Eligibility Requirements

Children under age three who live in Connecticut are eligible for Birth to Three System supports because they either:

  • show a significant developmental delay of -2 SD  in one or -1.5 SD in two or more areas, or
  • have a diagnosed medical condition that has a high probability of resulting in a developmental delay

A professional evaluation team meets with the parents and child in their home and use one or more standardized tests to evaluate the child’s strengths and needs.

All areas of development are evaluated regardless of the reason for referral,  including:

  • cognitive skills – problem solving, memory, learning
  • communication skills – understanding and expressing ideas, following directions, pointing, talking
  • social or emotional behaviors – relationships and expressing emotions
  • physical development –  seeing, hearing, movements and health
  • adaptive skills –  self-help or daily living skills

All children aged 16 months and older are also screened for an autism spectrum disorder.

Families of eligible children are offered comprehensive supports to meet their goals for their child and family and connect with their community.
