What is a non-reader?

     My definition of a non-reader is a person, young or old, who does not read because he cannot read. He lacks the skills of a fluent reader such as phonics,  vocabulary and comprehension. We label this person "illiterate" which gives the impression that something is wrong with him.  In most cases, there is nothing wrong with the person other than he has not been taught the skills he needs in order to be able to learn how to read.
