Coaching is essential for sustainability of PBIS implementation.  Coaches guide teams in applying the systems and practices of PBIS.  This includes accurately using fidelity data to improve  implementation by strengthening Tier 1 foundations while scaling up to more advanced tiers.  The Illinois PBIS Network continues to direct technical assistance support to district and regional coaches with the goal of ensuring fidelity, sustainability, and the capacity to scale-up.  This enables schools to gain the confidence and competence to achieve effective outcomes for all students, including those with social/emotional challenges.
