Orton-Gillingham is the most widely recognized and effective methodology for teaching students with dyslexia or language-based learning disabilities. The methods of O-G have been continuously confirmed by ongoing research in the science of reading.
O-G is a structured literacy approach for teaching reading and spelling to those who struggle the most, such as those with dyslexia. It presents the English language system in a structured and sequential pattern, building up from the smallest units of language to the most complex (sounds to syllables, multi-syllable words, sentences, and stories). This approach is multisensory, using sight, sound, movement, and touch to reinforce learning.
Orton-Gillingham was developed by Samuel Orton and Anna Gillingham in the 1930's, pioneering a practical classroom system for neurological learning challenges. Learn more at The Orton Gillingham Academy or International Dyslexia Association.
Wilson Reading System is a full-developed program based on the principles of O-G. Like O-G, it is structured, explicit, systematic, and multisensory.
Wilson follows a similar sequence of skills to O-G and employs similar techniques, such as "tapping out" sounds on fingers while reading and spelling and "air-writing" sight words.
Wilson has its own training and materials, and covers a wider range of skills. In addition to word reading and spelling, Wilson develops fluency, vocabulary, and comprehension.
Wilson is endorsed and accredited by the International Dyslexia Association.
