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.
q3 i? Pupils who started P4C in Year 5 showed a positive CAT impact, but those who started in Year 4 showed no evidence of benefit; overall the results suggested a small improvement that should be treated with caution. → Gorard et al. 2015

q3 · i? · causal · r2
CAT4 gain-score analysis for both year groups of the randomised trial (3,159 pupils pre-tested; CAT attrition 10%). The report states the combined results suggested a small improvement in CAT scores, but that this should be treated with caution, and that FSM-eligible pupils did not appear to benefit on this outcome.
"Results on the Cognitive Abilities Test (CAT) showed mixed results. Pupils who started the programme in Year 5 showed a positive impact, but those who started in Year 4 showed no evidence of benefit."
