The Yarran Early Childhood Intervention Services was established in 1979 when a group of parents with disabled children formed a support group. This group applied for and received funding for a part time teacher. They established themselves in a borrowed garage.
In 1980 they were loaned premises in a portable classroom in the grounds of Kariong Pre-school in Mt. Penang Training School. Yarran operated in these premises till 27 November 2002 when they relocated to a purpose built centre at East Gosford. In 1984 Wyong Council lent them a rates collection office in a car park at The Entrance so that the Wyong area would be better serviced. Late in 1988 an offer was made to Yarran from the Department of Employment, Education and Training for funds to build a centre on Crown Land reserved for Yarran at Bateau Bay. This centre was opened in September 1990.
Yarran has grown and expanded over the last thirty-four years. All programs adopt a family centred philosophy to guide their decision-making and activities. Yarran is family driven and child centred.
