Which beliefs it touches
- C12 Systematic phonics sets a limit on it
Re-analysis of the NRP studies: systematic phonics beat less systematic ("some") phonics by d = .24 or .19 depending on weighting, about half the NRP figure, on pooled reading outcomes; decoding and at-risk readers not separated. Held as open question 16 (2026-10-24), not a narrowing.
