Discrete Trial Training (DTT) is the most popular teaching method used in Applied Behavior Analysis (ABA). DTT is a successful teaching method because DTT removes all the add-ons and boils down the teaching to exactly what the learner needs to be successful. DTT may feel very robotic and repetitive, but when done correctly, this approach will bring out amazing gains in language, imitation, attending, self-help, motor, and play skills.
Components of DTT
Teaching Trial: With DTT each presentation of a discriminative stimulus (SD) is a “teaching trial”. EACH teaching trial includes: presentation of materials, deliver SD, prompt incorrect response OR reinforce correct response, and clear materials. This process is repeated over and over during a teaching session in a fast-paced manner. Data should be collected after the completion of each trial.
Breaking Down Tasks: DTT is designed to break down complex skills into small, separate tasks to teach and shape a skill over time. For example, if you were teaching a student to write their name, this could take 5-10 steps to learn. First, the student may learn to trace each letter in their name individually, then the student may learn to write each letter in their name individually, then the student may be directed to “write their name” with verbal prompts, then the teacher would fade the prompt over time, start with providing all letters of their name, then fade one letter at the time until the student can write their whole name independently. An example of fading is below:
“Write your name” M-E-G-A-N (spoken by teacher)
“Write your name” M-E-G-A (spoken by teacher)
“Write your name” M-E-G (spoken by teacher)
“Write your name” M-E (spoken by teacher)
“Write your name” M (spoken by teacher)
“Write your name” (no prompt)
SD → Response: The SD is the instruction or demand presented to the student. Some examples of SD’s include: “touch nose” “stand up” or “what number”. The goal of an SD in DTT is that the SD leads to a specific desired response. If the student responds correctly, provide reinforcement. If the student responds incorrectly, prompt the student. It is important to vary the presentation of the SD so the student will generalize. Meaning, you do not always want to say “touch nose”, by doing this, if another staff worked with the student and said “find nose” the student may not respond correctly due to varying word presentation.
Here is an example of a DTT session.

Picture books are an excellent way to develop early literacy skills. They promote vocabulary and appreciation of narrative. When children read with adults, they learn to associate reading with enjoyment and happy memories.
