      As a service to those who visit our website, we have provided a Speech & Language Checklist for children, by which you can determine your child's abilities at various age levels. In addition, a questionnaire on the Warning Signs of Stuttering Behaviors can also be used to determine if a child should be evaluated for a fluency disorder (stuttering). You may submit the Checklist and Questionnaire to us by following the prompts and clicking on "Submit". An email response will be sent to you.
