EBLI (Evidence-Based Literacy Instruction): What It Is and How It Works

If you have been researching dyslexia, structured literacy, or better ways to teach reading, you have probably come across EBLI. EBLI, also known as Evidence-Based Literacy Instruction, is a structured literacy approach designed to teach the skills children need to read, spell, and understand written language.

The problem is that most explanations of EBLI quickly disappear into terminology: phonemic awareness, phonics, decoding, encoding, orthographic mapping, Wilson, Orton-Gillingham, the science of reading, and more. This article cuts through the noise and explains what parents actually need to understand: what EBLI is, how it teaches reading, how it differs from other structured literacy approaches, and what the research actually says about it.

Key takeaways

What is EBLI?

EBLI is Evidence-Based Literacy Instruction, a structured literacy program created by former nurse Nora Chahbazi in 1997, that teaches reading, spelling, and writing by starting with the sounds in spoken words and then teaching the letters that spell them. The approach is called speech-to-print. Wilson, Barton, and Orton-Gillingham belong to the same research family, and all of them teach the connection between sounds and letters directly and systematically. EBLI works that connection from the opposite end.

The science of reading is a different thing. That term covers the entire body of research on how people learn to read, why reading can be difficult, and which types of instruction are most effective. EBLI is one program built on parts of that research. Online the two get used interchangeably. They are not the same.

Why are schools turning to EBLI to teach reading?

Reading instruction in American schools is going through its biggest overhaul in decades, and EBLI is one of the methods in the conversation.

For years, reading researchers had warned that many schools were teaching reading the wrong way, using methods that had children guess words from pictures and context instead of decoding the letters and sounds. That approach, known as three-cueing, has since been restricted or banned in more than 15 states as districts shift toward evidence-based instruction.

California followed in October 2025 with AB 1454, which funds teacher training in evidence-based reading instruction and requires evidence-aligned instructional materials in elementary classrooms. A federal version, the Science of Reading Act, cleared a House committee unanimously in March 2026 and now sits on the House calendar. It is not law yet.

Districts that dropped three-cueing need something to replace it. EBLI is one of the candidates, and its founder, Nora Chahbazi, appeared in Sold a Story.

How does EBLI teach reading?

EBLI teaches reading in the direction speech developed: sound first, then print. Lessons begin with words a child can already say, separate those words into their individual sounds, and then teach the letters English uses to represent those sounds.

Take the word map. A child can say it long before they can read it. To read it, the child has to recognize that the spoken word contains three separate sounds, /m/ /a/ /p/, and connect them to the written letters m, a, and p.

That ability to hear and work with individual sounds in spoken words is called phonemic awareness, and it is one of the strongest early predictors of later reading success. By about age five, children already use most of the roughly 44 speech sounds of English in everyday language. What they may not yet be able to do is consciously separate those sounds inside words. EBLI teaches that skill and immediately connects the sounds to print.

Chahbazi was a neonatal intensive care nurse when her daughter fell behind in reading. She taught her daughter at home with a speech-first method, reportedly in about three hours, and spent the next 25 years building EBLI around it.

How is EBLI different from traditional phonics?

The core difference is direction. Traditional phonics is print-to-speech: it starts with letters and teaches the sounds they make. EBLI is speech-to-print: it starts with the sounds a child already says and teaches the letters that spell them. That reversal also changes how each handles the messiness of English.

Take the familiar rule that a silent e makes the vowel say its name. It holds in “hope,” “tape,” and “cute,” and fails in “have,” “give,” and “done.” Louisa Moats found that many classic phonics rules hold roughly half the time. A child who was promised rules keeps score, and after enough exceptions they reach a conclusion: I must be bad at this.

The actual code is messier than the rules admit. English has around 44 sounds, 26 letters, and roughly 250 common spellings. One sound can be spelled several ways: /ee/ appears in “me,” “see,” “sea,” “key,” and “funny.” And one spelling can carry several sounds: “ea” reads differently in “eat,” “bread,” and “steak.” EBLI puts that variability on the table in the first lesson.

In place of rules, children build a habit called flexing. A child reads “bread,” tries the /ee/ sound, hears “breed,” knows that is wrong, swaps in the short /e/, and lands the word. Researchers call the underlying skill set for variability and have linked it to stronger word reading. The child never guessed. Every step ran through the letters. When I test students, that self-correction is what I listen for. It tells me more than the score does.

Does EBLI teach sight words?

Yes, though not the way many parents remember learning them.

A sight word is any word a reader recognizes instantly. It does not have to mean a word memorized from a flashcard. Linnea Ehri’s research showed that automatic recognition develops through orthographic mapping, the process where the brain ties a word’s spelling to its sounds and meaning until retrieval takes a fraction of a second.

So EBLI runs even irregular words through their sounds. Take said. Most of the word behaves predictably. The unusual part is the vowel spelling, which gets pointed out and practiced, rather than having the child memorize the whole word as a visual shape. High-frequency word practice still has a place, provided the child is paying attention to the letters and sounds inside the word rather than its outline.

Does research show that EBLI works?

The research is much stronger for the instructional practices EBLI uses than it is for EBLI as a specific branded program.

The National Reading Panel reviewed 38 studies and found that explicit, systematic phonics beats instruction without it. The evidence behind phonemic awareness training, sound-to-print connection, and spelling instruction runs deep. Those are all central parts of EBLI.

The program itself has a shorter record. A randomized study of 63 teachers in grades 2 through 5 found no significant reading gains from EBLI training, and the researchers noted implementation problems that may have affected the result. A 2025 report following 815 students showed promising growth, but EBLI itself helped produce the study, and no peer-reviewed journal has evaluated it. There is also no research showing that speech-to-print instruction outperforms other strong forms of systematic phonics.

How can you tell if reading instruction is working?

Watch for three changes at home, whatever name the program carries. The child starts attempting unfamiliar words instead of skipping them. Corrections start coming from the child, a changed sound rather than a glance up at you for rescue. And spelling starts representing the sounds the child actually hears, even when the spelling is still wrong, because a reasonable misspelling shows the underlying system is forming.
