No school administrator wants to imagine their campus becoming the site of the next tragedy. Yet every time a school shooting makes headlines, the same question echoes through boardrooms and faculty meetings: "Could this happen here? Are we prepared?"

The uncomfortable truth? Most schools aren't as prepared as they think they are.

After four decades protecting lives—from nuclear weapons facilities to combat zones to university campuses—and now consulting with K-12 districts and universities nationwide on campus safety programs, I've observed consistent patterns in how schools approach active shooter preparedness. Some get it right. Most don't.

The schools that fail aren't necessarily under-resourced or uncaring. Often, they're making critical strategic mistakes that create the illusion of preparedness while leaving students and staff dangerously vulnerable.

This article identifies the seven most common—and most dangerous—mistakes schools make in active shooter preparedness, and more importantly, provides actionable solutions to fix them before tragedy strikes.

School Active Shooter Preparedness: 7 Critical Mistakes Districts Make (And How to Fix Them)

The Current State of School Safety in 2025

Let's establish baseline context. School shootings remain statistically rare—students are safer at school than almost anywhere else. But when they occur, the devastation is catastrophic, and the legal, financial, and emotional aftermath can destroy communities and careers.

The Numbers:

Between 2000 and 2023, the FBI documented hundreds of active shooter incidents across all locations, with educational institutions representing a significant portion. These incidents demonstrate consistent patterns:

Most perpetrators are current or former students
Warning signs were observable in advance in the vast majority of cases
Bystanders knew about concerning behaviors but often didn't report them
Response time from initial shots to resolution averages 10-15 minutes—too long to rely solely on law enforcement

The Regulatory Landscape:

States are increasingly mandating specific school safety measures:

Active shooter drills: Now required in most states, with varying specifications on frequency and format
Threat assessment teams: Growing number of states requiring formal threat assessment programs
Safety audits: Regular security assessments becoming standard requirements
Reporting systems: Anonymous reporting mechanisms required in many jurisdictions

The ASIS International School Security Standard—expected to be finalized in 2025—will provide comprehensive framework for K-12 security, creating de facto national standard even without federal mandate.

The Liability Reality:

Schools can be held liable for foreseeable violence they failed to prevent. "We didn't think it could happen here" is not a legal defense. Courts expect schools to:

Implement reasonable security measures
Train staff on emergency response
Conduct threat assessments on concerning behaviors
Maintain and practice emergency plans
Document security decision-making

Understanding this context, let's examine where schools go wrong—and how to correct course.

Mistake #1: Focusing Only on Response, Not Prevention

The Problem:

Walk into most school security planning meetings, and the conversation immediately turns to response: lockdown procedures, evacuation routes, communication systems, law enforcement coordination. All important—but fundamentally reactive.

Schools invest heavily in what to do after shots are fired while investing minimally in preventing someone from deciding to shoot in the first place.

This is backwards. As my experience conducting threat assessments for schools and universities has proven repeatedly: the best response to an active shooter is preventing them from becoming one.

Why This Happens:

Response is tangible. You can buy door barricades, install panic buttons, conduct lockdown drills. Prevention is harder—it requires changing culture, training staff, establishing systems, conducting investigations. Response feels like doing something. Prevention feels like... talking about doing something.

Additionally, response addresses the dramatic, terrifying scenario that dominates public imagination. Prevention addresses the mundane, uncomfortable work of monitoring concerning student behavior—less cinematic, but infinitely more effective.

The Fix:

Implement comprehensive behavioral threat assessment programs that identify concerning students before they reach crisis point. This requires:

1. Establishing Threat Assessment Teams:

Create multidisciplinary teams including:

School administrators
Mental health professionals (counselors, psychologists)
School resource officers or security personnel
Teachers who can provide classroom observations
Legal advisors who understand student rights

These teams don't just respond to threats—they proactively identify students showing warning signs and coordinate intervention before situations escalate. My Campus Under Siege book provides detailed frameworks for establishing and operating school-based threat assessment teams.

