Science-of-reading mandates have reshaped the K–12 literacy market, but early-grade gains are beginning to flatten. As districts move beyond initial adoption, vendors face a harder test around implementation, integration, efficacy, and renewal value. This article examines which providers are best positioned as buyers consolidate tools, protect core instruction, and demand clearer evidence that literacy spending improves student outcomes.

I. Why Has the Science-of-Reading Boom Not Produced a Clear Outcomes Boom?
Forty-two states and Washington, D.C. have moved toward evidence-based reading instruction, yet K–2 progress has flattened, especially in first and second grade. The market expanded faster than districts’ capacity to implement what they bought. For vendors, the next phase will be defined less by policy alignment and more by whether products can survive scrutiny around teacher practice, intervention quality, and measurable student growth.
The science-of-reading movement created one of the strongest demand signals in K–12 curriculum in years. States adopted approved-material lists, universal screening requirements, teacher-training mandates, literacy coaching programs, and third-grade reading policies. Districts responded with new core curricula, assessments, intervention tools, tutoring programs, and professional development.
The outcomes have not kept pace with the buying.
