The Child Outcomes Summary (COS) Online Learning Module provides practitioners with general information on why and how to implement the COS process. However, states and local programs have established specific policies and procedures for implementing the child outcomes measurement process. These policies and procedures cover such topics as when to collect entry and exit data, which assessment instruments can be used, and how to handle children who move in state. It is important that these policies and procedures be documented and available in writing and communicated to practitioners through professional development activities. TA providers should use this checklist to ensure that practitioners understand the policies and procedures that their state/program has set. These policies and procedures will help inform program monitoring, accountability, and improvement.
