If you’re familiar with teaching methods for children with autism, you’ve probably heard of Discrete Trial Training (DTT). It’s a powerful, structured approach that breaks down complex skills into bite-sized, manageable steps.
I’ve seen firsthand how DTT can transform a child’s learning process. One of my past clients struggled with basic communication skills and often felt frustrated in social settings.
After implementing DTT in home-based ABA therapy, where we broke down every task into simple steps and celebrated every little success, I watched him start using words more confidently and interacting with peers. It was incredible to see his progress—and it’s a testament to the power of structured learning with DTT.
In this blog, we’ll dive into how DTT works, what makes it so effective, and some examples of how it can help kids pick up new skills. Whether you’re a parent, caregiver, or therapist, you’ll walk away with some practical ideas for using DTT in your own teaching.
What is Discrete Trial Training (DTT)?
Discrete Trial Training is a teaching method that takes big tasks and breaks them into smaller, easier-to-learn steps. It’s a part of ABA and is particularly useful for children with autism.
DTT focuses on one skill at a time, offering clear instructions and reinforcement when the child gets it right. This keeps kids engaged and motivated, making learning more fun and effective.
How DTT Works
In DTT, each trial focuses on one skill. First, you provide a prompt (discriminative stimulus) that tells the child what to do. The child responds, and if it’s correct, they get positive reinforcement—something like praise, a small reward, or a fun activity. If the response is incorrect, the teacher provides gentle corrective feedback to guide them back on track.
Because DTT is so structured, it helps kids stay focused and see their progress. Over time, they learn more and more complex skills as they get used to this step-by-step approach.
The Principles Behind DTT
DTT is built on a few important principles that help kids succeed: structure, consistency, and reinforcement.
Structure
Each DTT session follows a clear, predictable cycle. First, the child gets a prompt or cue. Then, they respond, and they either receive positive reinforcement for a correct answer or some feedback if they get it wrong.
This structure helps kids know exactly what to expect and makes the learning process smoother and more effective.
Consistency
Every session is the same—this helps create a comfortable, familiar environment where kids can focus on the task at hand. With enough repetition, kids start to remember and internalize each skill.
The consistency of DTT makes it particularly useful for children who need that extra structure to succeed.
Positive Reinforcement
Praise and rewards are key to making DTT work. Every time a child does something correctly, they receive positive reinforcement, whether that’s a high-five, verbal praise, or a sticker. This helps keep the child motivated and encourages them to keep learning and improving.
How DTT is Different from Other ABA Methods
While DTT is a part of ABA, it’s a bit different from other techniques. For example, in pivotal response training, the focus is on keeping kids motivated to learn, while DTT breaks everything down into simple, clear steps. This makes DTT great for teaching specific skills, like identifying colors or learning social cues.
In contrast, the Early Start Denver Model focuses on working on multiple skills at once, with a broader developmental goal in mind. DTT, however, is all about mastering one skill before moving on to the next.
This step-by-step approach works well for younger learners or kids who need more structure in their teaching.
The Core Components of a Discrete Trial
Every DTT session has a structure that includes five key parts: the discriminative stimulus, the child’s response, reinforcement, correction (if needed), and breaks between trials. These components help keep the session focused and effective.
The Discriminative Stimulus (SD)
The discriminative stimulus (SD) is the prompt that lets the child know what’s expected. For example, if you show a picture of a dog and ask the child to point to it, that’s the SD. This clear cue helps the child understand what action is needed, making it easier for them to respond correctly.
The Response
The response is what the child does when given the SD. It could be something like pointing to the correct picture or saying the right word. This is where the child practices the skill they’re learning.
Reinforcement
If the response is correct, the child gets positive reinforcement. This could be anything from verbal praise (“Great job!”) to a small reward (like a sticker). Reinforcement helps strengthen the behavior, making it more likely to happen again in the future.
Correction and Breaks
If the child doesn’t respond correctly, the teacher gives corrective feedback. This can be done in a gentle, supportive way to help the child understand the right answer. After a trial, a short break may be given to keep the child engaged and prevent burnout.
Setting Up for Effective DTT Sessions
Creating the right environment for DTT is crucial. A quiet, distraction-free space helps the child stay focused during the session. Ensure that the materials and reinforcers are ready to go before starting the session to minimize distractions.
Structuring the Learning Environment
The learning space should be calm and organized. Make sure there are few distractions and that the child faces the teacher to keep them engaged. Use materials that are easy for the child to see and reach, and repeat steps as needed to build familiarity.
Selecting Reinforcers
Reinforcers are essential to keep the child motivated. These can be verbal praise, toys, or preferred activities. The key is consistency—rewarding the child every time they respond correctly helps them see the connection between behavior and positive outcomes.
Step-by-Step DTT Implementation Process
Starting with DTT involves several key steps: assessing the child’s needs, setting clear goals, breaking down tasks into smaller components, and collecting data.
Planning and Implementing
First, assess where the child is in their learning. Set specific, measurable goals, then break those goals into smaller steps. Each trial should focus on one of those small steps, with clear instructions and positive reinforcement for correct responses. Tracking progress through data collection helps adjust teaching methods as needed.
Practical DTT Examples for Skill Development
DTT can be used to teach a variety of skills. For example, color identification is a great place to start.
If you show a red car and ask the child to point to it, and they do so correctly, you reinforce that behavior with praise. Over time, the child will learn to identify a variety of objects or colors using the same structure.
Teaching Receptive Language
DTT is also helpful for teaching receptive language skills. For instance, you might show a picture of a red ball and ask the child to touch it. This helps them learn to understand language by connecting it with actions. Each correct response is reinforced, building the child’s language comprehension over time.
Building Social Skills
Social skills like taking turns or sharing can be taught using DTT too. You could model how to take turns with a toy and then encourage the child to try. Positive reinforcement after each correct response encourages the child to keep practicing, helping them improve their social interactions in real-life situations.
Conclusion
Discrete Trial Training is a fantastic way to help children with autism learn new skills by breaking them down into manageable steps. By using clear prompts, structured sessions, and positive reinforcement.
DTT can teach everything from language to social skills to daily life tasks. The key is consistency, patience, and a focus on the individual child’s needs. With the right strategies, you’ll see progress and can help the child thrive in various settings.

Frequently Asked Questions
What is an example of a DTT trial in practice?
An example of a DTT trial could be when you show a flashcard with a picture of a dog on it and ask the child to say “dog.” If they get it right, they’re rewarded with something positive like praise or a small toy.
How do you choose the right reinforcers for DTT?
Choosing the right reinforcer depends on what the child enjoys. It could be a favorite toy, verbal praise, or an activity they like. The goal is to make the reinforcement motivating enough to encourage learning.
What mistakes should be avoided during DTT?
Some common mistakes include not being consistent with rewards, not adjusting teaching methods to fit the child’s needs, and not tracking progress carefully. Clear and concise instructions are also key to success.
How can DTT be adapted for older children or adults?
For older children or adults, DTT can be used with more complex tasks and real-life applications. For instance, teaching functional skills like cooking or independent living tasks can be done using the same structured method.
How is progress measured in DTT programs?
Progress is measured by tracking the child’s responses during each trial. If the child consistently responds correctly, it indicates they’re mastering the skill. If not, the teaching method or goals can be adjusted.
