This document provides a list of recommended existing resources for state Part C and Part B 619 staff and technical assistance (TA) providers to utilize to support evaluation planning for program improvement efforts (including the State Systemic Improvement Plan, SSIP). There are many resources available related to evaluation and evaluation planning, but these were selected as the ones more relevant to and useful for early intervention and preschool special education. Additional resources can be found at the GRADS360 Phase II Evaluation Resource Library. As program improvement and the SSIP work is ongoing and evolving, this list will be updated as new and relevant resources become available.
