As the result of previous System of Care grants to the Colorado Department of Human Services, Office of Behavioral Health (OBH), Colorado has supported 18 local Communities of Excellence to implement high-fidelity wraparound with peer support, and developed the Cross-Systems Training Institute to credential the system of care workforce and improve the quality of services to children and families in the system of care. This initiative has been branded COACT Colorado, the State's Trauma-Informed System of Care. As a result of the advocacy efforts aligned with COACT Colorado, the Colorado legislature passed Senate Bill 19-195 last May, which will result in several infrastructure and financing developments for Colorado's system of care for children and youth with serious mental health challenges within the next several years. With the support of funding opportunity SM-20-007, the Office of Behavioral Health will implement the proposed project, titled "COACT Colorado: Expanding and Sustaining Colorado's Trauma-Informed System of Care." This project will expand system of care services beyond the existing 18 Communities of Excellence to include the remainder of the State, and further develop infrastructure for the Colorado Cross-Systems Training Institute and youth and family voice. Efforts will be aligned with Federal initiatives such as the Family First Prevention Services Act, as well as Colorado Senate Bill 19-195, to develop a comprehensive children's behavioral health system of care that is guided by youth and family voice and offers integrated services for children involved in multiple systems, including behavioral health, child welfare, juvenile justice, and education. This proposal outlines plans to expand system of care services and infrastructure. The six major goals of the project are as follows: 1. Implement Communities of Excellence providing high-fidelity wraparound with peer support as part of a comprehensive system of care in large regions of Colorado that have not previously received system of care funding, 2. Expand the Cross-Systems Training Institute to support the system of care workforce and clinical quality of care by providing training and technical assistance to providers serving children, youth, and families, 3. Expand and sustain infrastructure to support family and youth voice, 4. Develop an infrastructure and standards for intensive psychoeducation, coaching, and support for caregivers of children with behavioral health challenges, 5. Improve and disseminate a data infrastructure for level of care stratification to align with system of care principles, SB 19-195, and the Family First Prevention Services Act, to improve the ability for children and families to receive the appropriate level of care, and 6. Support system of care services and financing in all funding sectors of Colorado to implement the children's behavioral health system reform outlined in Colorado SB 19-195 and the Family First Prevention Services Act. A minimum of 225 families in rural and frontier regions of the State will be served with high-fidelity wraparound and peer support, and a minimum of 2,000 providers will receive training and professional development aligned with system of care values and principles.
