School Resource Unit

Arapahoe County Sheriff’s Office School Resource Officers (SROs) are committed to keeping our students safe and secure in their learning environment. SROs work in the schools using a triad concept established by the National Association of School Resource Officers (NASRO), working as law enforcement officers, guest speaking in classrooms, and serving as informal counselors. Each SRO has specific training related to working as law enforcement officers in our schools through NASRO, as well as through the Colorado Association of School Resource Officers (CASRO). 

The SROs handle criminal complaints, conduct follow up investigations and enforce traffic laws on school facilities, as well. They also attend numerous school functions such as parent/teacher organization meetings and sporting activities. SROs provide classroom instruction and participate in community-related work groups for youth issues, such as keeping kids engaged in school and other productive activities.

The School Resource Officer Unit works closely with the Littleton Public School District, Cherry Creek School District, as well as schools in Byers and the Town of Deer Trail.