2. Training All Staff on Warning Signs:

Every teacher, counselor, coach, cafeteria worker, and bus driver should recognize behavioral indicators:

Social isolation combined with grievance
Fixation on violence or previous school shooters
Communications suggesting violent intent
Research into weapons or attack methods
Pathway behaviors (planning, preparation, surveillance)
Concerning social media posts
Dramatic behavioral changes

Training isn't one-time—annual refreshers ensure continued vigilance.

3. Creating Reporting Cultures:

Students typically know about concerning peers before adults do. But they won't report unless:

Multiple, accessible reporting mechanisms exist (hotlines, online forms, in-person options)
Anonymous reporting is available
They trust that reports will be taken seriously
They see consequences when threats are real but support when peers are struggling

4. Integrating Prevention with Response:

Prevention and response aren't separate—they're integrated. Threat assessment informs emergency planning. Who are the highest-risk students requiring enhanced monitoring? What scenarios are most likely given known threats? How do security measures address specific identified risks?

Prevention-focused schools don't abandon response planning—they enhance it with intelligence about actual threats rather than hypothetical scenarios.

Mistake #2: Inadequate or Non-Existent Threat Assessment Protocols

The Problem:

Many schools either lack formal threat assessment protocols entirely or have procedures that exist only on paper without actual implementation. When concerning behaviors arise, responses are ad-hoc, inconsistent, and often inadequate.

Without structured protocols, schools miss opportunities for early intervention. Students exhibiting warning signs may receive informal conversations but no systematic assessment, monitoring, or intervention. By the time situations become critical, options have narrowed significantly.

Research Evidence:

The Secret Service's study "Averting Targeted School Violence" analyzed plots against schools and found that in most cases:

Someone knew about the student's concerning behavior
Warning signs were observable weeks or months in advance
No formal threat assessment was conducted
Opportunities for intervention were missed

Research on school threat assessments consistently shows that structured assessment protocols identify high-risk situations earlier and more accurately than informal approaches.

The Fix:

Implement evidence-based threat assessment protocols following FBI, Secret Service, and Department of Homeland Security guidelines:

1. Adopt Structured Assessment Frameworks:

Use validated threat assessment tools such as:

Comprehensive School Threat Assessment Guidelines (CSTAG): Developed by University of Virginia researchers, widely adopted
Salem-Keizer System: Evidence-based protocol used successfully across multiple districts
Behavioral Threat Assessment Framework: FBI-recommended approach

These frameworks provide systematic processes for:

Receiving and triaging reports
Conducting investigations
Evaluating risk levels
Determining appropriate interventions
Monitoring ongoing cases

2. Define Clear Thresholds:

Establish specific criteria for:

What behaviors trigger assessment: Direct threats, conditional threats, concerning communications, pathway behaviors, concerning social media
Assessment urgency levels: Immediate (imminent danger), priority (24-48 hours), routine (one week)
Risk classifications: Low (monitoring), moderate (intervention), high (intensive management), imminent (emergency response)

Clarity prevents both over-reactions to minor concerns and under-reactions to serious threats.

3. Document Everything:

Comprehensive documentation protects schools legally and improves program quality:

Initial report details
Investigation findings
Assessment methodology and conclusions
Intervention decisions and rationale
Monitoring activities
Case outcomes

Documentation demonstrates that schools took reasonable steps to assess and manage known threats—critical for liability protection.

4. Coordinate with Law Enforcement:

Schools shouldn't conduct threat assessments in isolation. Establish protocols with local law enforcement for:

When to notify police (imminent threats, weapons possession, criminal activity)
Information sharing procedures (balancing student privacy with safety)
Joint threat assessment when appropriate
Coordinated intervention planning

My experience as an LAPD officer taught me that early law enforcement coordination often prevents situations from reaching criminal threshold while maintaining student privacy when appropriate.

