What is ABA (Applied Behavior Analysis)?

Applied Behavior Analysis, or ABA, applies well-established principles of learning - such as positive reinforcement - to help people build meaningful skills like communication, social interaction, and daily living, and to reduce behaviors that get in the way of learning or safety.

ABA is individualized: a Board Certified Behavior Analyst (BCBA) assesses each client, designs a treatment plan around their goals, and adjusts it over time. Registered Behavior Technicians (RBTs) deliver much of the day-to-day therapy under that supervision.

Because it is a data-driven practice, ABA depends on consistent measurement. Clinicians collect data during every session and use it to judge whether a plan is working and what to change next.

Services are delivered wherever the skills are actually needed - clinics, homes, schools, and out in the community - and the intensity varies with the client's needs. A focused program might target a small set of goals such as communication or safety, while a comprehensive program works across communication, social, play, and daily-living domains at the same time.

The field has changed considerably over time. Contemporary practice emphasizes client assent and dignity, teaching that builds on the learner's own motivation and interests, and goals chosen together with caregivers rather than for them. Practitioners work under the BACB's ethics code, which sets expectations around client welfare, scope of competence, and informed consent.

Progress is judged against individualized, measurable goals rather than a fixed curriculum. Sessions generate the data, the supervising BCBA reviews it, and the plan changes when the data says it should. That feedback loop is what distinguishes ABA from approaches that rely on clinical impression alone, and it is why the quality of a practice's data collection has so much bearing on the quality of its care.
