At DD's initial paediatrician appointment (for ASD pathway), the paediatrician basically asked many questions about our concerns, developmental history (from my pregnancy, birth, milestones), about fine and gross motor skills, and various ASD-related questions to do with emotions, communication and routine.
Also did physical checks - weight, height, general examination.
She asked DD a few questions; I think mainly to see how she responded to her.
The appointment was basically to see whether she thought ASD assessment was needed and/or any other referrals should be made.
The conclusion of ours was that she recommended DD be assessed for ASD and also that a referral for ADHD assessment should be made by the school.
She gave me ASD questionnaires to fill in and also for the school to fill in.
Those completed questionnaires went with her report to a panel (held monthly) that discusses cases to decide whether they should be put on the waiting list for assessment.
DD was placed (and still is) on the waiting list (which the paediatrician said was 2-3 years in our area). Since then however, I asked our GP for a Right to Choose referral to a private provider and she has had her ASD assessment and been diagnosed.
