What is OG?

Orton-Gillingham (OG) is the grandfather of multisensory structured language programs. It has been proven to be effective for more than 80 years. While other phonics and basal programs may impact decoding skills, they are not well structured to support spelling. OG recognizes that reading and spelling are interrelated and works to connect reading, spelling, writing and oral language.


Based on best teaching practices, OG provides a structured and sequential format moving from concrete to abstract and from simple to complex. There is sufficient repetition to achieve automation and considerable scaffolding techniques to support students at any level. These characteristics make the Orton-Gillingham method applicable to ALL students including those with dyslexia and English Language Learners as well as ALL subjects — science, math, social studies, etc. Read Ron Yoshimoto’s most recent article on what makes OG unique and effective by clicking here.


What is Orton-Gillingham International?
Orton-Gillingham International (OGI) is an organization whose mission is to place effective Yoshimoto Orton-Gillingham methods into the hands of teachers. OGI provides training, certification, resources and consultation to ensure successful outcomes for educators and their students. Co-director Ron Yoshimoto’s effective, time and classroom tested approach, takes the Orton-Gillingham method and applies it to a classroom, small group and/or individual instruction. Utilizing Yoshimoto’s unique tools, every teacher can become Yoshimoto OG qualified and provide essential reading instruction to each child.


The Approach
OGI-trained teachers are similar to doctors who assess symptoms, prescribe a treatment and adjust it based on a patient’s response. OGI teachers plan an approach based on data, assess areas of concern, and continuously refine the approach to achieve success.


While other phonics programs have a “one size fits all” approach, OGI is inherently customizable according to each student’s individual needs. Teachers can easily produce effective, individualized lesson plans in a variety of subjects, which can be used as follows:

  • Tier One — designed for all children

  • Tier Two — tailored to address specific needs for small groups

  • Tier Three — further customized for one-on-one application for those who need more intensive help


Furthermore OGI lessons are structured, sequential and cumulative so that instruction uses data and multisensory procedures to reinforce information. These procedures, which are varied to prevent boredom and improve reading fluency and comprehension, include:

  • Card drills

  • Decoding of words

  • Spelling, introduction of concepts

  • Dictation of sentences

  • Structured and sequential learning experiences

  • Repetition to enhance automaticity


Financially Sound
The quality and affordability of OGI teacher training and the inclusion of all materials eliminates the need for additional programs and products.
