Be supportive
If you believe your child may have dyslexia, talk to your doctor about testing, resources, and support. There is no single test that can determine if your child has dyslexia. Your doctor may use a combination of questionnaires, medical history, psychological evaluations, and academic testing to determine if your child has dyslexia. Early intervention and a good partnership between parents and teachers are key to helping kids feel confident and successful in school and in future careers.
