Guide to effective school lockdowns: procedures, drills and more

What is a school lockdown?

A school lockdown is a defined safety procedure that all school residents are asked to follow in response to an immediate internal or external threat. Schools on lockdown will suspend all regular activities, lock all access points and shelter all students and staff in a secure location.

When should schools lock down campuses?

Lockdowns in schools are designed to address various types of internal and external threats:

• Active shooters: Someone inside or outside the school is carrying out a violent attack.
• Unauthorized intruders: An unknown person has entered the school without permission.
• Aggressive persons: Someone inside the school is exhibiting threatening behavior.
• Reports of weapons: A person inside the school is brandishing a deadly weapon.
• Dangerous animals: A potentially aggressive animal has entered the school.
• Nearby police activity: A dangerous situation is developing near the school.
• Natural disasters: Fires, storms, floods or earthquakes that pose a threat to the school.
• Civil disturbances: Riots or protests in the nearby area that pose a threat to the school.
• Communication loss: Communications systems may be knocked offline by malicious actors, power outages, equipment failure and natural disasters, leaving the school vulnerable to physical and cybersecurity attacks.

Soft lockdowns vs. hard lockdowns

School lockdowns can be divided into two types: soft and hard lockdowns. Each procedure is designed to protect students and staff from specific threats, thereby minimizing disruptions and ensuring the effectiveness of the school’s commercial security systems. 

What is a soft lockdown?

A soft lockdown is a proactive safety measure designed to address non-imminent threats, such as reports of an intruder in the building or law enforcement activity near the school. The goal of a soft lockdown is to safeguard students and staff without entirely halting all school activities.

During a typical school soft lockdown, all exterior access points will be locked, security staff will be on high alert and communication will be established with local authorities. The situation will be closely monitored, while normal activities, such as classes, will continue. 

What is a hard lockdown?

A hard lockdown in school is a reactive safety measure intended to address an immediate threat inside the property, like an active shooter or dangerous animal. Hard lockdowns are more involved, generally requiring all activities and communications to be minimized.

During a hard lockdown, all exterior and interior access points will be secured, and students and staff will remain in designated safe areas within the building. Emergency responders will be promptly notified, while movement and communications will be limited to ensure safety and control.

School lockdown procedures

During a school lockdown, everyone on campus is instructed to shelter in a secure location, such as a classroom or office. All doors and windows are locked and access to the campus is restricted to police and emergency services. No one is allowed to leave until the lockdown is officially lifted.

School administrators and security teams will outline these procedures in the school’s Emergency Operations Plan (EOP), taking into account factors like school size, potential threats and the configuration and use of school security systems.

Below are the steps included in a standard school lockdown procedure:

1. Identify the threat

A potential threat will be identified through manual observation, witness reports or security system data, warning security teams and school administrators of the unfolding incident. In some cases, security technologies like motion sensors or AI-powered cameras may trigger alerts and engage school lockdown procedures automatically to help enact swift responses.

When an alert is triggered, an announcement will be made to all individuals on campus informing them that the school is in lockdown. This may include an automated or manual verbal notification, along with an emergency alarm tone broadcast over the intercom system. 

2. Lock all access points

Once the school lockdown is announced, all relevant access points will be locked and secured. During a soft lockdown, some internal doors and windows may remain accessible, but during a hard lockdown, all external and internal access points will be fully secured.

In some cases, staff or security teams must manually secure all access points, while other schools use integrated lockdown security systems to automate the process. In these situations, smart locks, access control systems and rolling shutters are often connected to security tools like cameras and sensors, enabling them to lock automatically in response to a threat.

3. Shelter students and staff

When school lockdown is activated, students and staff will be guided to the nearest secure location, as outlined in the school’s EOP. Secure spaces will typically be windowless offices and classrooms or similar rooms within the building, equipped with lockable access points, reinforced walls, well-stocked first aid supplies and secure communications devices.

For the duration of the school lockdown, students and staff must remain in their classrooms, mute all personal devices and limit their movement where possible. Lights should be turned off and people must stay away from windows and doors, keeping noise to a minimum. 

4. Communicate with local authorities

Establishing and maintaining a secure line of communication with local authorities is a critical step during any school lockdown. The school’s EOP outlines how authorities will be alerted to the lockdown and kept informed with relevant updates throughout the emergency. 

During a standard school lockdown procedure, the school’s internal telephone system will be disabled to prevent communications from being intercepted or intruders from being alerted to secure locations. School administrators may contact police directly via email, radio or a secure phone line. School security systems may also send an automated request for response.

5. Observe the situation

Teachers and security staff will observe the situation while waiting for police and emergency responders to arrive. This may involve sharing new information with colleagues or law enforcement based on visual or auditory evidence, using secure communications solutions.

If the school uses a smart security system, teachers and security teams may be able to remotely view video surveillance feeds, sensor data and access control activity to better assess the situation. In some states, laws like Alyssa’s Law provide local authorities with real-time access to this data during school lockdowns, helping to improve response times. 

