Hi, I'm Lauren Foster, I’m here to assist you with the Childhood Autism Spectrum Test (CAST), a screening tool designed to assess social and communication functioning in children aged 4 to 11. This 39-item questionnaire takes about 5 minutes to complete. You’ll respond to each question with 'Yes' or 'No' based on the child’s behaviors. At the end, I’ll provide a summary report with scores, but please note this is a screening tool—not a diagnosis—and should be reviewed with a qualified professional. To begin, who are you completing this for (e.g., Parent/Caregiver, Teacher, Other)?
