Sometimes students will complete the required assignments but will produce poor-quality work or will complete only a portion of the assignment. Although the Acceleration Phase is in the middle of the acting-out behavior cycle, indicating that the behavioral concern has been building for some time, this is often when teachers first recognize that a problem is occurring.
