  • Children younger than age 3 may be eligible to receive these services on the basis of criteria established by the Virginia Department of Behavioral Health and Developmental Services.

  • EI consultation typically focuses on early communication, social, and play skills.



  • ABA-based instruction can also promote mastery and enjoyment of academic material.

  • Students in general education, as well as students with disabilities, may benefit from individualized instruction that is both fun and challenging.
