Policing in an educational environment and is a unique experience where we join as partners with educators to ensure an environment that is conducive to the learning process.


The Officers of the TISD Police Department are exceptional in the levels of professionalism they demonstrate in their commitment to shared values of moral and ethical conduct, and in their interaction with students and staff. Our officers are fully certified Texas Peace Officers who have the same authority as other local law enforcement officers. Our staff is highly trained and qualified to meet the needs of all law enforcement efforts of prevention, intervention, and enforcement with a focus on creating the safest learning environment possible for our students, staff, and visitors. 


Through Crime Stoppers' P3 Tips App by Anderson Software, anyone can use their iOS or Andriod mobile phone to provide crime-solving information, submit photos of suspects and videos of crimes, and have two-way conversations with Crime Stoppers about the crime, their tip, and a reward, ALL WHILE REMAINING ANONYMOUS. The multi-lingual P3 Tips App is a secure, anonymous, and efficient means of safely communicating with Crime Stoppers.

The two-way dialog feature of the P3 Tips App allows a "Tipster" to provide additional information, check the status of the investigation, or learn if a reward has been authorized, as well as provides the means for Crime Stoppers to ask questions of or provide updates to a Tipster, all through an encrypted interface that protects the Tipster's anonymity.
