It takes some time to change any behavior. Part of the plan should be effective consequence strategies. Planned consequences reinforce the acquisition and use of alternative skills and reduce the effectiveness of the problem behavior should it continue to occur. Having planned for consequences should help teach the student that his or her use of alternative skills is a better way to achieve the desired outcome. Because it takes time for a behavior intervention plan to change a student's behavior, it is important for the IEP team to decide what will happen when the problem behavior persists. If the behavior is manageable, it is important to provide responses that discourage the problem behavior and do not provide the desired function or outcome of the behavior. In some cases the behavior can be extreme. The IEP team should develop a crisis plan to address such situations. First the group needs to define what a crisis is. Then they should describe the intervention procedures to be implemented, including who will be involved. They must identify the resources needed to implement the plan and agree on procedures for documenting crisis use
