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 i0 At immediate post-test, effect sizes for the three primary literacy measures were small and non-significant (Letter ID 0.08, Word ID 0.05, Word Attack 0.03). → Tracey 2016

q3 · i0 · causal · r2

Intention-to-treat ANCOVA analysis of a two-armed, within-school, pupil-randomised efficacy trial (final analysed post-test sample n = 627, 66 schools). Table 9 reports effect sizes of 0.08 (Letter ID), 0.05 (Word ID) and 0.03 (Word Attack), described as "likely to have occurred by chance".

"While the effect sizes were positive in favour of the SPOKES programme for the primary measures they were small (representing approximately one months’ progress) and were likely to have occurred by chance rather than as a result of participating in the intervention."
