The Indiana General Assembly passed legislation that permits schools to include children with Developmental Delay (DD) in its non-duplicated count of pupils in programs for mild and moderate disabilities, effective July 1, 2018. The State Board of Education is directed to amend the definition of developmental delay, effective July 1, 2018, to provide that developmental delay is a disability category solely for students who are at least 3 years of age and less than 9 years of age. This document provide guidance on these changes.
