We haven't done any specific training on that BUT everything we do is about working in partnership with the parents and allowing the parents to be the experts on there own child. In Victoria we use the Parents Evaluation of Development status (PEDS) tool and is a series of questions that parents answer about there child at varying ages. Rather than having to assess what children can ad can't do according to what the books say they should at set ages, and understanding that there are variations of normal and that some need to do sooner and some take longer to allow and average to be formed.
