A phonics trial helped older readers, but spelling did not budge

An SRI evaluation released September 25 found that a structured phonics program improved two reading measures for students in grades 4 through 8, an age group often left out of foundational reading research. The same study found no spelling advantage, a useful brake on claims that one method fixes every literacy skill.

Phonics after the early grades

The evaluated program, Sounds-Write, starts with speech and maps sounds to print. SRI describes it as a structured linguistic phonics approach that does not center syllable-type rules or memorized sight-word lists. One goal is helping students flexibly decode unfamiliar, multisyllabic words.

The study combined randomized and quasi-experimental designs across two districts, three teacher cohorts and nine schools. It covered 30 teachers and 448 students, comparing the program with the literacy instruction schools ordinarily provided. Those design details matter because evidence about phonics for older students is much thinner than evidence about beginning readers.

According to SRI, students taught the program gained 6.4 percentile points on word reading and 5.6 points on sentence-reading efficiency relative to peers. The organization says the gains appeared across socioeconomic, English-learner and individualized-education-plan groups rather than only among advantaged students.

The result the headline could hide

Spelling did not improve more than under typical instruction. SRI suggests inconsistent implementation of some components or benefits received by comparison students as possible reasons, but those are explanations to investigate, not established causes. The null result also shows why it matters to measure a skill separately rather than assume reading gains imply spelling gains.

Teachers reportedly implemented core rule-free features with strong fidelity but were less consistent with more demanding parts. Sixty-nine percent rated the program more effective than prior phonics approaches, and 63% planned to continue using it. Middle-school teachers wanted faster pacing for students who had encountered phonics before.

These findings support a narrower conclusion than a universal prescription. A particular speech-to-print program appeared to help reading in this sample of older learners. The report does not establish that it will work identically in other districts, for every student or at any pace. Nor does it show that spelling can be ignored.

The next useful test is whether the reading gains persist, transfer to broader comprehension and can be reproduced in more schools without losing the program's most demanding elements.
