What Is Forward Chaining in ABA Therapy?
Forward chaining is an Applied Behavior Analysis (ABA) teaching procedure used to teach multi-step skills by starting with the first step in the sequence and adding subsequent steps as the learner masters each one. Behavior analysts use forward chaining for skills made up of a series of distinct actions that need to happen in a specific order—brushing teeth, putting on a coat, washing hands, packing a backpack. The procedure is one of three main chaining methods, alongside backward chaining (which starts with the last step) and total task teaching (which teaches every step in each session).
Forward chaining begins with a task analysis: the behavior analyst breaks the skill into its component steps and writes them down in order. For a handwashing routine, the task analysis might include 11 or 12 discrete steps, from turning on the water to drying hands with a towel. The behavior technician then teaches step 1, providing prompts and reinforcement until the learner performs it independently. Once step 1 is mastered, the technician teaches step 2 while still requiring step 1; once both are independent, step 3 is added; and so on through the chain.
According to a task analysis and chaining tip sheet from the Marshall University Autism Training Center, chaining procedures are particularly useful for teaching activities of daily living, where multi-step routines like toothbrushing, dressing, and meal preparation can otherwise overwhelm a learner. Breaking the skill into smaller steps reduces frustration and allows the learner to experience success at each level before advancing.
Forward chaining tends to work well when the learner needs to understand the logical sequence of a task from start to finish, when early steps in the chain are easier than later ones, or when the natural order of the routine makes starting at the beginning the most sensible approach. The behavior analyst selects forward chaining based on what the learner already does, the structure of the skill being taught, and the practical realities of when and where the routine occurs.

Examples of Forward Chaining in ABA Therapy
Example 1: Teaching a child to wash hands
A behavior analyst designs a handwashing program for a five-year-old client and creates a 10-step task analysis: walk to sink, turn on water, wet hands, get soap, rub hands together for 20 seconds, rinse hands, turn off water, get towel, dry hands, throw away towel. The behavior technician begins with step 1, prompting the learner to walk to the sink and reinforcing successful completion with praise. The technician completes the remaining steps for the learner so the routine finishes. Once the learner walks to the sink independently for several sessions, the technician adds step 2. After several weeks, the learner is performing the full chain with minimal support. This kind of routine is one of many activities of daily living that chaining procedures are well-suited to teach.
Example 2: Building a morning getting-ready routine
A behavior technician working with an eight-year-old client uses forward chaining to teach a morning routine: get out of bed, use the bathroom, brush teeth, get dressed, eat breakfast, pack backpack. The therapist coaches the family on how to implement the chain at home. Each morning, the parent prompts only step 1 (“Time to get out of bed”) and provides verbal cues for any remaining unmastered steps. As the learner masters each step, the parent fades prompts forward through the routine. Over a few months, the learner is moving through the morning routine with much less parental involvement.
Example 3: Learning to make a sandwich
A behavior analyst designs a sandwich-making program for a teenage client preparing for greater independence. The behavior technician uses forward chaining: step 1 is getting the bread out of the bag, step 2 is opening the peanut butter jar, and so on through 12 steps to assembling, cutting, and plating the sandwich. The learner masters one or two new steps each week. The technician collects data on independence at each step and shares it with the team. When the learner can complete the full chain independently across multiple sessions, the team moves the program to maintenance and starts a new self-care goal.

Why Is Forward Chaining Important in ABA?
Forward chaining matters because many of the skills that most affect a learner’s independence—self-care, daily living, vocational tasks—are multi-step sequences. A learner who can’t put on a coat independently can’t leave the house without help. A learner who can’t make a meal can’t feed themselves. Forward chaining provides a structured way to teach these sequences one piece at a time, building toward full independence in skills that meaningfully expand the learner’s capacity to navigate their world.
The procedure also has a practical advantage: it teaches the routine in the natural order it occurs. Forward chaining matches how the skill will actually be performed, which can make the learning feel more intuitive for the learner and more transferable across settings. The first step is naturally the cue for the second step, and so on through the chain, so the learner is practicing the stimulus-response relationships that will sustain the behavior outside of teaching sessions.
Forward chaining is most effective when the team implements it consistently. Each session needs to follow the same task analysis, deliver reinforcement at the same criterion, and fade prompts in the same way. When implementation varies across behavior technicians, family members, or settings, the learner may struggle to consolidate the chain. For more on why consistency in ABA matters so much, read our blog on the importance of sticking to consistent ABA therapy.
Like most ABA teaching procedures, forward chaining is one tool the behavior analyst chooses from among several, based on what fits the learner and the skill best. The team’s decisions about which chaining method to use, when to advance through the chain, and when to fade prompts are all data-driven and individualized.

FAQs About Forward Chaining
How is forward chaining different from backward chaining?
Both procedures teach a multi-step skill one step at a time, but they differ in where they start. Forward chaining starts with the first step in the sequence and adds steps moving toward the end. Backward chaining starts with the last step (with the team completing all prior steps for the learner) and adds steps moving toward the beginning. Backward chaining has the advantage that the learner experiences the natural completion of the task on every trial, which provides built-in reinforcement. Forward chaining has the advantage that the learner practices the routine in its natural order from the start.
What is a task analysis, and why is it essential?
A task analysis is a written breakdown of a multi-step skill into its component steps, listed in order. It’s the foundation of any chaining procedure. Without a clear task analysis, the team can’t consistently teach the same steps in the same order across sessions, which would undermine the chain. Behavior analysts develop task analyses by observing competent performers, consulting subject-matter experts, or breaking down the skill themselves based on what each step requires from the learner.
How does forward chaining compare to total task teaching?
In total task teaching, the learner attempts every step in the chain during each session, with the behavior technician providing prompts wherever needed. In forward chaining, the learner is only working on the current target step (and any previously mastered steps); the remaining steps are completed for them. Total task teaching can be more efficient when the learner has some baseline ability across the chain. Forward chaining can be more effective when the learner needs explicit, step-by-step practice on each component before moving on.
How do behavior technicians know when to move to the next step?
The team sets a mastery criterion in advance—something like “independent performance for three consecutive sessions” or “90 percent accuracy across two days.” When the learner meets the criterion on the current step, the technician adds the next step to the teaching. Setting the criterion too low can cause the chain to crumble as new steps are added; setting it too high can stall progress. The behavior analyst calibrates the criterion to the learner and the skill.
Can families use forward chaining at home?
Yes, and many forward chaining programs work best when families implement them at home, since the relevant routines (handwashing, getting dressed, mealtime tasks) happen there. The behavior analyst typically writes out the task analysis, models the procedure, and coaches the family on how to deliver prompts and reinforcement consistently. The therapist may also support implementation across settings to keep the program moving forward when in-clinic sessions aren’t available.
