Crime Stopper App - P3 Campus
Dear Parents and Guardians,
As part of Mercer County School District's commitment to students' safety and mental health, beginning today we are launching an anonymous reporting program, which will allow students and parents to make anonymous reports about concerns of safety or student wellness. Our program is student-focused, as opposed to crime focused, meaning it is a tool for alerting caring adults about students who need help-not snitching. This is part of our continuous effort to increase campus and student safety, and provide students with a safe, completely anonymous outlet to share concerns.
Students can use our new P3 Campus app to report: bullying, suicide concerns, depression, sexting, stealing, threats, cutting, abuse, dating and domestic violence, fights, drugs, alcohol, weapons or other types of dangerous situations that threaten their safety or the safety of others. Their reports will be addressed by a trained team of school officials and law enforcement, when necessary.
When you or your student have a concern, you can go to P3Campus.com on your computer, tablet, or laptop- or you can download the free P3 Campus mobile app-- and make a 100% anonymous report in less than five minutes.
The use of anonymous reporting apps in state programs like Safe2Tell Colorado have proven to be successful in providing the tools and information needed for school officials and to proactively address concerning behaviors, potential incidents of violence, and other harmful situations on campus before they develop. We look forward to working with you and your student to continue making the Mercer County Schools safe.
