Understanding Discrete Trial Training and Natural Environment Teaching

Discrete Trial Training (DTT) and Natural Environment Teaching (NET) are two well-established instructional methods used in Applied Behavior Analysis (ABA). Both are evidence-based and effective, but they differ in structure, setting, and how skills are taught and practiced.
What Is Discrete Trial Training (DTT)?
Highly Structured Learning
DTT breaks skills into small, measurable steps and teaches them in a controlled setting. Each trial follows a clear sequence: instruction, child response, and consequence (such as reinforcement or correction).
Repetition and Data Collection
Research shows DTT is effective for teaching foundational skills like language, imitation, and early learning behaviors. The structured format allows for repeated practice and precise data tracking to measure progress.
Therapist-Led Instruction
In DTT, the therapist selects the skill, materials, and pace. This approach is especially useful when a child is first learning a new or complex skill.
What Is Natural Environment Teaching (NET)?
Learning in Real-Life Settings
NET focuses on teaching skills within natural routines, such as play, meals, or daily activities. Skills are practiced where they naturally occur, which supports generalization.
Child-Led and Motivating
Research shows NET uses the child’s interests and motivation to encourage learning. Teaching opportunities happen organically, often initiated by the child’s actions or requests.
Functional Skill Development
NET is commonly used to strengthen communication, social interaction, and daily living skills that are directly applicable to everyday life.
Key Differences Between DTT and NETStructure vs. Flexibility
DTT is structured and therapist-directed, while NET is flexible and context-driven.
Skill Acquisition vs. Generalization
DTT is effective for initial skill acquisition, while NET supports applying those skills across environments and people.
How ABA Therapy Uses BothEvidence-based ABA programs often combine DTT and NET. Research shows that using both methods together supports skill mastery and real-world use.
Conclusion
Discrete Trial Training and Natural Environment Teaching are both evidence-based ABA strategies with distinct purposes. DTT supports structured skill acquisition, while NET promotes learning in real-life settings. Using both approaches together helps build skills that are accurate, functional, and meaningful.

FAQs
Is DTT better than NET?
No. Research supports both methods, and effectiveness depends on the child’s learning needs.
Can both be used together?
Yes. Many ABA programs integrate DTT and NET for balanced learning.
Which method helps with generalization?
NET is strongly associated with generalizing skills across settings.
