The ability to read proficiently is absolutely fundamental to a student’s success at school and all throughout life!
In the wise words of a certain Dr Seuss,
“The more that you read, the more things you will know. The more that you learn, the more places you’ll go.”
And in a shorter, yet no less true, quote from Margaret Fuller,
“Today a Reader, Tomorrow a Leader.”
At first glance, breaking the science of reading into a list of components may seem like the most logical way to understand it. However, doing so can actually reflect a fundamental misunderstanding of what the science of reading truly is.
The science of reading is not an “instructional program, “ consisting of
“Step 1: Do this…”
“Step 2: Do that…”
Rather, it is a vast body of gold-standard research that explains how the human brain learns to read.
Because this research has identified skills and teaching practices that reliably support reading development, the science of reading is often mistaken for a checklist of instructional methods.
For example, decoding is a critical skill for literacy, and the science of reading clearly shows that it must be taught explicitly. However, decoding itself is not “the science of reading.”
To make this body of research more accessible, educators often rely on well-established instructional frameworks and models that translate research into classroom practice. Due to extensive research into the topic resulting in the creation of four main “Science of Reading Models,” we will explore just one for the purpose of this article:
The Five Pillars of Reading Instruction
What Are the Five Pillars of Reading Instruction?
The Five Pillars of Reading Instruction, sometimes referred to as the five pillars of early literacy, were identified by the National Reading Panel as essential for reading proficiency.
These pillars are:
Phonemic awareness
Phonics
Vocabulary
Fluency
Comprehension
Each pillar plays a critical role in developing strong reading skills. When educators understand and explicitly teach these elements, they significantly increase the likelihood that students will learn to read proficiently.
Research across cognitive psychology, linguistics, and neuroscience has produced a strong evidence base for instructional practices that support the development of each pillar. By understanding the science behind these areas, educators can design instruction that aligns with how the brain learns to read—helping students become confident, capable readers.
1. Phonemic Awareness
Phonemic awareness is the ability to hear, identify, and manipulate individual sounds—known as phonemes—in spoken words. It reflects an understanding that words are made up of separate sounds and includes skills such as blending, segmenting, and manipulating those sounds.
2. Phonics
Phonics refers to the relationship between letters and the sounds they represent. It involves using this knowledge to decode written words during reading and to encode words during spelling and writing.
While phonics is often mistakenly viewed as the entirety of the science of reading, it is just one essential part of a much larger system. Decades of research show that systematic phonics instruction significantly improves reading outcomes, particularly for beginning readers, at-risk students, and those with learning difficulties. When taught explicitly and sequentially, phonics provides learners with a strong foundation for accurate word reading.
3. Fluency
Fluency is the ability to read accurately, efficiently, and with appropriate expression. It involves automatic word recognition, pacing, and prosody, allowing readers to focus their cognitive energy on meaning rather than decoding.
4. Vocabulary
Vocabulary encompasses the words students must understand in order to communicate effectively through reading, writing, speaking, and listening. It includes knowledge of word meanings, relationships between words, and how words are used across different contexts.
A strong vocabulary supports both decoding and comprehension. The more words students know and understand, the easier it becomes for them to make sense of increasingly complex texts.
5. Comprehension
Reading comprehension is the ability to understand, interpret, and construct meaning from text. It draws on multiple underlying skills, including decoding, vocabulary knowledge, background knowledge, and higher-order thinking strategies.
Comprehension is often considered the ultimate goal of reading. Rather than being a single skill, it represents the integration of many components working together.
What are the Benefits of Science of Reading-Based Instruction?
The greatest strength of the science of reading–aligned instruction is its ability to support all learners through explicit, direct, and cumulative teaching methods that have been proven to develop skilled readers.
Elements such as phonics, vocabulary, and syntax are often highlighted, but they represent only individual pieces of a much broader research base. The science of reading is not static; it is a continually evolving body of evidence that deepens our understanding of how the brain learns to read and which instructional practices are most effective.
Well-known frameworks such as the Five Pillars of Early Literacy, Scarborough’s Reading Rope, the Simple View of Reading, and Structured Literacy all emerge from this research. These models translate complex findings into practical guidance for classroom instruction.
When educators use these frameworks to guide explicit instruction—spanning phonemic awareness, decoding, vocabulary, and meaning-making—they create learning environments where every student has a genuine opportunity to achieve reading success.
