Abstract: A behavoir training and modification device includes a board having a plurality of pegs extending from its front face. The pegs are arranged in a predetermined pattern such as a grid of rows and columns. Indicator plates can be marked with visual indicia representing individuals, task, behaviors. The indicator plates include apertures to permit so they can be slid onto the pegs. The plates are positioned on the board to assign tasks to specific individuals and to indicate behavior traits to be modified. Status indicator plates are used to acknowledge the completion of tasks, and the manifestation of desirable and undesirable behavior. Transparent plates are provided so that when multiple plates are stacked on a single peg the plates lower in the stack are visible through the upper plates in the stack.