Mistake #3: Poorly Trained Staff and Traumatic Drills

The Problem:

Many schools approach active shooter preparedness with two extremes: either minimal training that leaves staff unprepared, or hyper-realistic drills that traumatize students and staff without improving actual preparedness.

The Training Gap:

Staff receive one-time active shooter training during orientation, then nothing for years. When emergencies occur, they've forgotten procedures, don't know their specific roles, and make critical errors under stress.

Alternatively, some schools conduct elaborate lockdown drills complete with simulated gunshots, fake blood, and actors playing wounded victims—traumatizing students while providing minimal actual learning.

Research on Drill Trauma:

Recent studies show that overly realistic active shooter drills can:

Create anxiety and fear in students
Trigger trauma responses in students with PTSD or prior violence exposure
Reduce sense of school safety
Provide minimal improvement in actual response capability

The goal is preparedness without trauma—possible but requiring thoughtful design.

The Fix:

Implement graduated training and age-appropriate drills:

1. Comprehensive Staff Training:

All staff should receive annual training on:

Run-Hide-Fight/ALICE protocols: Understanding response options
Communication procedures: How to alert others, communicate with law enforcement
Evacuation vs. lockdown decision-making: When to evacuate, when to shelter-in-place
Special needs considerations: How to assist students with disabilities
Post-incident procedures: What happens after threat resolution

Training should include:

Classroom instruction
Tabletop exercises
Hands-on practice with doors, locks, barricades
Decision-making scenarios

2. Age-Appropriate Student Training:

Different developmental stages require different approaches:

Elementary (K-5):

Focus on listening to adults
Simple concepts: "safe spaces," "quiet game"
No mention of guns or shooters
Practice through games and stories

Middle School (6-8):

Age-appropriate discussion of why drills occur
Basic Run-Hide-Fight concepts
Emphasis on options and decision-making
De-emphasis on graphic details

High School (9-12):

Comprehensive discussion of active shooter realities
Full Run-Hide-Fight/ALICE training
Scenario-based learning
Student leadership in emergency response

3. Trauma-Informed Drills:

Conduct drills that prepare without traumatizing:

Never:

Use simulated gunfire or explosions
Use fake blood or staged injuries
Surprise students with unannounced drills
Force students to participate if they have trauma history
Conduct drills right before holidays/weekends when students can't process

Always:

Announce drills in advance
Provide opt-out options for traumatized students
Debrief after drills
Focus on successful actions, not fear
Make drills routine, not dramatic

Training videos and resources can supplement live training, providing consistent messaging across all staff.

4. Multiple Drill Formats:

Vary drill formats to build different skills:

Tabletop exercises: Verbal walkthrough of scenarios
Evacuation drills: Practice orderly evacuation
Lockdown drills: Practice shelter-in-place procedures
Communication drills: Practice alert systems
Full-scale exercises: Comprehensive simulation with law enforcement (staff only, after hours)

Frequency matters—quarterly drills maintain skills without creating constant anxiety.

Mistake #4: Weak Physical Security and Access Control

The Problem:

Many schools have invested in security technology—cameras, door locks, visitor management systems—but implement them ineffectively or inconsistently. Others lack basic physical security measures entirely, relying primarily on policies and procedures.

Physical security won't stop determined attackers alone, but it creates critical delays, limits movement, and provides warning time that enables effective response.

Common Failures:

Locked exterior doors routinely propped open for convenience
Visitor sign-in procedures not enforced
Back and side doors left unsecured
No vestibule or screening at main entrance
Security cameras installed but rarely monitored
Interior classroom doors that can't be locked from inside
No visual barriers blocking view into classrooms

These gaps transform security systems from effective barriers into expensive window dressing.

