q2 · i? · causal · r2

Gain-score analysis of the waiting-list RCT (Table 6: intervention mean gain 25.01, control 18.01, effect size +0.15). The report describes this as "a similar small positive result for NGRTB", consistent with the post-test-only headline.

"An effect size based on gain scores from pre - to post-test also gives a similar small positive result for NGRTB (Table 6)."

• 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
• A second outcome measure, the Progress in English test, suggested RTI may have a negative impact (effect size -0.09), making results mixed and sensitive to what is tested — related
• Sub-group effect sizes for FSM-eligible pupils (+0.48) and boys only (+0.26) were larger but based on very small numbers and deemed not secure — related
