The Science of Reading is a body of research spanning five decades that identifies how the brain learns to read, emphasizing systematic phonics instruction, phonemic awareness, and structured literacy approaches proven effective for all learners.
What is the Science of Reading?
The Science of Reading isn't a curriculum or product—it's a vast, interdisciplinary body of research conducted over fifty years across the fields of cognitive science, neuroscience, linguistics, and education. This converging evidence identifies how the brain actually processes written language and which instructional approaches work best. A foundational finding: unlike speaking, which develops naturally, reading must be explicitly taught. The Science of Reading has driven a major shift in education policy, with 38 states and the District of Columbia now passing laws to align literacy instruction with this research.
Key Takeaways
- Research-based understanding of how the brain learns to read—not a specific curriculum
- Built on the "Five Pillars": phonemic awareness, phonics, fluency, vocabulary, comprehension
- Emphasizes explicit, systematic phonics over "balanced literacy" or "whole language" approaches
- Structured Literacy is the instructional approach that applies Science of Reading research
- 38+ states have passed legislation requiring Science of Reading-aligned instruction

Why It Matters Now
The Science of Reading has gained prominence because literacy outcomes remain stubbornly poor—only about 35% of American children read proficiently according to national assessments, a rate that's barely budged for decades. Meanwhile, Mississippi dramatically improved its reading scores after rejecting balanced literacy for phonics-based instruction, providing a real-world proof point. Investigative journalism, particularly Emily Hanford's work, exposed how widely-used curricula ignored decades of research about how children learn to read. For homeschool families, this matters because many popular programs now explicitly align with Science of Reading principles—and understanding why helps you evaluate curriculum claims.

The Bottom Line
The Science of Reading represents our best understanding of how children actually learn to read, backed by decades of research across multiple scientific disciplines. For homeschool families choosing reading curriculum, look for programs that explicitly teach phonics systematically, build phonemic awareness, and don't rely on guessing from pictures or context. The good news: over 90% of children can learn to read successfully with research-based instruction. Understanding the science helps you cut through marketing claims and choose curriculum that actually works.
