Much of the success when developing and implementing Tier 2 practices hinges on the foundation that has already been laid. A majority of system level change required to facilitate identification of students who require additional support and effective delivery of research-based interventions have already been developed if schools are effectively implementing a schoolwide approach for Tier 1. 

Before moving forward with development and implementation of Tier 2 practices, schools should consider the extent to which the schoolwide system and Tier 1 practices are in place. Meeting the criteria shown in this Tier 2 Readines Checklist is generally a broad indicator of readiness.
