The Comprehensive Application of Behavior Analysis to Schooling (CABAS®) applied behavioral analysis (ABA) system may be helpful for children with autism.

The CABAS early intervention program is a school-wide system for using ABA methods. It applies ABA methods to help the whole child. This case study describes one girl who started intensive ABA therapy in a CABAS system at the age of 2 years 10 months of age. Her communication and socialization skills were at the level of a 1 year-old. The intensive therapy methods were evidence-based, using recent methods that were reported to be potentially helpful. Researchers tested her progress over a 3-year period. When she started, she had a low IQ and had trouble learning. After 3 years of intensive ABA therapy in a CABAS® system, her cognitive and communication skills were average for her age group. She was still behind for her age in social skills. She was able to move into a mainstream classroom.
