Science of Reading instruction asks a lot of K-3 teachers: systematic phonics, daily phonemic awareness, fluency practice, vocabulary and comprehension. This guide maps the tools, AI and otherwise, to each of those five pillars so you know what to use for what.
Key takeaways
- The Science of Reading rests on the Simple View of Reading: comprehension = decoding × language comprehension.
- More than 40 states now require SOR-aligned instruction, mostly in K-3.
- Phonemic awareness and phonics are best served by systematic programs (Heggerty, 95 Percent Group, Reading Horizons, Lexia).
- AI earns its keep on fluency passages, vocabulary lists and comprehension questions, not on strict decodable text.
- Check every generated text against your scope and sequence before students read it.
What is the Science of Reading?
The Science of Reading (SOR) is a body of converging research from cognitive science, linguistics and education that explains how the brain learns to read and which teaching methods work best. Its foundation is the Simple View of Reading (Gough & Tunmer, 1986): reading comprehension = decoding × language comprehension. Both parts must be taught explicitly and systematically.
The movement drew on the 2000 National Reading Panel report, which identified five essential components of reading instruction. Today more than 40 states have laws or policies requiring SOR-aligned instruction, most focused on K-3, where foundational skills are built.
For teachers, SOR means moving away from balanced literacy habits (leveled readers as the main text, three-cueing) toward structured literacy: explicit phonics, systematic phonemic awareness, fluency practice with feedback, vocabulary instruction and comprehension strategy teaching. The challenge is finding materials for all five without building everything from scratch.
Science of Reading vs. whole language: what changed
If you trained before the current SOR movement, or your school is still transitioning, it helps to know what changed and why. The “reading wars” between phonics-based and meaning-based approaches go back decades. The Science of Reading is best understood as the research-based answer to that debate, not another round of it.
Whole language instruction, most influential in the 1990s, emphasized meaning and context over explicit phonics. Students were taught to guess unfamiliar words from pictures, sentence context or the first letter, a system called three-cueing. Leveled readers matched texts to a student’s approximate reading level rather than building decoding skills step by step.
The SOR critique is specific: three-cueing trains students in strategies that skilled readers don’t actually use. Reading research shows that skilled readers process letter-sound correspondences quickly and automatically rather than guessing from context. Explicit, systematic phonics builds that automatic decoding, which frees up attention for comprehension.
That doesn’t make comprehension less important. It’s the goal. But comprehension can’t rest on unreliable decoding. The sequence matters: phonemic awareness enables phonics, phonics enables fluent decoding, and fluent decoding enables comprehension. Short SOR-aligned warm-ups can activate phonemic awareness and vocabulary at the start of a lesson; our bell ringer ideas include word work and vocabulary activities.
Which states require the Science of Reading?
More than 40 states have enacted laws or adopted policies requiring SOR-aligned literacy instruction. Below are ten representative states and what their laws ask of schools. This is a summary: laws are amended often, so check your state education department for the current rules.
| State and law | What it requires |
|---|---|
| Arkansas Right to Read Act (2017) | Requires reading instruction aligned to the science of reading and requires elementary teachers to show proficiency in it. One of the earliest comprehensive state laws. |
| Mississippi Literacy-Based Promotion Act (2013) | Third-grade reading gate, literacy coaches and explicit, systematic reading instruction. Fourth-grade NAEP reading scores rose markedly in the years that followed. State resource |
| Tennessee Tennessee Literacy Success Act (2021) | Phonics-based foundational skills instruction in K-3, universal reading screeners and required teacher training. State resource |
| Ohio State budget bill HB 33 (2023) | Curriculum aligned to the science of reading from the 2024-25 school year, a ban on three-cueing, and the Third Grade Reading Guarantee. State resource |
| Louisiana 2021 early literacy law | Requires K-3 teachers to complete foundational literacy training (the state funded LETRS for elementary teachers) and screens young readers. |
| Texas HB 3 (2019) | K-3 teachers and principals complete the Texas Reading Academies; districts use high-quality instructional materials for reading. State resource |
| Florida State statute and B.E.S.T. ELA standards (2020) | Evidence-based foundational reading instruction and early screening to find students at risk for reading difficulties. State resource |
| Colorado READ Act (2012, strengthened 2019) | Reading assessment for all K-3 students, individual READ plans for students at risk, and evidence-based training for K-3 teachers. State resource |
| North Carolina Excellent Public Schools Act (2021) | Science of reading-aligned instruction and LETRS training for K-5 teachers. State resource |
| Georgia Georgia Early Literacy Act, HB 538 (2023) | High-quality, SOR-aligned curricula, universal screeners in K-3, and literacy training for teachers. |
The common thread is systematic, explicit instruction in phonemic awareness and phonics. For a regularly updated state-by-state tracker, see ExcelinEd’s early literacy policy resource. If you teach in a mandated state, leave structured literacy activities for substitutes too; our guide to writing sub plans covers what to include.
