Yet most literacy instruction still operates as if it’s true.
Reading Reimagined is the result of a five-year effort examining why reading proficiency stalls in the upper grades—and what must change to address it.
Rethinking how students learn to read through Eighth Grade
Slide
For decades, literacy instruction has been shaped by a common assumption: by third grade, students have mastered the foundational skills they need and can independently tackle increasingly complex text.
But literacy outcomes tell a different story. Only about one-third of students read at grade level on national assessments, and results remain significantly lower for many students from historically underserved communities.
Slide
We wanted to understand: Was the common assumption the correct assumption?
Our research says: no. Over the past five years, we’ve revealed a widespread gap in advanced foundational literacy skills among older students—skills required to decode the multisyllabic, morphologically complex words that dominate upper-grade text. When instruction moves away from these skills too early, many students struggle to access meaning from what they read—and their reading success slips.
Slide
Decoding and comprehension are like two wires that must remain connected for the light to go on—and stay on. Reading development shouldn’t end in third grade. It needs to continue from kindergarten through eighth grade as texts increase in complexity.
Through our process of Define, Measure, and Intervene, we’ve clarified the root causes of reading challenges in older students, developed better ways to identify them, and named instructional approaches designed to help students overcome them.
The Story Behind The Research
Why reading proficiency stalls in the upper grades
Slide
Reading Reimagined examined the relationship between decoding and comprehension across grades K–8.
The research confirmed a critical insight:
Decoding is a prerequisite for comprehension.
As text complexity increases in grades 4–8, students encounter thousands of new multisyllabic and morphologically complex words each year. Early decoding skills alone are not sufficient to support this transition.
Slide
In partnership with researchers, educators, and school districts, Reading Reimagined has found:
• Many students in grades 4–8 lack the advanced decoding skills needed to independently access grade-level text.
• Decoding challenges increase as words and sentences grow more complex.
• Even students who appear proficient while in earlier grades benefit from continued development of advanced foundational literacy skills.
When foundational skill instruction ends too early, comprehension growth often stalls.
Our findings challenge long-standing assumptions about how literacy develops. As text continues to grow in complexity beyond third grade, so:
• Foundational literacy standards must extend through eighth grade. • Adequate assessments must be used to identify where and when students are struggling. • Instructional tools must support sustained foundational skill development alongside comprehension.
Slide
To date, the initiative has contributed to policy conversations, informed new assessments, and supported the development of classroom-facing tools designed specifically for grades 4–8.
Rather than dividing literacy into two phases—“learning to read” and “reading to learn”—the research supports a continuous and coherent K–8 model of Tier I literacy instruction.
The implications continue to shape how researchers, policymakers, and educators approach literacy in the upper grades.

From recommended state standards and policy actions to assessment tools and classroom-based interventions, these resources translate Reading Reimagined’s research into practical next steps.
Reading Reimagined concludes as a research initiative—not because the work is finished, but because a foundation has been built.
The knowledge developed through this effort now supports organizations and initiatives advancing middle-grade literacy in practice, policy, and assessment, including:
Slide
Read STOP Write integrates foundational skill development with comprehension through structured lesson sequences using complex informational texts. Designed for grades 4–9, it offers a classroom-ready model for strengthening decoding and meaning-making together.
Magpie builds directly on Reading Reimagined’s research to translate insights about advanced foundational literacy skills into adaptive, classroom-ready tools designed to support sustained literacy growth beyond third grade.
BIG WORDS helps upper elementary students (grades 3-5) develop the skills needed to read and write complex, multisyllabic words. The program pairs targeted classroom instruction with teacher professional development to improve decoding, spelling, writing, and reading fluency.
Developed in partnership with Stanford University, ROAR is an adaptive digital assessment that measures grade-appropriate foundational literacy skills in grades K–12, helping educators identify where students need continued support.
