DTT is a simplified, one-on-one, teacher-directed instructional method with goals focusing on each individual student (Smith, 2001). In
discrete trial training, instruction is provided in multiple, quickly presented learning
trials (Sigafoos et al., 2006). Smith (2001) describes DTT as having five parts: (a) cue,
(b) prompt, (c) response, (d) consequence, and (e) intertrial interval. The cue is a
discriminative stimulus, in the form of a brief, clear directive or question (e.g., touch
your head). The prompt is used to guide the student to the correct response and may be
given with the cue or immediately after. For example, the teacher may model the
correct response. These prompts are faded as the student shows mastery of the skill.
