Formation stage	Coalitions progress through a series of developmental stages. Please read the below statements and select the statement that best describes the work of your coalition over the past 6 months.	We are working to establish partnerships and recruit coalition members that bring together key sectors of our community (e.g., educators, law enforcement, youth) to address youth substance use in our community. Our coalition leadership is working to develop processes and procedures (e.g., communication strategies, decision-making protocols, creating workgroups/committees) to guide our CPWI initiative.
Maintenance stage	Same as above	We have conducted planning and assessment activities and have the capacity to implement prevention programs and practices that address our short-term (e.g., increase community awareness) and long-term goals (e.g., reduce and prevent youth substance use).
Institutionalization stage	Same as above	Our CPWI coalition is well-known in our community and actively involved in community-wide efforts to prevent youth substance use. We work collaboratively with community partners to share resources and offer prevention programs. Local leadership in our community consults with our coalition on matters related to youth substance use.