AI and curriculum tools by the 5 pillars of reading
Good SOR implementation uses different tools for different pillars. Here’s how they map.
1. Phonemic (phonological) awareness
Hearing and manipulating the sounds in spoken language: rhyming, syllables, and blending, segmenting and swapping individual phonemes. It comes before and alongside phonics.
- Heggerty: structured daily phonemic awareness routines for K-2
- 95 Percent Group: phonological awareness screener and targeted intervention resources
- Lexia Core5 Reading: adaptive phonological awareness practice with progress data
2. Phonics and word recognition
Systematic, explicit teaching of how letters (graphemes) map to sounds (phonemes), including decoding multisyllabic words, high-frequency words and morphology.
- 95 Percent Group: decodable texts organized by its phonics scope and sequence
- Reading Horizons: a systematic phonics curriculum with digital practice
- Amplify CKLA: a knowledge-building literacy curriculum with decodable readers
- Project Read AI, LitLab.ai: AI generators built to produce decodable stories for specific patterns
3. Fluency
Reading connected text accurately, at an appropriate rate and with expression. Fluent readers decode automatically, which frees their attention for meaning.
- EasyClass: generates fresh passages at a grade or reading level on any topic for repeated reading practice
- Newsela: news and nonfiction articles at adjustable reading levels
- IXL: reading skill practice with passages
Ask the EasyClass chat for “a 150-word passage about butterflies for a 2nd grade fluency check, with a word count at the end of each line.” You get new practice text every week on whatever your class is studying.
4. Vocabulary
Knowing word meanings is closely tied to reading comprehension. SOR emphasizes both academic (Tier 2) and domain-specific (Tier 3) vocabulary.
- EasyClass: vocabulary lists with student-friendly definitions, context sentences and activity ideas
- Amplify CKLA: vocabulary built into knowledge-building read-alouds
- IXL: vocabulary and context-clue practice
Ask for “six Tier 2 words from this week’s read-aloud with kid-friendly definitions and one example sentence each.”
5. Reading comprehension
The goal of reading: building meaning from text. It depends on decoding plus language comprehension, and explicit strategy instruction helps.
- EasyClass: text-dependent questions for any passage at literal, inferential and evaluative levels
- Newsela: articles with built-in comprehension checks
- IXL: comprehension skill practice with diagnostic data
8 SOR tools compared
No single tool covers all five pillars well. Most schools pair a core phonics program with supplemental materials. Pricing and free plans change, so treat the cost column as a starting point (as of October 2026).
| Tool | Best for | Pillars it supports | Cost |
|---|---|---|---|
| EasyClass | Fresh passages, vocabulary lists and comprehension questions in seconds | Fluency, vocabulary, comprehension | Free plan with monthly limits |
| Lexia Core5 Reading | Adaptive K-5 practice with data | All five | Usually district-licensed |
| 95 Percent Group | Screeners, intervention, decodables | Phonemic awareness, phonics | Some free resources; mostly district-priced |
| Reading Horizons | Systematic phonics curriculum | Phonics, fluency | Paid; often district-funded |
| Heggerty | Daily phonemic awareness routine | Phonemic awareness | Free samples; curriculum purchased |
| Amplify CKLA | Knowledge-building core curriculum | Phonics, vocabulary, comprehension | Paid; district-adopted |
| Newsela | Leveled nonfiction and news | Fluency, vocabulary, comprehension | Limited free tier |
| IXL | Skill practice across grades | Phonics, vocabulary, comprehension | Limited free use; subscription |
Where AI helps in an SOR classroom, and where it doesn’t
AI is a prep tool, not a reading program. Used well, it takes the most time-consuming material-making off your plate:
- Helps: fluency passages on your current topic, comprehension questions at several levels, vocabulary lists, sentence-level practice, parent letters explaining what you’re teaching
- Helps, if you check it: word sorts and phonics practice for a pattern you’ve taught; read every word before it reaches students
- Doesn’t replace: a systematic phonics scope and sequence, a screener, or your observation of each reader
- Be careful with: “decodable” text from general AI, which often slips in patterns your students haven’t learned yet

Frequently asked questions
What is the Science of Reading?
