If you suspect your child might have dyslexia, you can contact your child's teacher, principal, special education administrator and/or physician about screening options. Federal and Tennessee state laws require school districts to "identify, locate, and evaluate all children with disabilities from birth through age twenty-one (21), regardless of the severity of their disabilities." (Source: TN.gov) In Tennessee, all students are required "to participate in a universal screening process to identify those who may need additional support and/or other types of instruction," per the Say Dyslexia law passed in 2016.
Families in Tennessee with children 2.5 years old and younger who have disabilities or developmental delays should contact the Tennessee Early Intervention System at 800-535-9725 for more information about no-cost services.