6. Wait for the all-clear signal

As part of the school’s EOP, a clear and unmistakable all-clear signal should be established to notify students and staff when a school lockdown has officially ended. This signal is typically a unique alarm tone or a verbal announcement delivered over the school’s intercom or public address system.

In some cases, all-clear notifications may also be sent to personal mobile devices via secure text message or email. Regardless of the delivery method, it is critical that the signal is defined and communicated well in advance of any lockdown drill or actual lockdown in school to avoid confusion and ensure a smooth transition back to normal operations.

How lockdown drills help improve school safety

Lockdown drills at school are one of the most effective tools schools can use to prepare students and staff for emergency situations. These drills simulate the conditions of a real school lockdown, providing everyone on campus with an opportunity to practice critical steps in a controlled and safe environment.

By conducting regular school lockdown drills, schools can:

• Reduce fear and panic: Repeated exposure to lockdown procedures helps students and staff remain calm under pressure.
• Reinforce familiarity with procedures: From classroom door locks to hiding locations, drills ensure everyone knows what to do and where to go.
• Test communication systems: Drills expose whether alerts and intercom announcements reach all necessary parties.
• Strengthen coordinated response: Teachers, administrators and security teams can evaluate their timing and teamwork.

While at least 37 states require lockdown drills annually, many schools, especially those with complex layouts or larger populations, conduct lockdown drills more frequently, including elementary school lockdown drills and high school lockdown drills. These routine exercises not only sharpen preparedness but also identify gaps in the school’s EOP.

What should staff do during school lockdowns?

During a school lockdown, teachers and staff are the first line of defense. Their actions during a lockdown in school, whether a routine lockdown drill at school or a real emergency, can help protect lives and reduce chaos. The steps below provide a clear framework for faculty and administrators to follow during a school lockdown drill or an actual event.

1. Secure all doors and lock down the room

Once a lockdown drill or real emergency is initiated, staff must immediately secure their environment. Lock all classroom doors and windows, turn off lights and place covers over any window panes if available. Staff should guide students to move away from windows and doors, staying out of sight and as low to the ground as possible. 

During hard lockdowns, all interior and exterior access points must remain locked and movement should cease entirely until an all-clear signal is issued.

2. Maintain silence and visibility control

Everyone in the room should remain silent. Lights should be turned off and devices like phones must be silenced to avoid drawing attention. Teachers should instruct students to avoid speaking, even in whispers, and not to open the door under any circumstances. Lockdown school drill training often emphasizes the importance of noise control to prevent detection during an active threat.

3. Account for students and communicate securely

Take attendance discreetly once the room is secured. If any students are missing or additional individuals are present, report this using secure communication methods. This might include radios, secure apps or school-issued emergency channels. During real events, communications systems may be disrupted, not just by malicious actors, but also by system overload, power outages or network failures.

School lockdown procedures outlined in the EOP should clarify when and how teachers should use these tools, including alternatives if systems fail.

4. Assist students with special needs

Faculty should know in advance how to support students with mobility issues, sensory sensitivities or other needs. This preparation is essential during both elementary school lockdown drills and high school lockdown drills, where class sizes and age groups differ significantly. Training for lockdowns in schools should always include procedures for inclusive safety.

5. Stay in place until the all-clear Is given

No one should exit their secure location until a pre-identified all-clear signal is received. This could be a unique intercom tone, a verbal message or a secure SMS or email notification. The lockdown drill doesn’t only test readiness, it also makes sure all individuals understand and recognize this crucial signal. No action should be taken until that communication is clearly understood.

6. Leverage security technology

Technology plays a vital role in supporting staff during school lockdowns and drills. Integrated, modern school security systems can provide real-time data to improve decision-making and enhance safety protocols:

• Access control dashboards allow authorized personnel to remotely secure doors and observe open access points during soft lockdowns, hard lockdowns or drills.
• Live camera feeds from security systems give security teams and, in some states, law enforcement real-time visibility into what’s happening inside the school.
• Emergency notification systems can issue instant alerts across intercoms, phones and connected devices, ensuring every room is informed.
• Integrated platforms bring video, access and communication tools into one interface to enable faster, more informed responses during school lockdown drills or real emergencies.

Navigating school lockdowns outside of normal class periods 

School lockdowns can occur at any time, not just during structured classroom periods. Because threats don’t follow a schedule, it’s essential that lockdown drills at school account for less predictable parts of the day. Situational planning helps ensure that students, staff and visitors know how to respond regardless of their location on campus. 

Modern school security systems, including video security, access control and intercoms, support these efforts by offering broad visibility and fast communication across school grounds.

During lunch or recess

Lockdowns during lunch or recess present unique challenges because students are often scattered across cafeterias, playgrounds and other open areas. When a school lockdown is called, supervising staff must act quickly to guide students to the nearest secure room or safe zone. Schools should pre-identify lockdown-safe areas near cafeterias and outdoor spaces and ensure these areas are stocked with emergency supplies and secure communications tools.

Access control systems play a crucial role here by allowing staff to remotely lock or unlock doors as students enter buildings. School emergency alert systems can also push lockdown notifications through intercoms or mass notification apps to reach outdoor staff. Regular lockdown drills in school environments should include lunch and recess periods to help students and staff respond calmly under pressure.

