The 7 Dimensions of ABA: An Introduction
What makes ABA more than a box of behavior tools?
Seven time-tested qualities—known as the Seven Dimensions—set it apart as a science, not just a strategy.
Whether you’re prepping for the exam or supervising others, these dimensions aren’t optional. They define what ABA is—and what it isn’t.
Why Dimensions Matter
Think of the Seven Dimensions as quality control for behavior analysis. They help answer questions like:
- Is the intervention socially meaningful?
- Is the behavior change actually caused by the plan?
- Can someone else replicate it?
When we skip these, the line between ABA and generic behavior management starts to blur.
The Seven Dimensions keep us grounded in data, ethics, and effectiveness.
What Are the Seven Dimensions?
In 1968, Baer, Wolf, and Risley outlined seven qualities that still define what makes ABA unique. Here’s how they show up in your work—and on the exam:
- Applied: Targets behaviors that are socially meaningful to the individual by focusing on real-world improvements: communication, safety, independence—not just convenient or easy-to-measure behaviors. If it doesn’t make a difference in the learner’s life, it doesn’t meet the standard.
- Behavioral: Focuses on observable and measurable actions. That keeps our interventions anchored in data, not interpretation. If you can’t define a behavior well enough to measure it, it doesn’t meet the standard.
- Analytic: Demonstrates a clear connection between the intervention and behavior change. Through visual analysis and data review, we show that our plan is what made the difference. If you can’t link change to your procedures, the analysis isn’t complete.
- Technological: Procedures are described clearly and completely. Someone else should be able to implement your plan based on the written description alone. Vague language (“use reinforcement when appropriate”) is a red flag. Good technology means good fidelity—and better outcomes.
- Conceptually Systematic: Every strategy ties back to the science of behavior through established principles. If a procedure uses reinforcement, prompting, or extinction, the language should say so—and the rationale should connect to known principles of behavior.
- Effective: Produces meaningful and measurable behavior change. This dimension reminds us that real-world success matters. Are behaviors improving? Are goals being met? If not, we revise.
- Generality: Behavior change lasts over time, across settings, and with different people. ABA plans must go beyond isolated environments to build lasting, flexible skills that support the learner’s life.
Each dimension strengthens the others. Together, they form the blueprint for effective, ethical ABA.
Clinical Example: Is It Really Technological?
You’re supervising a BCBA candidate who just drafted an intervention plan.
It says:
“Use reinforcement after correct responses.”
You pause. It sounds fine—until you realize it’s missing:
- What kind of reinforcement?
- How soon after the response?
- Under what conditions?
If you have to rewrite that section before anyone can implement it correctly, it’s not technological. A plan is technological when it’s written so clearly that any competent person can carry it out.
Anything less puts client progress—and data integrity—at risk.
How to Practice This
Start small:
- Review your own BIPs or sample plans.
- Ask: Can someone implement this exactly as written?
- If not, rewrite until it’s clear.
Then go further:
Try identifying examples of each dimension in your current cases.
Many interventions hit two or three—great ones hit all seven.
The Takeaway
The Seven Dimensions aren’t just historical theory.
They’re a living blueprint for ethical, effective ABA.
By the end of this series, you’ll not only be able to name them—you’ll recognize them in exam questions, clinical decisions, and daily practice.

Coming Up Next: Applied
We’ll begin with the dimension that defines why we intervene at all. Applied means ABA targets socially meaningful behavior—not just theoretical constructs.
