In response to concerns about what to call something when it's not as big as an organization: If you are applying TI principles to policies and practices relevant to students and educators, I would still consider using the term trauma-informed. Ideally the whole system becomes TI. But a classroom is a system. A department is a system. A program is a system. A curriculum is a system. A private practice is a system. The Missouri Model may also provide some helpful guidance for what to call things as an organization/system progresses through the stages of becoming trauma-informed.
