Applied Behavior Analysis (ABA) is an evidence-based discipline rooted in the science of learning and behavior. ABA focuses on understanding how behavior works, how it is affected by the environment, and how learning occurs through reinforcement, prompting, shaping, and systematic teaching strategies. Practitioners use structured assessment and data-driven intervention plans to teach new skills, increase independence, and improve overall quality of life (Cooper, Heron, & Heward, 2020).

ABA is widely used to support individuals with Intellectual and Developmental Disabilities across the lifespan, not only in early intervention but also in adolescence and adulthood. For adults with IDD, ABA can:

• Build daily living and vocational skills

• Increase community participation and independence

• Support communication, social interaction, and self-advocacy

• Reduce challenging behaviors and replace them with appropriate alternatives

• Enhance adaptive functioning through individualized intervention plans

Research suggests that ABA-based interventions can improve functional skills, promote self-determination, and enhance overall well-being for adults with developmental disabilities (Kitts et al., 2021).

In higher education and training environments, ABA provides structured teaching methods that break skills into manageable steps while reinforcing progress. This evidence-based approach is particularly beneficial for students with IDD, as it supports:

• Skill acquisition through repetition and positive reinforcement

• Instruction tailored to individual learning needs

• Data-driven progress monitoring

• Increased engagement, motivation, and academic participation

ABA contributes to accessible education by promoting inclusive learning environments where students receive support aligned with their unique learning profiles (Leaf et al., 2016).
