The Catch – 22: Even though AVKO has demonstrated that 75% of all words poor readers cannot read contain advanced phonic patterns that are not systemically taught in school, schools cannot and will not systemically teach them. Why? Because they don’t have either a listing of these patterns or a listing of the words that contain these patterns.
Where can schools get a listing? Only from AVKO. The listing of the patterns and the listing of all the words by patterns is to be found only in AVKO’s The Patterns of English Spelling.
