Evidence & Results
The Every Student Succeeds Act (ESSA) is the federal standard for evaluating whether education programs work. EBLI has earned Tier 3 status — meaning independent, correlational studies with statistical controls have shown positive student outcomes. This qualifies EBLI for Title I, II, and IV funding and meets the evidence bar for most district procurement processes. These three implementations are the studies behind that designation.

The Science Behind EBLI
Linguistic Phonics is a research-aligned approach to literacy instruction developed from the work of cognitive psychologist Diane McGuinness. It starts with what every child already knows — spoken language — and teaches them how print maps to the sounds they already use. This is the foundation of EBLI.
Most phonics programs start with letters, teaching them in isolation, starting with the letter name and sound— a print-to-speech orientation. This is oriented around the letters and the rules to manage them. This requiries memorizing hundreds of letter-sound correspondences, phonics rules and their exceptions, syllable types, and declarative knowledge (vocabulary such as dipthongs, fricatives, and schwa).
Linguistic Phonics reverses the direction. It starts with the child’s spoken language, starting with words they know., isolating the sounds, then matching the spellings to the sound This speech-first instruction simplifies and accelerates reading and spelling acquisition by highlighting patterns in the alphabetic code, which aligns with how the brain learns best, and incorporating the alphabetic principle by attaching the man-made symbols (letters) to the the sounds that represent them in words (speech).
The result: Reading, spelling, and writing acquisition are simplified and accelerated, avoiding cognitive overload for students. Instruction is integrated from the start and applied immediately to reading and writing — not taught as separate skills bolted together and applied later.
Traditional Phonics, Print-to-Speech Approach
Letters, which are man-made, lead instruction
Linguistic Phonics, Speech-to-Print Approach
Sounds, which are natural, lead instruction
FOUNDATIONAL RESEARCHER
Cognitive Psychologist · University of South Florida (Emeritus)
Coined the term “Linguistic Phonics” and developed the foundational analysis of the English alphabetic code that EBLI’s methodology is built on. Her work demonstrated that starting from speech — not print — aligns instruction with how the brain actually processes language.
PEER-REVIEWED JOURNAL ARTICLE
SLP · Literacy Researcher & Interventionist
Published the peer-reviewed case for Linguistic Phonics in The Educational Therapist, examining how LP accelerates student learning, reduces teacher workload, and improves outcomes — with direct reference to EBLI’s approach.
PROGRAM DEVELOPER
Founder, EBLI · Literacy Educator & Researcher
Developed Evidence-Based Literacy Instruction (EBLI) directly from McGuinness’s Linguistic Phonics principles. Over 20+ years, she built a complete instructional system — phonics, vocabulary, fluency, comprehension, handwriting, and writing — with proven outcomes across thousands of students.
PRACTITIONER RESEARCHER
1st Grade Teacher · Kilby Laboratory School, University of North Alabama
National Board Certified Teacher and 2025–26 Goyen Literacy Fellow with 20+ years of experience. In her first year implementing EBLI, 100% of her first graders reached grade-level benchmark — up from 37% at the start of the year — achieving a median of 184% of typical growth. Her peer-reviewed case study, published in the IALS Journal, documents these outcomes alongside gains in spelling, fluency, and student confidence.
Supporting Research
Beyond EBLI’s own outcomes, a growing body of peer-reviewed research demonstrates that intensive, speech-first phonological instruction produces measurable changes in brain activation, white matter development, and reading outcomes — particularly for students with dyslexia.
Simos, Fletcher, et al · 2002 · Peer-reviewed
Brain imaging study. Magnetic source imaging of 8 children (ages 7–17) with dyslexia showed that brain activation patterns normalized after 80 hours of intensive remedial instruction — demonstrating that the brain can be retrained through targeted phonological intervention. 8 typical readers served as controls.
Huber, Donnelly, Rokem & Yeatman · 2018 · Peer-reviewed
White matter MRI study. Diffusion MRI data collected at regular intervals during an 8-week intensive reading intervention revealed large-scale changes across white matter tracts, occurring in concert with measurable growth in reading skill.
Targeted Reading Intervention · 2017 · Randomized Controlled Trial
385 students across 15 schools (220 intervention, 165 comparison). Kindergarten and first-grade teachers identified struggling readers who were randomly assigned to groups. Effect sizes of .36 to .63 on standardized reading tests.
Denton, Fletcher, et al · 2006 · Peer-reviewed
Tertiary intervention study. 27 students with severe reading difficulties received a 16-week intensive intervention using the Phono-Graphix decoding program — including 14 who had not responded adequately to 1–2 prior tiers of reading instruction. Published in the Journal of Learning Disabilities.

In this panel presentation, program creators and literacy teachers share the research behind and principles of Linguistic Phonics and focus on how this approach bridges research with instructional implementation.
PEER-REVIEWED RESEARCH · WEBINAR
Jennifer Newman and Svetlana Cvetkovic interviewed by Nora Chahbazi
A conversation with the authors of the peer-reviewed paper making the case for Linguistic Phonics instruction in the United States — exploring why the evidence points to a speech-to-print approach and what it means for how we teach reading.

Core instruction: Daily use within literacy block for 30-60 minutes
Intervention: 30-60 minutes/session, 1-5 days/week
Best results: Be consistent with teaching EBLI processes and methodology while implementing print-to-speech practices.
Orientation: 4-6 hours asynchronous (theory, platform, assessment, materials)
Total training: 40-60 hours, integrated teacher training and student instruction
Model: Learn EBLI while teaching your class, group, or individual student(s); video support fades as confidence builds
Included: EBLI Teacher Training & Student Lessons (ETSL) platform with videos, training modules, student instruction, printable materials
Ready-to-go: Activities, materials, text to read, and lessons planning are all provided.
Access: 1-year ETSL access included with training
