ALERRT Mission: To provide the best research-based active shooter response training in the nation.

ALERRT Vision: Training and research that saves lives and protects communities.

The ALERRT Center at Texas State University was created in 2002 as a partnership between Texas State University, the San Marcos, Texas Police Department and the Hays County, Texas Sheriff’s Office to address the need for active shooter response training for first responders. In 2013, ALERRT at Texas State was named the National Standard in Active Shooter Response Training by the FBI.

Training Capacity

Since 2002, ALERRT at Texas State has been awarded more than $126 million in state and federal grant funding, and has trained more than 248,000 law enforcement, fire, EMS, and Emergency Management officials nationwide. We have also trained more than 900,000 personnel in our Civilian Response to Active Shooter Events (CRASE) Avoid-Deny-Defend awareness program.

While much of the training is delivered on-site in cities around the country, ALERRT also has a multimillion-dollar training facility in San Marcos for advanced active shooter response training.


In addition to in-depth after-action lessons learned through partnerships with agencies who have been involved in headline-making active shooter situations, ALERRT has established a criminal justice research department to evaluate and enhance the overall understanding of active shooter events and assist in improving law enforcement best practices.


Utilizing the train-the-trainer model, the ALERRT curriculum has been adopted by numerous states and agencies as their standard active shooter training. These states include Mississippi, Alabama, Oklahoma, Texas, Iowa, Louisiana, Maryland, Georgia, and Virginia, to name a few. In addition, the New York City Police Department, Miami Police Department, Dallas Police Department, Houston Police Department, San Antonio Police Department, Memphis Police Department, and the Atlanta Police Department are among the major cities across the nation, who have adopted the ALERRT curriculum as their standard.

National Integrated Response Conference

ALERRT hosts a national integrated response conference each fall. The ALERRT Active Shooter Integrated Response Conference is the only national conference bridging the law enforcement, Fire and EMS responses to active shooter / attack events. The 2018 conference merged the three disciplines (Police, Fire and EMS), and for the first time, included emergency room physicians to build integration and coordinated command centers, creating stronger local, regional, state and national active shooter response preparedness. Based on recent active shooter / intentional mass injury events in the United States, the reality is that saving victims’ lives does not end in an ambulance or at the doors of the emergency department.
