Orton-Gillingham (OG) is an approach to teach reading, spelling, and writing.
It delivers clear, straightforward instruction on the sound each letter of the alphabet makes and how those letters are combined to represent the sounds in printed text.
The main trouble for those with dyslexia is the sound-to-letter symbol connection. Dyslexics have a much harder time associating and memorizing the sounds of our language to printed, two-dimensional symbols such as the alphabet than non-dyslexics. Dyslexics need more straightforward, clear and detailed instruction on the relationship of spoken sounds to the written symbols than what is typically taught in school.
For non-dyslexics, we do not think much about this. But for many dyslexics, they pick up on these patterns subconsciously, and they need to know why and when to use a C, K or CK to represent the sound /k/.
Dyslexics do not lack intelligence in any way! This subconscious pattern recognition of the inconsistency with how the /k/ sound is written in English demonstrates their intelligence. They just need more direct instruction on how spoken sounds and letters represent themselves in the English language.
So, the logic of the English language can get very confusing for dyslexics, UNLESS it is taught in a very systematic, cumulative (building up in complexity), and multi-sensory way that is student-paced — meaning the student does not move forward until they have mastered the lesson and each skill is automatically done without prompting or correction.
AN EXAMPLE IS THE SOUND: /k/
The /k/ sound in English can be represented in printed-text four different ways:
C, K, CK and CH (as in the word “Christmas”)
CK usually occurs at the end of one-syllable words, right after a short vowel as in… sock, thick, luck
However, when the one-syllable word has a vowel followed by another consonant as in dark or thank the C is dropped, and the word ends in just a K, most of the time.
What is multi-sensory?
The Orton-Gillingham approach is multi-sensory. Every concept is taught using a combination of: Sight, Sound, Touch, Speaking, Listening, Writing.
Each lesson lasts 60 minutes, and each concept is taught 10 consistent ways using sight, visual memory, sound, touch (tapping out the sounds of words using fingers),
speaking the words and writing the words. By completing two hours of multi-sensory lessons a week, in a systematic way that slowly builds at the student’s pace, the brain physically builds pathways to read and associate sounds to symbols in the most effective manner. fMRI studies show that Orton-Gillingham instruction, taught as designed by a trained instructor, will change the neuro-pathways in the brains of dyslexics so they actually read like non-dyslexics.
This is why it is SO IMPORTANT that the instruction is given with fidelity — strict adherence to each of the 10 parts of the lesson and the explanations of spelling rules of the English language.
When your child finishes with an Orton-Gillingham approach, they will have learned all the spelling rules of the English language, and be able to explain why things are spelled the way they are better than most American English teachers. Spelling is the window into how the brain is associating the sounds of language with the printed form of the language. Spelling and reading are woven together and show an accurate picture of how your child is associating sounds and symbols.
If English is so irregular, how can a dyslexic master spelling?
English is considered an opaque language, meaning cloudy, blurry or hazy. Our language is a hybrid of many languages including Latin, Greek, German, French and Spanish to name a few! The language has evolved over time, and many words are no longer spelled phonetically. They are spelled from tradition rather than an exact representation of the spoken sounds in the word.
Examples of opaque language are: of, some, dome, come, does, people
English is opaque – which makes reading and spelling more difficult
The reading researcher, Stanislaw DeHaene, studied reading error rates in first graders across Europe and found the largest error rates occurred in the languages that were the most opaque, with first graders in English speaking countries having the highest reading error rates due to the complexity of how sounds are represented in printed text.

The Orton-Gillingham method will help your dyslexic child learn the English alphabetic code, but there will always be words that are more difficult to spell because the sound/symbol correlation is not exact (the word “does” is a great example). Orton-Gillingham’s method will train their brain to begin relating the sounds to the symbols, and allow them to “crack the code” of English reading, spelling and writing with a much higher degree of accuracy.
