"...also called a behavioral contract, is a document that specifies a contingent relationship between the completion of a specified behavior and access to, or delivery of, a specified reward such as free time, a letter grade or access to a preferred activity" (Cooper, Heron & Heward, 2007, p. 551).

"An independent group contingency is an arrangement in which a contingency is presented to all members of a group, but reinforcement is delivered only to those group members who meet the criterion outlined in the contingency" (Cooper et al., 2007, p. 568).

"An interdependent group contingency is one in which all members of a group must meet the criterion of the contingency (individually and as a group) before any member earns the reward" (Cooper et al., 2007, p. 569).

"Under a dependent group contingency the reward for the whole group is dependent on the performance of an individual student or small group" (Cooper et al., 2007, p. 568).

Self-monitoring and supervision feedback have been found to increase staff performance (Richman, Riordan, Reiss, Pyles, and Bailey, 1988)

Arco (2008) noted three procedures that were effective at increasing and maintaining the performance in behavioral treatment programs, (i) defining the process before training, (ii) providing on-the job supervisory feedback, and (iii) having staff provide self-generated outcome feedback before and after training.
