What Is Backward Chaining in ABA Therapy?
Backward chaining is a teaching procedure used in Applied Behavior Analysis (ABA) therapy where a multi-step skill is taught starting with the last step in the sequence. The behavior technician or behavior analyst completes all the earlier steps for the learner, and the learner is responsible only for the final step. Once that step is mastered, the learner takes on the second-to-last step, and so on, working backward through the chain until they can perform the entire sequence independently.
The strategy is built on top of a task analysis, which is the process of breaking a complex skill into smaller, teachable steps. Once the task analysis is complete, the team chooses a chaining method to teach the steps. Backward chaining is one of three main options, alongside forward chaining (starting with the first step) and total task teaching (working on every step every session).
Backward chaining is widely used in ABA programs for children with autism, especially for daily living skills, self-care routines, and any task with a clear sequence and a built-in reinforcer at the end. According to the Indiana Resource Center for Autism at Indiana University, one of the strengths of backward chaining is that the learner immediately understands the benefit of completing the task because they experience the natural reinforcer at the end of every successful trial.
In practice, the behavior technician carries the learner through the earlier steps using physical, verbal, or visual prompts and then steps back at the final step to let the learner complete it on their own. As the learner masters each step, the prompts move one step earlier in the chain. Over time, the learner takes on more and more of the skill until they’re performing the whole routine without help.

Examples of Backward Chaining in ABA Therapy
Example 1: Teaching a child to put on a shirt
A behavior technician is teaching a five-year-old client to put on a shirt independently. The task analysis breaks the skill into several steps: pick up the shirt, orient it correctly, pull it over the head, push one arm through, push the other arm through, and pull the shirt down at the waist. Using backward chaining, the behavior technician handles every step except the last, leaving the learner to pull the shirt down at the waist on their own. The natural reinforcer—the satisfaction of being dressed plus the behavior technician’s praise—follows immediately. Once that step is mastered, the behavior technician adds the second-to-last step, then the next, until the learner is dressing independently.
Example 2: Backward chaining for handwashing
For a seven-year-old learner working on independent handwashing, the behavior analyst writes a task analysis with steps including turning on water, wetting hands, applying soap, scrubbing, rinsing, turning off water, and drying with a towel. The behavior technician guides the learner through every step up to drying, then steps back and lets the learner pick up the towel and dry their hands. Drying becomes the first step the learner owns. The team systematically works backward across sessions until the learner washes their hands independently from start to finish.

Example 3: Toilet training using backward chaining
Toilet training routines are often taught using backward chaining because the final step—washing hands and returning to play—contains a strong natural reinforcer. The therapist supports the learner through pulling pants down, sitting on the toilet, voiding, wiping, and flushing, then steps back for the handwashing and return-to-play step. As that step becomes independent, the behavior technician adds the previous step, and so on. Toileting is one of the most common skill areas where backward chaining is applied, because the structure of the routine maps so cleanly onto the method.

Why Is Backward Chaining Important in ABA Therapy?
Backward chaining is valuable because it builds in success and reinforcement from the very first trial. By the time the learner takes their first action, the rest of the sequence is already complete, which means the natural reinforcer—a clean face, a finished snack, a buttoned coat—follows immediately after their effort. That tight pairing between behavior and reward is part of what makes backward chaining so motivating for many learners.
The approach also reduces the cognitive and motor load on the learner during early teaching. Instead of fighting to complete an entire complex routine, the learner focuses on one manageable step at a time. As skill builds, more of the chain becomes theirs. This gradual handover supports children who can become overwhelmed by long, multi-step demands or who have struggled with forward chaining approaches that delay reinforcement until many steps are mastered.
For behavior technicians and behavior analysts, backward chaining is also a flexible tool. It can be applied to dressing, grooming, mealtime routines, vocational tasks, household chores, leisure activities, and academic sequences. The method pairs naturally with prompting strategies; for more on how prompts support skill acquisition, see our glossary entry on prompts in ABA therapy.
FAQs About Backward Chaining
What is the difference between backward chaining and forward chaining?
Forward chaining teaches the first step of a sequence first, then adds the second, and so on, working from the beginning of the routine toward the end. Backward chaining reverses that order, teaching the last step first and working backward. The learner reaches the natural reinforcer immediately under backward chaining, which can be especially motivating early in skill acquisition. Forward chaining can feel more logical for skills where the sequence builds naturally from start to finish. The behavior analyst chooses the method based on the learner’s skills, motivation, and the nature of the task.
When is backward chaining the best choice for teaching a skill?
Backward chaining tends to work especially well when the final step of a routine produces a strong natural reinforcer—eating a meal, going outside, finishing dressing, returning to a preferred activity. It’s also a strong choice for learners who have struggled to stay engaged with long sequences or who get discouraged when reinforcement is delayed. For skills where the early steps are simpler than the later ones, forward chaining or total task teaching may be a better fit.
How is backward chaining different from a backward chaining with leaps ahead procedure?
A standard backward chaining procedure requires the learner to master each step before moving to the previous one in the chain. Backward chaining with leaps ahead is a modified version where the behavior technician occasionally has the learner attempt earlier steps that haven’t been formally taught yet, to check whether the learner can already perform them. If they can, the team can skip ahead instead of teaching each step in strict sequence, which speeds up acquisition for some learners.
Can backward chaining be combined with other ABA strategies?
Yes. Backward chaining is almost always paired with prompting strategies, like most-to-least prompting, to support the learner through the steps they haven’t mastered yet. It also pairs with reinforcement procedures, visual supports such as picture sequences or video models, and data collection systems that track progress on each step. The team layers strategies based on what the individual learner needs at each point in the program.
Can parents use backward chaining at home?
Yes, and many families do, often with coaching from a behavior technician or behavior analyst. Backward chaining is well-suited to home routines like getting dressed, brushing teeth, packing a backpack, or making a simple snack. Parents can ask the team for a written task analysis and a guide to how each step should be prompted and faded, so the strategy stays consistent between session and home. Consistency across settings is one of the biggest factors in how quickly a skill generalizes.
Key Takeaways About Backward Chaining
- Backward chaining teaches a multi-step skill starting with the last step and working backward as each step is mastered.
- It relies on a task analysis that breaks the full skill into clearly defined, teachable steps.
- The strength of backward chaining is that the natural reinforcer follows the learner’s effort immediately on every trial.
- It pairs naturally with prompting strategies, reinforcement procedures, and visual supports.
- Behavior technicians use backward chaining for dressing, hygiene, toileting, mealtime routines, vocational tasks, and many other skill areas.
- Backward chaining is one of three main chaining methods, alongside forward chaining and total task teaching, and the behavior analyst selects the best fit for each learner and skill.
