ICDC provides intensive, individualized services, following the principles of applied behavior analysis (ABA). While there are many interventions and theories about how best to treat autism, only ABA has been supported by sound scientific research. The core of ABA is an intensive educational experience, in which the functions of behaviors are examined and specific methods are chosen to address the functions of behaviors. Basic skills are taught utilizing positive reinforcement procedures, which includes providing an experience rich with affection and praise. Skills that are taught in the classroom are generalized to the natural environment, so that children can function independently and maximize their potential.

Family involvement is essential to the success of these programs. Family members are taught how to implement the specialized teaching methods, as well as how to cope with their children's challenging behaviors.
