By knowing the symptoms or pointers, we can recognize the possibility of having dyslexia at a young age. This allows us to concentrate on the strengths of the child, not their weaknesses, and look for a learning style that suits their abilities. There is a list of several symptoms for dyslexia, but not every dyslexic has them all, in fact, most have only a few of them, and not everyone has the same ones or in the same degree. Therefore, each dyslexic is different. I did not find a standard method to diagnose dyslexia.
Methods range form very complex to rather simple approaches.
When tests are too complex or one is treated like some kind of a zombie, it will not contribute to their self-esteem, on the contrary. Inform yourself about how the test will be conducted, what will happen and why. Then explain it to the child and what the purposes of those tests are so it understands what s going on.
