New 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.

In order for the Illinois Department of Public Health (IDPH) and the Governor’s Office to allow our student athletes to “Return To Play”, there are strict guidelines they are requiring all school districts to follow.  Please CLICK THE LINK BELOW so you are aware of the protocols that will be in place as our students begin competing once again.  We understand that many of the requirements can be an inconvenience, but the important thing is our students will once again be able to participate in the activities they truly enjoy.  Please do your part in following the required guidelines so the State does not take this opportunity away from our students.

Mercer County School District News

July 23, 2021

Dear Mercer County School District Students, Staff, and Families,


The health and safety of our students and staff is our top priority, so we want to share information from the Centers for Disease Control and Prevention (CDC), the Illinois State Board of Education (ISBE), the Illinois Department of Public Health (IDPH), and the Mercer County Health Department. Please see the links in the accompanying Return to School document.


The most common question we receive relates to masking. While masking is recommended for unvaccinated individuals, it is not required at this time, except on school buses, as it was during the 2020-2021 school year. School districts have been given greater latitude to make decisions based on local conditions. Given these parameters and the current conditions, Mercer County Schools will return to full in-person learning utilizing the normal school day. Parents wishing to choose remote learning will need to complete the medical certification form linked in the Return to School draft. We will continue to practice as many health and safety measures as practical such as hand washing, daily symptom checks, and enhanced cleaning; however, those practices that were most disruptive to our educational mission: pods, staggered passing times, or one-way hallways will not.



We will continue to closely monitor local conditions and the broader recommendations regarding coronavirus from the above organizations. Updates and changes are likely as we experienced last year, but our staff and students are resilient, and we are looking forward to starting the 2021-2022 school year under much more normal conditions. Thank you for your support in helping to keep our school community healthy and in-person.
