There is indeed a long term individualized strategy for each child. That strategy keeps being adjusted throughout the evolution of the child, according to the progress made in each domain of development. It continues on at adult age. These schemes give a lot of information to the teachers and to the parents with regard to what is the appropriate level that can be successfully taught in each domain of development at the present time for the child. Teaching a specific behavior ceases to be the main goal of the teachers endeavor.
