Can an OT diagnose autism?

If you're concerned your child may have autism, start with your GP or paediatrician. They can refer your child to a psychologist or psychiatrist who specialises in autism assessment. In Australia, a formal autism diagnosis typically involves:

**Who diagnoses autism:** - Paediatricians (often the first point of contact) - Clinical psychologists - Psychiatrists

**The assessment process:** Diagnosis involves detailed developmental history, observation, and standardised assessment tools. The process usually takes several sessions over weeks or months, depending on the professional's availability and your child's needs.

**What occupational therapists do:** Once your child has an autism diagnosis, an OT can assess how autism affects their occupational performance—how they manage self-care (dressing, eating, toileting), play, learning, and social participation. OTs may identify sensory sensitivities, motor coordination challenges, or difficulties with transitions and routines. They then develop strategies and interventions to support independence and participation in everyday activities.

**Accessing services:** If your child is diagnosed with autism, they may be eligible for NDIS support. OT services through the NDIS are funded based on individual goals and needs. Private OT services are also available; Medicare rebates may apply if referred by your GP (typically $60–$80 per session after the rebate).

**Next steps:** Contact your GP or paediatrician to discuss your concerns and request a referral for formal autism assessment. They can advise on whether to see a psychologist or psychiatrist and discuss timeframes in your area. Once diagnosed, your child can access OT and other supports tailored to their needs.
