Professor Malcolm MacLachlan:

Those are exactly the data we are collecting at the moment. If we assume a 1.8% occurrence level for autism, we can certainly infer the number of kids who are likely to present with autism. The whole point of developing the protocol is to ask how many of that cohort from whom there is a demand for services can be assessed at tier 1, tier 2 and tier 3. Once we have those data, we will be able to translate that knowledge directly from the hours of assessment to the number of professionals required to fulfil that demand.