The Fix:

Implement layered physical security:

1. Perimeter Security:

Create clear boundaries and control points:

Fencing: Define school property, direct visitors to main entrance
Signage: Clear wayfinding to designated visitor entrance
Monitoring: Cameras covering all exterior doors and approaches
Limited access points: Single controlled entrance during school hours, other doors locked and alarmed

2. Entrance Security:

Main entrance should include:

Secure vestibule: Visitors cannot access main building without screening
Visual screening: Staff can see visitors before buzzing them in
Visitor management: ID scanning, badge printing, background checks
Duress alarms: Panic buttons for reception staff
Hardened design: Reinforced glass, secure door hardware

3. Interior Security:

Once inside perimeter, additional measures:

Classroom door locks: Operable from inside without keys (compliance with fire codes)
Visual barriers: Ability to cover door windows during lockdown
Hardening options: Door barricades, reinforced door frames (with fire marshal approval)
Communication systems: PA, intercoms, mass notification
Safe zones: Identified locations for shelter-in-place

4. CPTED Principles:

Crime Prevention Through Environmental Design improves security through:

Natural surveillance: Design that enables observation (windows, sightlines, lighting)
Natural access control: Design that guides traffic flow and restricts access naturally
Territorial reinforcement: Clear distinction between public and private space
Maintenance: Well-maintained facilities signal care and attention

My book Locked Down: The Access Control Playbook provides comprehensive guidance on implementing effective physical security measures in educational environments.

5. Regular Testing and Maintenance:

Security systems require ongoing attention:

Monthly testing of door locks
Quarterly testing of camera systems
Annual testing of alarm systems
Regular staff accountability for security procedures
Periodic penetration testing (attempting unauthorized entry)

Mistake #5: No Community Partnerships or Law Enforcement Coordination

The Problem:

Schools often operate security programs in isolation, treating partnerships with law enforcement, mental health agencies, and community resources as optional rather than essential.

When emergencies occur, schools discover that:

Law enforcement doesn't have current building layouts
First responders don't know school procedures
Communication systems aren't compatible
Roles and responsibilities weren't clarified
No established relationships exist to facilitate coordination

Crisis is the wrong time to exchange business cards.

The Fix:

Build comprehensive community partnerships:

1. Law Enforcement Coordination:

Establish formal relationships with:

Local police departments
Sheriff's offices
School resource officer (SRO) programs
FBI field offices (for major threats)

Coordination Activities:

Facility tours: Annual walk-throughs providing current layouts, access points, evacuation routes
Joint training: Combined exercises between school staff and law enforcement
Communication protocols: Shared radio frequencies or systems, emergency contact lists
Threat information sharing: Agreements on when and how to share threat intelligence
Memorandums of understanding (MOUs): Formal agreements on roles, responsibilities, response protocols

2. Mental Health Partnerships:

Connect with community resources:

Local mental health agencies
Crisis intervention services
Hospital psychiatric departments
Private practitioners willing to provide consultation
Mobile crisis response teams

These partnerships provide:

Emergency mental health services
Consultation on threat assessments
Treatment referrals for identified students
Training on mental health crisis recognition

3. Emergency Management Coordination:

Integrate with broader emergency systems:

County/city emergency management agencies
Fire departments
Emergency medical services
Public health departments
Red Cross or equivalent organizations

This coordination ensures:

Schools included in community emergency plans
Access to emergency resources during large-scale incidents
Unified command structures during multi-agency response

4. Business and Community Resources:

Engage local stakeholders:

Security companies providing volunteer support
Medical professionals available for emergencies
Mental health professionals donating services
Faith communities offering counseling and support
Businesses providing emergency supplies or facilities

These partnerships provide resources schools couldn't afford independently while strengthening community investment in school safety.

Regular partnership meetings—quarterly minimum—maintain relationships and update coordination protocols as personnel, procedures, and threats evolve.