During hallway transitions or gym class

When lockdowns occur during class transitions or physical education, students may be in hallways, locker rooms, gymnasiums or other locations that often lack immediate supervision. In these cases, staff and students should be trained to move quickly to the nearest secured room or designated shelter location.

Live video feeds and sensors can help security teams and law enforcement identify areas where students may be exposed. Automated lockdown systems can restrict access to hallways and help isolate threats. Schools should also consider the layout of their facilities when planning responses to lockdown in schools, particularly for large campuses with multiple buildings.

During transportation and arrival or dismissal

Although less frequent, lockdowns in school settings can happen during arrival or dismissal. Buses may be in motion, parents may be on campus and students could be arriving at or leaving the building. In these scenarios, coordination between transportation teams, school staff and law enforcement is key.

Access control can help secure entrances and notify offsite staff about the lockdown status. School lockdown procedures should include steps for bus drivers to take, such as pulling over to a secure location and waiting for guidance.

Visitor and vendor protocols

Schools must also plan for lockdown procedures involving non-residents, such as vendors, substitute teachers and parents. When a school on lockdown restricts access, these individuals must know where to go and what to do.

Visitor management systems integrated with access control can help schools track and communicate with every person on campus. Lockdown drills at school should include briefings for frequent visitors or contractors so they understand what to do during a lockdown. Communication tools, such as intercoms and secure mobile alerts, can direct visitors to safety even if they’re unfamiliar with the building layout.

Best practices for effective school lockdown drills

To ensure consistency and readiness, school lockdown drills should follow clear, well-documented procedures. Each drill must be taken seriously, with staff and students fully participating as though it were a real emergency.

Below are the core elements that contribute to effective, reliable lockdown drills in schools:

1. Conduct drills frequently

Regular lockdown drills help embed response behaviors into muscle memory for both students and staff. The more frequently lockdown drills are conducted at school, the more likely individuals are to react calmly and appropriately in an actual emergency. Some states mandate a minimum number of drills per year, but many schools go beyond the requirement to ensure preparedness.

Frequent drills also give school security teams opportunities to test building security systems, such as access control features, lockdown buttons and intercom alerts, ensuring they function correctly and integrate seamlessly with other security solutions.

2. Emphasize the importance

Effective school lockdown procedures begin with clear communication about the importance of drills. Teachers and administrators should explain the purpose of each drill and reinforce how it contributes to a safer environment. When students understand that drills are not just a formality but a critical safety measure, they are more likely to participate seriously.

Building security technologies, such as notification systems and video security, should be integrated into training so that users understand their function and benefits during an emergency.

3. Simulate real-world conditions

Each school lockdown drill should simulate a real emergency scenario. That includes practicing during different times of day, involving all school zones and using real signals and alerts. Lights should be turned off, school door lock systems tested and communication protocols followed exactly as they would be during a true lockdown.

Using the school’s security alarm systems and other school security tools during drills helps ensure that all systems are functioning as expected. It also familiarizes staff with tools they’ll rely on under pressure, such as camera feeds, mobile alerts and access control dashboards.

4. Review and refine after each drill

After every drill, security teams and administrators should hold a debriefing to identify areas for improvement. Were all doors secured quickly? Did staff know where to direct students? Did communications reach all parties, including those in less structured areas like gymnasiums or cafeterias?

Insights gathered from drills can guide updates to the school’s EOP and inform future training. School security systems should also be evaluated post-drill to ensure they support the intended outcome.

Enhance school lockdowns with modern security technology

Modern security technology plays a vital role in how schools manage emergencies. Whether during a real incident or a lockdown drill at school, tools like video security, access control and mass notifications help staff respond quickly and confidently. 

These systems provide real-time visibility, automate critical actions and support faster communication, reducing confusion and delays. By integrating these technologies into daily operations and drills, schools can improve safety, coordination and preparedness across the entire campus.

Real-time visibility through video security

AI-powered school security cameras provide instant insight into what’s happening across campus. During a school lockdown, live camera feeds help security teams identify threats, observe movement and guide response teams, all without losing precious time.

Remote door control for faster containment

Advanced access control technology allows schools to lock down buildings or specific areas remotely. This is essential during a hard lockdown, where movement is restricted. In contrast, a soft lockdown may involve securing exterior doors while internal activity continues. Knowing how to shift between the two ensures the right level of response.

Instant alerts and mass notifications

During a school lockdown drill or actual event, mass notification systems deliver real-time updates to staff, students and responders. Automated alerts reduce confusion and ensure that procedures are followed, regardless of the campus size.

Supporting drills and preparedness

School safety technology is most effective when paired with regular training. Schools that routinely conduct lockdown drills reinforce proper procedures and ensure that their systems perform as expected. Practicing responses to both soft lockdowns and hard lockdowns helps everyone stay calm and act quickly.

A safer, more coordinated response

By integrating video security, access control and emergency alert systems, schools can respond to lockdowns more efficiently. These tools, combined with well-planned drills, form a complete approach to school safety to ensure staff and students are prepared, protected and supported in any situation.
