +0.38), though this finding has lower security — related
- FSM-eligible pupils receiving ReflectED made an average of two months' additional progress in maths, a result the report flags as less secure than the findings for all pupils — related