Mistake #6: Ignoring Behavioral Warning Signs and Student Mental Health

The Problem:

School shooting prevention fundamentally isn't a security problem—it's a mental health and behavioral intervention problem. Security measures provide barriers and response capabilities, but addressing underlying causes prevents violence from occurring.

Many schools recognize this intellectually but fail operationally—treating security and mental health as separate domains rather than integrated systems. Security staff don't receive mental health training. Counselors don't receive threat assessment training. Neither coordinates effectively with the other.

Meanwhile, students exhibiting warning signs receive inadequate support:

Limited counseling services with months-long waitlists
Disciplinary responses to mental health crises
Suspensions that isolate troubled students further
Insufficient crisis intervention capabilities
No systematic monitoring of high-risk students

The Research:

FBI research consistently shows that school shooters exhibit observable warning signs:

Social dynamics: Isolation, bullying (as victim or perpetrator), deteriorating peer relationships
Mental health: Depression, anxiety, psychosis, suicidal ideation
Behavioral changes: Academic decline, attendance problems, aggressive outbursts, rule violations
Communications: Direct or veiled threats, violent fantasies, identification with previous shooters
Pathway behaviors: Research, planning, acquiring weapons, surveillance

These aren't just behavioral problems—they're cries for help that schools must recognize and address.

The Fix:

Integrate mental health support with security operations:

1. Comprehensive Counseling Services:

Ensure adequate mental health support:

Counselor ratios: Meet recommended ratios (1:250 is gold standard, many schools have 1:500+)
Crisis counselors: Designated staff available for emergency mental health situations
External partnerships: Contracts with community mental health agencies for supplemental services
Telehealth options: Virtual counseling expands access

2. Training Integration:

Train both security and counseling staff on the intersection of their roles:

Security staff: Training on mental health crisis recognition, de-escalation, appropriate responses
Counseling staff: Training on threat assessment fundamentals, warning signs, when to involve security/law enforcement
Joint training: Combined sessions building shared understanding and relationships

3. Student Support Systems:

Implement proactive mental health support:

Peer mentoring: Trained students providing support to isolated peers
Check-in systems: Counselors regularly connecting with high-risk students
Anonymous support requests: Ways students can request help confidentially
Positive behavioral interventions: Proactive approaches rather than purely punitive discipline

4. Threat Assessment Integration:

Connect behavioral observation with formal assessment:

Teachers report concerning behaviors to counselors
Counselors assess whether behaviors warrant threat assessment team review
Threat teams include mental health professionals in all assessments
Interventions prioritize treatment and support alongside security measures

My training in behavioral threat assessment and management (BTAM) emphasizes this integration—effective threat assessment requires understanding both security operations and human psychology. Neither alone is sufficient.

Mistake #7: Insufficient Emergency Communication Systems

The Problem:

During active shooter events, seconds matter. Rapid notification can mean the difference between targeted response and mass casualty. Yet many schools rely on inadequate communication systems:

PA systems only: Can't reach everyone, especially in noisy areas or during outdoor activities
Email/text delayed: Messages sent but not received immediately
No integration: Security cameras, door locks, and communication systems operate independently
Single point of failure: One system disabled renders school unable to communicate
No backup power: Systems fail when power is cut
Unclear messaging: Staff don't know what different alerts mean

When lockdowns are ordered, staff discover that half the school didn't get the message, students are in transition between classes, and no one knows where the threat is located.

The Fix:

Implement redundant, integrated emergency communication:

1. Multi-Modal Alert Systems:

Combine multiple communication channels:

PA announcements: Campus-wide audio notifications
Mass notification systems: Automated calls/texts/emails to all staff, students, parents
Desktop alerts: Pop-ups on all school computers
Mobile apps: Push notifications to school safety apps
Visual alerts: Flashing lights, digital signage displays
Sirens/horns: Outdoor audio warnings

No single system reaches everyone—redundancy ensures comprehensive notification.

