The Checklist for Individual Student Systems (CISS) is designed for school teams to self-assess the implementation status of secondary (targeted) and tertiary (intensive) behavior support systems within their school. The CISS is based on factors drawn from the Individual Student Systems Evaluation Tool (I-SSET), and the CISS is designed to answer three basic questions:1) Are the foundational (organizational) elements in place for implementing secondary and tertiary behavior support practices? 2) Is a targeted behavior support system in place? 3) Is a function-based, intensive, individual behavior support system in place?
