Duration recording documents how long a student engages in a specified behavior. This type of data collection is appropriate for behaviors that have a distinct beginning and ending.

Trial-by-trial data collection is used often for academic tasks. Record data for each opportunity, or trial, the student is given. The data may be reported in trials or in percentages, depending on how the goal is written.

Antecedent-Behavior-Consequence (A-B-C) data collection serves to identify the antecedents (A) that set the stage for or trigger problem behavior (B) to occur and the consequences (C) that appear to maintain that behavior. Typically, this data is collected over multiple sessions and is used to identify patterns and functions of behavior.
