Once you educate yourself about the signs of dyslexia I think it becomes fairly obvious whether a person has it or not.

Lisa says in her dyslexia blog post

"Dyslexia can be diagnosed by a professional, but it is often costly. I always look for indicators of dyslexia, because the only necessary component is how to treat it. Diagnosing dyslexia can often make the person feel better, because just knowing that he/she is intelligent is always helpful. So many dyslexics are traveling through life thinking that they are dumb, when in fact, they are highly intelligent."

What do you think? Do you feel it's more important to just get to work on the problem with a reasonable assessment? Do you feel capable of making your own decisions?
