In the policy’s own words
What the policy says
TrojansAlert definition and channelsverbatim
TrojansAlert is an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message and email.
- — Defines the system as a two-channel (text and email) tool operated by university officials.
Authorized senders and contentverbatim
When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information.
- — Limits activation to pre-authorized senders and frames messages as action-oriented instructions.
Clery geography vs. patrol-boundary crime alertsverbatim
Any time a serious crime is reported within USC's patrol boundaries (approximately 2-mile radius around campus) but not within Clery geography, DPS files it as a crime alert.
- — Distinguishes Clery timely warnings (inside Clery geography) from crime alerts (inside the broader ~2-mile patrol boundary).
At a glance
How this policy works
- When it activates
- TrojansAlert is activated during an emergency by authorized USC senders to deliver real-time updates and instructions. Under Clery, timely warnings are issued for Clery crimes within a Clery reportable location that represent a serious or continuing threat, and emergency notifications upon confirmation of a significant emergency or dangerous situation on campus involving an immediate threat to health or safety; serious crimes inside DPS's ~2-mile patrol boundary but outside Clery geography are issued as crime alerts.
- Who decides
- Authorized USC senders within the Department of Public Safety send TrojansAlert messages; the decision to issue a timely warning is made case-by-case by one or more pre-identified USC officials under USC's Policy and Procedures for Issuing a Timely Warning.
- Timeliness standard
- Authorized senders are described as able to instantly notify the community when an emergency occurs; Clery emergency notifications are issued upon confirmation of a significant emergency or dangerous situation involving an immediate threat to health or safety on campus.
- Emergency notification vs. timely warning
- Geography-driven three-part framework: emergency notifications for confirmed significant emergencies/immediate threats on campus; Clery timely warnings for serious/continuing-threat crimes within Clery geography; and crime alerts for serious crimes inside DPS's ~2-mile patrol boundary but outside Clery geography.
- Testing cadence
- USC tests the TrojansAlert system periodically; the Annual Security and Fire Safety Report (published on or before October 1 annually) documents the institution's emergency-notification and testing policies. Exact published cadence was not reproduced in accessible sources.
- Scope & limits
- TrojansAlert activation is limited to authorized USC senders. Timely warnings are limited to Clery crimes within Clery geography that pose a serious or continuing threat; crimes outside Clery geography but within DPS's ~2-mile patrol boundary are handled as crime alerts; emergency notifications require a confirmed immediate threat on campus.

Analysis
Reading the policy
TrojansAlert is USC's emergency notification channel. The Department of Public Safety describes it as "an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message and email." DPS adds that "When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information" — emphasizing that activation is limited to pre-authorized senders and that messages are action-oriented.
Enrollment is automatic for the core population and opt-in for everyone else. Current students are automatically enrolled and no action is required; faculty and staff are encouraged to add their cell phone numbers in Workday (and designate them as the USC Emergency/Safety Alerts number) so they receive text alerts, which DPS calls the fastest and most direct way to reach individuals in an emergency. All recipients who are not current students, faculty, or staff — including parents, community members, and alumni — must sign up annually to keep receiving alerts. (In a September 2024 update to how TrojansAlerts are distributed, DPS reiterated these enrollment mechanics.)
On Clery framing, USC's Department of Public Safety distinguishes between two notice types tied to geography. The Clery Act requires USC to notify the public of certain crimes occurring within Clery-designated geography; these notices are called timely warnings, issued in response to Clery crimes within a Clery reportable location that represent a serious or continuing threat to the campus community, determined case-by-case by pre-identified USC officials under USC's policy and procedures for issuing a timely warning. Separately, any time a serious crime is reported within USC's patrol boundaries — approximately a two-mile radius around campus — but not within Clery geography, DPS files it as a crime alert. As one of the nation's largest university public-safety agencies with more than 300 full-time members operating 24/7, USC's wide patrol footprint makes this geography-driven warning/alert distinction operationally significant.
Emergency notifications under the Clery Act are issued upon confirmation of a significant emergency or dangerous situation involving an immediate threat to the health or safety of USC faculty, staff, employees, students, patients, and visitors occurring on campus; the Annual Security and Fire Safety Report is published on or before October 1 each year for the preceding three years. Scope is therefore bounded by the authorized-sender requirement and the Clery serious/continuing-threat and immediate-threat standards, with the timely-warning vs. crime-alert split keyed to whether a crime falls inside Clery geography or merely inside DPS's broader patrol area.
Takeaways
Key findings
TrojansAlert is USC's two-channel (text and email) emergency notification system, operated by the Department of Public Safety.
Activation is limited to authorized USC senders, who deliver real-time, action-oriented instructions (where to go, what to do, whom to contact).
Current students are automatically enrolled; faculty/staff add cell numbers in Workday; parents, community members, and alumni must sign up annually.
USC draws a geography-based distinction: timely warnings for serious/continuing-threat crimes inside Clery geography, and crime alerts for serious crimes inside DPS's ~2-mile patrol boundary but outside Clery geography.
Clery emergency notifications are issued upon confirmation of a significant emergency or dangerous situation posing an immediate threat to health or safety on campus, documented in the Annual Security and Fire Safety Report.
