A state-run NDIS replacement scheme for children with autism and developmental delays will offer screenings for three and four-year-olds.
Victoria's Thriving Kids program will include two extra tests for children from October when it launches, the state government announced on Thursday.
One will be conducted before kindergarten and another before school, with clinicians and allied health professionals identifying development delays and connecting families with support.
The assessments will be stacked on top of an existing 10 key ages and stages visits from when a child is born to the age of about three and a half.
"This is both assessment and early intervention at the earliest possible opportunity ... so that kids get to prep ready to start on their education and school journey," Children Minister Lizzie Blandthorn told reporters.
