District Safety & Security

Celina ISD is committed to ensure that all of its students, staff, and visitors are safe and secure while on campus or while attending any of its many District approved functions. For several years, Celina ISD has devoted significant resources to improve the safety and security around all of its facilities. Some of these improvements include additional security cameras, fencing, access control systems, security vestibules, and alarm systems.


The Celina ISD Safety & Security Department's mission is to support the District's overall Mission Statement by providing a safe and secure learning and teaching environment for all staff and students. This will be accomplished by using "Best Practices for Emergency Operations" as directed by FEMA, Homeland Security, The State of Texas, as well as interaction with state and local public safety authorities. The Celina ISD Public Safety Department will utilize internal resources from the CISD Police Department and staff members who are trained and certified in emergency operations, as well as 3rd party public and school safety authorities and consultants.


The Celina ISD Police Department is an independent Texas Police agency located within Celina ISD. The Celina ISD Police Department's goal is to ensure a safe and secure school environment.

School safety drills are conducted using the I LUV U GUYS national safety program. A list of those drills can be found here.
