About#

The Infant-Toddler Checklist is a caregiver-reported screening tool assessing early communication and social development in children aged 6 to 24 months. It evaluates three domains: social communication, expressive speech, and symbolic functioning. The ITC is commonly used to identify early risk for communication delays and autism spectrum disorder.
