Our son was tested in grade 4 to help us understand why he had trouble with finishing work. The testers used the following:

WRAML2 (Wide Range of Assessment of Memory and Learning),
Developmental Test of Visual-Motor Integration,
PPVT-III Peabody Picture Vocabulary Test, EVT Expressive Vocabuary Test, CTOPP Comprehensive Test of Phonological Processing, Wechsler Individual Achievement Test

Stealth dyslexia is not widely known because two doctors from the US west coast coined the term, Drs Fernette and Brock Eide. They wrote The Mislabeled Child and a new book called the Dyslexic Advantage. I have the Mislabeled Child and still want to buy the new book. I think that poor scores in Rapid Naming are a diagnostic for dyslexia. My son has excellent reading comprehension but poor rapid naming and poor visual working memory. In Canada, Dyslexia is not a term used in the creation of an IEP, but I found that people mostly understand what I am talking about when I use the term.
