Understanding Discrete Trial Training

Table of Contents

Imagine the joyous moment when Sarah, a child with autism, successfully ties her shoelaces for the first time. This triumph isn’t just a knot; it’s a result of the magic woven by ABA therapy, in particular, Discrete Trial Training (DTT). In those small, focused steps – holding the lace, forming the loops – lies the essence of DTT. 

Join us on a journey through the transformative power of DTT, where progress is made one step at a time. 

What is Discrete Trial Training (DTT) in ABA?

Discrete Trial Training (DTT) is a structured way of teaching that breaks learning into small steps. It uses clear instructions, positive feedback, and repetition, making it effective for individuals, especially those with autism. DTT is part of Applied Behavior Analysis (ABA) and is flexible for personalized teaching. It helps with skills like communication and social interactions.

What is DTT Used For?

Discrete Trial Training is a versatile tool used to teach a wide range of skills, from basic behaviors to more advanced cognitive abilities. It is employed to address various areas, including:

  • communication
  • social interactions
  • self-care
  • academic skills
  • adaptive behaviors

DTT is particularly effective in building foundational skills that serve as building blocks for more complex abilities.

Who is Discrete Trial Training For?

DTT is tailored for children with autism spectrum disorder, ranging from early childhood to adolescence. It is designed to meet the unique learning styles and needs of individuals on the spectrum, providing a supportive framework for skill acquisition and development.


DTT is used to teach a child with autism a new skill, such as brushing their teeth. DTT would involve breaking down this task into smaller steps – holding the toothbrush, applying toothpaste, brushing each tooth – and systematically teaching and reinforcing each step until the child masters the entire sequence. This method’s success lies in its ability to adapt to the individual needs and learning pace of each child.

Components of Discrete Trial Training

The success of DTT lies in its structured approach, which comprises several key components:

  1. Antecedent: This is the initial stimulus or instruction presented to the child.
  2. Behavior: The specific response or action expected from the child.
  3. Consequence: The outcome or feedback given based on the child’s response.
  4. Prompting: Additional cues or assistance provided to help the child respond correctly.
  5. Reinforcement: Positive feedback or rewards given to strengthen desired behaviors.

What is The Difference Between ABA and DTT?

Applied Behavior Analysis (ABA) is a broader therapeutic approach that encompasses various techniques, with DTT being one of them. ABA focuses on understanding and modifying behavior, while DTT is a specific method within the ABA framework. Think of ABA as the umbrella, under which DTT serves as a targeted strategy for skill development.

Targeted Learning

DTT allows for focused teaching on specific skills, making it highly effective for children with autism.Each session is crafted to break down complex skills into small, easy components


The method can be tailored to suit the unique needs and abilities of each child.

Measurable Progress

The structured nature of DTT enables clear tracking of a child’s progress over time. Consistent assessments ensure every little achievement is a step toward overall progress.


Skills learned through DTT can often be generalized to various settings, promoting real-world application.

Limits of Discrete Trial Training

While DTT offers significant benefits, it’s essential to acknowledge its limitations:

  • May Lack Naturalistic Context: DTT focuses on structured tasks, and some critics argue that it may not always translate seamlessly to real-world situations.
  • Resource-Intensive: Implementing DTT may require dedicated time and resources, making it challenging for some families.
