Although both teams work together and staff work across both teams, the criteria is very different for both. Children are referred to PDT with development delay and can often catch up with support or will go on the waiting list for ASD assessment or will be referred for additional support in the areas they are struggling with. However, school age criteria is very different and children need to have global developmental delay/ significant learning disability and or an associated health need which a lot of the children who come through the pre school team do not have.
