The Infant Toddler Checklist (ITC) is a designed to be completed by a parent of 6 to 24 month old children, or children of age who exhibit communication delays, including Autism Spectrum Disorder (ASD).

It is designed to identify different aspects of development in infants and toddlers. Many behaviors that develop before children talk may indicate whether or not a child will have difficulty learning to talk. This Checklist should be completed by a caregiver when the child is between 6 and 24 months of age to determine whether a referral for an evaluation is needed. The caregiver may be either a parent or another person who nurtures the child daily. Please check all the choices that best describe your child’s behavior. If you are not sure, please choose the closest response based on your experience. Children at your child’s age are not necessarily expected to use all the behaviors listed.

Emotion and Eye Gaze

  1. Do you know when your child is happy and when your child is upset?
  2. When your child plays with toys, does he/she look at you to see if you are watching?
  3. Does your child smile or laugh while looking at you?
  4. When you look at and point to a toy across the room, does your child look at it?


  1. Does your child let you know that he/she needs help or wants an object out of reach?
  2. When you are not paying attention to your child, does he/she try to get your attention?
  3. Does your child do things just to get you to laugh?
  4. Does your child try to get you to notice interesting objects—just to get you to look at the objects, not to get you to do anything with them?


  1. Does your child pick up objects and give them to you?
  2. Does your child show objects to you without giving you the object?
  3. Does your child wave to greet people?
  4. Does your child point to objects?
