Phonemic Awareness Instruction Helps Children Learn to Read: Evidence From the National Reading Panel's Meta-Analysis
We checked this card's citation and the finding we state against the source's own page or record in October 2026.
What it found
Phonemic awareness instruction had a large effect on phonemic awareness and moderate effects on reading (including comprehension) and spelling, for typical, at-risk and disabled readers. It worked better taught with letters than without, focused on one or two skills rather than many, in small groups, and in programs of 5 to 18 hours rather than longer.
Effect size, as the source reports it: d = 0.86 on phonemic awareness; d = 0.53 on reading; d = 0.59 on spelling.
