Key Points:
- Discrete trial training (DTT) is a structured, evidence-based method used in ABA therapy.
- It breaks down tasks into smaller, manageable steps to teach children with autism new skills.
- DTT’s benefits include improving communication, social skills, and adaptive behavior.
For children with autism, learning new skills can be difficult, especially in complex or unstructured environments. In fact, studies indicate that up to 70% of autistic individuals may also experience some form of learning disability, making it challenging for them to learn new skills. One of the most effective ways to teach these skills is through discrete trial training in ABA (Applied Behavior Analysis).
This technique involves breaking down skills into small, manageable steps and using positive reinforcement to encourage desired behaviors. Over time, children with autism can learn complex skills by mastering these smaller steps. In this article, we’ll explore the examples and benefits of DTT and how it can be used to support children with autism.
What is Discrete Trial Training (DTT) in ABA?
Discrete trial training in ABA is an evidence-based approach that focuses on teaching specific skills by breaking them down into individual components. Each “trial” in DTT consists of a clear and structured learning opportunity where a teacher or therapist prompts the child, the child responds, and the therapist provides immediate feedback, usually in the form of reinforcement.
The technique was first developed by Ivar Lovaas in the 1970s and is widely used today to teach a variety of skills, such as communication, social skills, self-help, and academic abilities. DTT relies on repetition, consistency, and clear reinforcement, which are critical to helping children with autism succeed.
What are the Key Components of Discrete Trial Training (DTT) in ABA Therapy?
Discrete Trial Training (DTT) is a foundational teaching method in ABA therapy, designed to build skills through structured, repeated learning opportunities. By breaking tasks into simple, teachable steps and reinforcing correct responses, DTT helps children with autism develop essential academic, communication, and life skills. These are its core components:
1. Clear Instruction or Prompt
The therapist begins with a specific, concise instruction such as “say hello” or “touch red.” Prompts are tailored to the child’s skill level and minimize confusion, allowing the learner to focus on the exact behavior being taught in that moment.
2. Child Response
The child responds to the instruction—either correctly, incorrectly, or not at all. This response gives the therapist insight into the child’s understanding and readiness to move forward, repeat the task, or receive additional prompting and support as needed.
3. Immediate Consequence
Following the response, the therapist immediately delivers a consequence. Correct answers earn praise, tokens, or preferred items; incorrect responses may be gently corrected. This quick feedback reinforces learning and keeps the child engaged through positive reinforcement or guidance.
4. Brief Pause Before Next Trial
A short pause separates one trial from the next, helping the child recognize a clear beginning and end. This structure builds attention, reduces overwhelm, and prepares the learner for repeated opportunities to practice the skill until mastery is achieved.
How Does Discrete Trial Training Work?
Discrete Trial Training (DTT) is a step-by-step instructional method used in ABA therapy to teach targeted behaviors and skills. It involves structured teaching moments where the child is guided to respond correctly and reinforced immediately.
Here’s how DTT is typically implemented:
How is Discrete Trial Training Beneficial for Autism?
Discrete Trial Training (DTT) is beneficial for children with autism because it breaks down complex skills into small, manageable steps taught through clear, structured trials. This approach uses repetition, immediate reinforcement, and consistent prompts to help children learn new behaviors and concepts effectively.
DTT is especially useful for teaching foundational skills like communication, imitation, and following instructions. Over time, these learned behaviors can be generalized to more natural settings. Its structured format provides clarity and predictability, which can be especially helpful for children who thrive on routine and consistency.

4 Examples of Discrete Trial Training in ABA
Discrete Trial Training (DTT) is used to teach a wide range of skills by breaking them into easy-to-digest steps. Each trial gives the child a chance to practice and receive reinforcement. Here are some common examples of how DTT is applied in real-life ABA sessions:
1. Teaching Eye Contact
The therapist says, “Look at me,” and waits for the child to make eye contact. If the child responds correctly, they receive praise or a reward. Over time, prompts are faded until the child consistently makes eye contact when asked.
2. Identifying Colors
The therapist presents two colored cards and says, “Touch red.” If the child touches the red card, reinforcement is given. This task may be repeated with different color combinations to build recognition and ensure consistent, correct responses.
3. Requesting Items (Manding)
During snack time, the therapist holds a preferred item and prompts, “Say juice.” If the child says or signs “juice,” they receive it immediately. This helps build functional communication and reduce frustration-based behaviors.
4. Following One-Step Instructions
The therapist gives simple directions like “clap your hands” or “stand up.” If the child complies, reinforcement follows. This helps children learn to follow instructions and builds the foundation for more complex task chains later in therapy.
How to Implement Discrete Trial Training at Home
Parents can incorporate discrete trial training in ABA into their daily routines to support their child’s learning. With structure and consistency, DTT can be a powerful tool for teaching everyday skills in a familiar environment. Here are some simple steps for implementing DTT at home:
1. Set Clear Goals
Begin by identifying specific skills that the child needs to work on. These could include communication, social interactions, self-help skills, or academic abilities. Make sure the goals are achievable and broken down into smaller steps.
2. Create a Structured Environment
Designate a quiet area free from distractions for DTT sessions. Consistency in the environment will help the child focus and learn more effectively.
3. Use Positive Reinforcement
Always provide immediate reinforcement after the child responds correctly. This could be praise, a favorite toy, or a treat. Positive reinforcement motivates the child to continue engaging in the desired behavior.
4. Be Consistent
Consistency is key when using DTT. Make sure to use the same instructions, prompts, and reinforcement for each trial. Repetition and consistency will help the child internalize the skills being taught.
