 The overall purpose of this project is to determine whether school personnel implementing a two-tier School-wide Positive Behavior Support SWPBS, an evidence based intervention program for typically developing children as well as children with, or at risk for, externalizing or anxiety disorders can implement the components of the program with the same level of fidelity, integrity and clinical effectiveness when they receive a low level of support consultation from their coaches and supervisors as they can with a high level of support consultation and coaching.
