What is the Orton-Gillingham approach?
The Orton-Gillingham (OG) approach is a structured, research-based method for teaching reading and spelling. It was originally developed by Dr. Samuel Orton and Anna Gillingham and is especially effective for students with dyslexia or other language-based learning difficulties. The Wilson Reading System® is a structured literacy program that uses the Orton-Gillingham approach. While Wilson is the program, OG is the method behind how the instruction is delivered. Key Principles of Orton-Gillingham Instruction Orton-Gillingham instruction is: Systematic and Sequential – Skills are taught in a specific order that builds step by step. Multisensory – Lessons include visual, auditory, and hands-on activities to reinforce learning. Explicit – Every concept is directly taught with clear explanations. Diagnostic and Prescriptive – Instruction is based on the student’s individual needs. Teachers adjust lessons based on what the student has mastered or still needs to practice. Flexible – Teachers can change direction during a lesson based on student performance to make sure every concept is solid before moving on. What Does Multisensory Structured Language (MSL) Instruction Include? Wilson Reading lessons follow a Multisensory Structured Language (MSL) approach based on Orton-Gillingham. MSL instruction includes: Phonological Awareness – working with sounds in words Phonics – connecting sounds to letters and patterns Syllables – breaking words into parts to help with decoding Morphology – learning prefixes, suffixes, and base words Orthography – understanding spelling rules and patterns Syntax – building sentences and understanding grammar Semantics – building vocabulary and comprehension

What assessments do you use to evaluate and monitor progress?
I use a variety of assessments to evaluate and monitor each student's progress.

How long does the program take?
There’s no set timeline for completing the Wilson Reading System® because every child’s learning journey is different. Progress depends on many factors, including: Frequency of sessions Attendance and consistency The student’s current reading level and background knowledge Outside factors like stress, transitions, or health The degree of language-based difficulty Independent practice outside of lessons That said, most students working two times per week typically complete the program in 3 to 4 years. Students who meet more frequently may move through more quickly. Some may need additional time depending on their individual needs. What matters most is mastery—not speed. The Wilson program is divided into 12 Steps, and each one builds on the last. Rushing through can lead to gaps that affect long-term success. My goal is to ensure students develop strong, lasting reading and spelling skills by taking the time they need to build true confidence and independence.

Is the Wilson Reading Program the right fit for my child?
Students need to be tested using the WIST assessment in order to determine the appropriate level of instruction and intervention support needed for your child. The Wilson Reading Program is a Tier 3 program. It is designed for individuals who require the most intensive level of instruction. The Wilson Reading System is appropriate for students with significant difficulty in word-level decoding, automatic word recognition and fluency, and spelling, including students with dyslexia who require an intensive remedial program. In addition to the Wilson Reading System, Wilson also provides Tier 1 and 2 programs. Tier 1: Fundations (Grades Pre-K-3) Tier 2: Fundations (Grades K-3) or Just Words (Grades 4-12 and adults.)
