Defining the Science of Reading

The science of reading is a vast, interdisciplinary body of scientifically-based research about reading and issues related to reading and writing.

This research has been conducted over the last five decades across the world, and it is derived from thousands of studies conducted in multiple languages. The science of reading has culminated in a preponderance of evidence to inform how proficient reading and writing develop; why some have difficulty; and how we can most effectively assess and teach and, therefore, improve student outcomes through prevention of and intervention for reading difficulties.

Evidence-Based Reading Instruction

Interdisciplinary insights into the process of reading have been uniform in their findings—both on learning to read and on teaching reading. The persuasive body of evidence that constitutes the “science of reading” documents the skills and capabilities needed to develop a “reading brain.” Neural connections must be made in the phonological assembly region of the brain to enable reading, and these connections must be built through informed instruction.

Explore Systematic Phonics Resources Aligned to Science of Reading Research

Decodable Readers

Print + Digital • Grades K-1

Decodable Readers offer authentic practice with phonics skills and sight words through fiction and nonfiction titles on high-interest topics with familiar storylines. Digital and print formats fit any instructional model or budget.

Decodable Fluency Builders

Print + Digital • Grades K-1

Support and assist fluency development with authentic decoding experiences—high-quality phonics readers and Teacher Cards that include differentiation scaffolds and lesson plans, making direct connections to the skills students are learning in their reading blocks and providing crucial practice.

Grade 2 Decodable Passages

Print + Digital • Grade 2

Build automaticity with decodable reading practice. Sixty decodable passages for phonics and foundational skills applications are delivered in a consumable format, allowing student annotations as they practice decoding—aligned to 10 knowledge-building topics to build language comprehension.

Benchmark Phonics

Print + Digital • Grades K-5

Explicit, systematic, multi-modal instruction designed for Tier 1 and Tier 2 instruction is based on the latest Science of Reading research. Unit topics are designed to build vocabulary and content knowledge, with application to reading and writing emphasized.

Benchmark Phonics Intervention

Print + Digital • Grades K-5

This comprehensive phonics program, designed for Tier 3 intervention, is ideal for students performing two or more years below grade-level expectations. Based on the latest reading research, it aligns to the tenets of Structured Literacy, with sequential and multi-modal instruction and spiraled review and repetition.

Sound-Spelling Transfer Kit

Print + Digital • Grades K-2

Develop foundational skills and vocabulary for transfer between Spanish and English with this comprehensive program combining explicit instruction with engaging learning activities. Build on native language understanding and teach application to a new language—maximizing transfer, language acquisition, and biliteracy.

Theoretical Models

Theoretical models have provided a visual for this process. The Simple View of Reading explained that reading comprehension is a product of decoding and language comprehension, while Hollis Scarborough’s Reading Rope points out how the two work together—with word recognition becoming increasingly automatic (fluent) as language comprehension becomes increasingly strategic.

In viewing these models, it is critical to recognize that decoding without deep levels of language comprehension is insufficient to develop skilled reading. And deep levels of language comprehension without decoding will not result in skilled reading either. Readers need proficiency in both, thus these essential elements must be taught and developed as children learn this life-changing skill.

Note: McKenna and Stahl (2009) have developed a Modified Cognitive Model of the Reading Rope that adds the Strategic Knowledge that readers use (e.g., general and specific purposes for reading, knowledge of reading strategies) to further understand how readers comprehend text.

Curriculum Evaluation

Just as brain imaging studies have been consistent in their depiction of the neural connections necessary for fluent reading, there is consensus on what must happen instructionally to wire the brain for the ability to read. In order to determine how well your program and resources reflect Science of Reading guidance, consult our Science of Reading Evaluation Checklist, developed by author and early reading expert Wiley Blevins.

The Necessity of Text Variety

As students are taught to develop and hone both the decoding and language comprehension required for skilled reading, an array of decodable texts, leveled texts, and trade books should be used. Children read books to practice foundational skills, to develop fluency, and for pleasure, too. Classrooms need a range of texts for different instructional purposes.

Different texts receive different degrees of emphasis at each grade level. But ALL are needed for a comprehensive literacy solution.

Phonics lessons must be explicit and systematic, with a clearly defined scope and sequence. And they must include Decodable Texts for reading application.


Trade Books develop vocabulary, knowledge, and perspective, and allow children to see themselves in the world. Teachers read books aloud in order to build vocabulary and background knowledge, and to instill a love of reading.


Knowledge-Building Leveled Texts eliminate barriers, scaffolding students and lifting them up, making them eager and able to tackle complex grade-level texts.

More Resources That Support Evidence-Based Reading Instruction

Vocabulary & Content Knowledge

Readers rely on their knowledge of the meanings of specific words (vocabulary) in a text and their background content knowledge related to the topic of that text. These skills intertwine with decoding as the student tackles and accesses this new text.

Culturally Relevant Trade Books & Read-Alouds

As students build their decoding skills, equal time must be dedicated to flooding them with vocabulary and developing their content knowledge through rich read-alouds with interactive conversations. These efforts plant the seeds of comprehension.

Systematic Phonics

In alignment with science of reading research, phonics instruction must follow a defined scope and sequence with ample review and repetition.

Each skill is explicitly introduced and applied in ways that get students thinking and talking about how words work.