2. Clear, Standardized Messaging:

Develop specific, practiced alert messages:

Lockdown: "Lockdown, lockdown, lockdown. This is not a drill. Secure all rooms immediately."
Evacuation: "Evacuate the building. Proceed to [designated location]."
Shelter-in-place: "Shelter-in-place for [hazard type]. Move away from windows."
All clear: "All clear. Resume normal operations."

Staff must know these messages, understand what each means, and practice appropriate responses.

3. Two-Way Communication:

Enable staff to report back to administration:

Panic buttons: Silent alerts from classrooms indicating distress
Check-in systems: Digital tools allowing staff to report status and location
Dedicated radio channels: Direct communication with security/administration
Emergency apps: Tools enabling reporting, status updates, two-way messaging

Knowing where everyone is and whether they're safe enables better emergency management.

4. Integration with Physical Security:

Connect communication with security systems:

Automated lockdown: Panic button activates both alert system and door locks
Camera integration: Alerts direct security to relevant camera feeds
Access control coordination: Lockdown automatically secures perimeter doors
Visitor management: Emergency alerts notify reception to secure entrance

Integrated systems provide comprehensive security response from single trigger.

5. Regular Testing and Training:

Communication systems require maintenance and familiarity:

Monthly testing: Verify all communication channels functional
Quarterly drills: Practice using systems under emergency conditions
Annual system evaluation: Assess effectiveness and identify needed improvements
After-action reviews: Learn from actual emergency activations

Bringing It All Together: Comprehensive School Safety Programs

These seven mistakes aren't isolated failures—they're symptoms of fragmented, reactive approaches to school safety. Fixing one mistake while ignoring others provides minimal improvement.

Effective school safety requires comprehensive, integrated programs that combine:

Prevention:

Threat assessment teams
Mental health support
Behavioral intervention
Student and staff training
Reporting systems and culture

Physical Security:

Access control
Perimeter security
Interior hardening
Technology integration
CPTED principles

Response Planning:

Emergency procedures
Communication systems
Law enforcement coordination
Evacuation and lockdown protocols
Medical emergency response

Community Partnerships:

Law enforcement relationships
Mental health resources
Emergency management coordination
Business and community support

Continuous Improvement:

Regular program evaluation
Incident analysis and lessons learned
Evolving threats and best practices
Training updates
System testing and refinement

Schools that excel at safety don't do one thing well—they do many things competently and coordinate them effectively.

My work establishing comprehensive campus safety programs across educational institutions has proven repeatedly: integrated approaches prevent violence while fragmented approaches merely react to it.

Conclusion: Moving from Compliance to Excellence

Most schools approach active shooter preparedness as compliance exercise: check the required boxes, conduct mandated drills, file necessary reports. This produces minimal adequacy—better than nothing but far from excellence.

The seven mistakes outlined in this article represent the gap between compliance and excellence:

Compliance schools focus on response; excellent schools emphasize prevention
Compliance schools have threat assessment on paper; excellent schools operationalize it
Compliance schools conduct traumatic drills; excellent schools train effectively without trauma
Compliance schools install security systems; excellent schools use them properly
Compliance schools operate independently; excellent schools build partnerships
Compliance schools address behavior punitively; excellent schools integrate mental health support
Compliance schools have basic communication; excellent schools have redundant, integrated systems

Which type of school do you lead?

After forty years protecting lives in environments ranging from nuclear facilities to combat zones to educational campuses—and consulting with schools nationwide on safety programs—I can state unequivocally: excellence in school safety isn't about spending more money. It's about spending money strategically, training staff effectively, integrating systems thoughtfully, and maintaining vigilance consistently.

Schools that do these things prevent tragedies. Schools that don't become tragedies.

The choice—and the responsibility—rests with educational leaders willing to acknowledge where their programs fall short and commit to fixing them before crisis forces the issue.

The question isn't whether your school will face threats. The question is whether you'll have systems in place to identify and manage those threats before they materialize into violence.

Will you?
