The concept behind discrete-trials is that for some individuals larger, more complex skills need to be broken into smaller more discrete steps. Each step is taught individually and then is strategically intermixed with other acquired skills. Most often DTT programs occur at a table top as they allow for materials to be placed in front of the learner. DTT is commonly assumed to be synonymous with Applied Behavior Analysis, which is an incorrect comparison.