The Science of Reading (SOR) is decades of research from cognitive science, linguistics and education on how the brain learns to read and which teaching methods work best. It emphasizes explicit, systematic phonics, phonemic awareness, fluency, vocabulary and comprehension, and is often summarized by the Simple View of Reading (Gough & Tunmer, 1986): reading comprehension = decoding × language comprehension. More than 40 U.S. states have passed laws or policies requiring SOR-aligned instruction.
What are the 5 pillars of Science of Reading instruction?
The five components named by the National Reading Panel (2000) are: (1) phonemic awareness, hearing and working with the individual sounds in words; (2) phonics, connecting sounds to letters and spelling patterns; (3) fluency, reading accurately, at a good rate and with expression; (4) vocabulary, knowing what words mean in context; and (5) comprehension, understanding and thinking about what you read. All five need explicit instruction.
Is the Science of Reading just phonics?
No. Phonics is essential, but SOR covers all five pillars. What SOR does challenge is three-cueing (guessing words from pictures, context and the first letter), which research suggests gets in the way of building decoding skill. SOR-aligned teaching builds phonics systematically and explicitly while also developing comprehension, vocabulary and fluency alongside it. In practice this is called structured literacy.
What is the difference between structured literacy and the Science of Reading?
The Science of Reading is the research. Structured literacy is the teaching approach drawn from it: explicit (taught directly, not discovered), systematic (simple to complex in a logical order), sequential (each skill builds on the last) and often multisensory. Not every program or product labeled "SOR-aligned" is fully structured literacy, so look at the scope and sequence, not the label.
Which states require the Science of Reading approach?
More than 40 states had passed laws or adopted policies requiring SOR-aligned literacy instruction by early 2025, according to ExcelinEd. Examples include Arkansas, Mississippi, Tennessee, Ohio, Louisiana, Texas, Florida, Colorado, North Carolina and Georgia. Most focus on K-3 and require high-quality instructional materials, teacher training in foundational skills, and screeners to find students at risk. Check your state education department for current requirements.
How can AI help with Science of Reading instruction?
AI is most useful for the material-heavy parts of a literacy block: reading passages at a target level for fluency practice, comprehension questions aimed at specific skills, vocabulary lists with student-friendly definitions and example sentences, and lesson plans built around your scope and sequence. It saves prep time. It does not replace a systematic phonics program or your judgment about what each reader needs.
Can AI generate decodable texts for structured literacy?
Specialized tools can; general AI cannot do it reliably. General-purpose AI is not limited to the phonics patterns your students have been taught, so its texts often include words they cannot decode yet. Tools built around a phonics scope and sequence (for example Project Read AI or LitLab.ai, which can align to programs like Wilson, Barton or 95 Percent Group) are designed to stay within taught patterns. Whatever you use, check each text against your scope and sequence before students read it.
What tools help with decodable text?
95 Percent Group and Reading Horizons provide decodable texts organized by their phonics sequences, and AI tools such as Project Read AI and LitLab.ai generate decodable stories for specific patterns. EasyClass is better suited to fluency, vocabulary and comprehension material than to strict decodables, so pair it with a phonics-specific source.
Does EasyClass align to the Science of Reading?
EasyClass supports parts of SOR instruction rather than all of it. In the EasyClass chat you can create reading passages at a grade level or reading level for fluency practice, comprehension questions at literal, inferential and evaluative levels, vocabulary lists with definitions and context sentences, and lesson plans. It is not a phonics program and does not guarantee decodable text, so use it alongside your core phonics curriculum.
How do I transition my classroom to Science of Reading practices?
A practical path: (1) audit your phonics instruction: is it a systematic, explicit program or incidental phonics? (2) Drop or reduce three-cueing prompts ('Does that make sense? Does that look right?'). (3) Add daily phonemic awareness warm-ups in K-2. (4) Use decodable texts for beginning readers alongside grade-level read-alouds. (5) Teach Tier 2 vocabulary explicitly, including in content areas. AI tools can help you make the vocabulary activities, passages and word work for your current unit.
Are there free Science of Reading resources for teachers?
Yes. Reading Rockets (readingrockets.org) has free videos, lesson ideas and parent guides. The National Reading Panel report is free from NICHD (nichd.nih.gov/research/supported/nrp). Project Read AI's decodable story generator has a free tier. EasyClass has a free plan you can use for reading passages, comprehension questions and vocabulary lists.
