- C12 Systematic phonics sets a limit on it
Multilevel re-analysis of the NRP studies: systematic versus "some" phonics d = 0.123, not significant (p = .183), on pooled reading outcomes (numbers from the authors' 2008 follow-up; rival re-estimate 0.183, p = .042). Held as open question 16 (2026-10-24), not a narrowing.
