Staff of TWI provide a range of direct assessment and treatment services for children, young people and families. Two key focus areas are:
1. work with children and young people (and sometimes adults) with problems around aggression and sexuality
2. assessment and treatment of people with developmental disabilities and behaviour problems.
In addition, the Institute has always maintained a strong interest in the provision of services for children and young people in out-of-home care and in supporting their carers.
