Most schools have established fire evacuation procedures. Staff understand the alarm signal, pupils know where to assemble and regular drills help ensure arrangements remain familiar and effective.

Lockdown procedures can be very different.

While many schools have developed lockdown and invacuation plans, they are often exercised less frequently than fire procedures and can be far more difficult to implement during a real incident.

As schools continue reviewing their safeguarding, security and emergency preparedness arrangements, particularly in response to the forthcoming implementation of Martyn’s Law: The Terrorism (Protection of Premises) Act 2025, one important question remains:

Would your school’s lockdown procedure work in practice if it were needed tomorrow?

In this article, we look at some of the most common weaknesses we encounter when discussing lockdown preparedness with schools, academy trusts, site teams and senior leadership teams.

What Is a School Lockdown Procedure?

A school lockdown procedure is a planned response to a serious incident where people need to remain secured within buildings or designated areas to reduce the risk of harm.

Depending on the nature of the incident, a lockdown may involve:

• Securing external access points
• Restricting movement around the site
• Communicating instructions to staff, pupils and visitors
• Managing access to designated safe locations
• Supporting emergency services during the response

Examples of situations that may require a lockdown include:

• An intruder on site
• Violent or threatening behaviour
• A serious safeguarding concern
• Police activity close to the school
• A terrorism-related incident

What Is the Difference Between a Lockdown and an Invacuation?

Evacuation

Evacuation involves moving people away from danger by leaving the building.

Invacuation

Invacuation involves bringing people from external areas into the relative safety of a building.

Lockdown

Lockdown involves securing the site and restricting movement to protect people from a threat.

In practice, an incident may involve a combination of these responses depending on the circumstances and location of the threat.

Why Are Schools Reviewing Lockdown Procedures?

Martyn’s Law has increased awareness of preparedness planning across publicly accessible premises, including schools.

However, effective lockdown planning should not be viewed solely through the lens of compliance.

Department for Education guidance encourages schools to consider security as part of their wider safeguarding, health and safety and emergency preparedness arrangements.

For many schools, the key objective is not simply to have a documented procedure. It is to ensure staff, pupils, visitors and contractors understand what to do should an incident occur.

Lockdown Planning Should Support Wider Safeguarding Arrangements

School lockdown procedures are often discussed as a security issue. In practice, they should also be viewed through the wider safeguarding responsibilities of the school.

Keeping Children Safe in Education (KCSIE) 2026 places significant emphasis on safeguarding policies, staff training, information sharing and a whole-school approach to protecting children.

Whilst the guidance does not prescribe a specific lockdown procedure, it reinforces the principle that schools should have effective arrangements in place to help protect pupils and support staff in responding to incidents that may place children at risk.

For this reason, we encourage schools to view lockdown planning as a safeguarding exercise supported by security measures rather than a security project supported by safeguarding.

An Observation From School Security Reviews

One observation we have consistently made when discussing preparedness with schools is that fire evacuation procedures are generally more mature than lockdown procedures.

This is understandable.

Fire drills have been part of school life for many years. Lockdown and invacuation planning has received significantly more attention in recent years and many schools are still developing their approach.

In most cases, the schools we meet have already invested considerable thought into safeguarding and emergency planning.

However, the difference between a documented procedure and genuine operational preparedness often only becomes clear when practical questions are asked and assumptions begin to be challenged.

What Should a School Lockdown Procedure Include?

Every school is different, however most lockdown procedures should consider:

• How a lockdown is initiated
• Who has authority to declare a lockdown
• How messages are communicated across the site
• Classroom responsibilities
• Reception responsibilities
• Visitor and contractor management
• Site security arrangements
• Emergency service liaison
• The all-clear process
• Post-incident welfare and recovery

The most effective procedures are usually those that reflect how the school actually operates rather than relying on generic templates.

7 Common Weaknesses We See in School Lockdown Procedures

1. Everyone Knows What Happens During a Lockdown, But Not How One Starts

This is one of the most common observations we make.

During a fire emergency the process is normally straightforward. Anyone discovering a fire can operate the nearest manual call point and immediately raise the alarm.

Lockdown procedures are often less clear.

Consider a classroom teacher who witnesses a serious incident.

How is the lockdown initiated?

Who do they contact?

What happens if reception cannot be reached immediately?

We often find schools have considered what happens once lockdown has been declared but have spent less time considering how lockdown is actually initiated in the first place.

2. Reception Teams Are Often Overlooked

Many lockdown discussions quite rightly focus on pupils and teaching staff.

However, reception teams are often the people closest to the incident and may be responsible for:

• Managing visitors
• Initiating communications
• Contacting emergency services
• Controlling access points
• Coordinating information

Despite this, reception staff are frequently located outside the secure access-controlled area and may only be protected by a low counter.

Another question schools should consider is where reception staff go once a lockdown has been initiated.

In many schools, significant thought has gone into protecting classrooms whilst reception arrangements have received less attention.

3. Visitors and Contractors Don’t Know What To Do

Most schools put considerable effort into staff awareness.

Visitors and contractors are often a different story.

If a lockdown occurred right now:

• Would they recognise the signal?
• Would they understand what it means?
• Would they know where to go?
• Would they know who to follow?

These questions are rarely asked until a procedure is reviewed in detail.

4. Communication Is Assumed To Work

Communication failures can quickly undermine even the best-written procedure.

We frequently see schools where communication arrangements work well inside the main building but become less effective in:

• Sports facilities
• Playgrounds
• Modular classrooms
• Temporary buildings
• Detached teaching blocks

The question should not be whether a message can be sent.

The question should be whether every person who needs to receive that information can receive it quickly, clearly and consistently.

5. Technology Is Considered Before Procedures

One of the most common reasons schools contact us is because a decision has already been made to purchase technology.

Sometimes this is because a system has been seen elsewhere.

Sometimes it is because there is an assumption that existing systems will not support the school’s procedures.

While technology may ultimately form part of the solution, we generally believe it should not be the starting point.

The better approach is to first understand:

• The procedure
• The responsibilities
• The communication requirements
• The current systems already in place

Only then can meaningful gaps be identified.

In some cases this may result in investment in technology. In others, the solution may be procedural, operational or training related.

6. Procedures Have Never Been Stress Tested

One method we frequently use whilst reviewing procedures is introducing realistic “what if” scenarios.

Not because they are likely.

Because this is where weaknesses are often discovered.

Examples might include:

• The safeguarding lead is absent
• The incident occurs during lunch
• The threat originates inside the building
• Reception cannot be contacted
• The first witness is working in a detached block

A common response is:

“That is unlikely. We would deal with it if it happened.”

But this is precisely why emergency planning exists.

The more thought that can be applied beforehand, the more prepared staff are likely to be when faced with uncertainty.

7. The Procedure Exists But Nobody Practises It

A well-written procedure is an important starting point.

However, documentation alone does not create preparedness.

In our experience, the schools that appear best prepared are often not the schools with the largest policies.

They are the schools that regularly challenge, discuss and exercise their procedures.

The larger the organisation, the more opportunities there are for communication failures, misunderstandings and unexpected issues.

Practice helps ensure everyone understands their role and improves confidence when decisions need to be made quickly.

How Do You Know If A School Is Really Prepared?

Over the years, we have attended countless meetings involving safeguarding leads, facilities managers, business managers, IT teams and members of the senior leadership team.

Those meetings are important and often demonstrate that considerable planning has already taken place.

However, one of the questions we often ask before leaving is directed at somebody else entirely.

The receptionist.

The question is simple:

“If there was a lockdown this afternoon, what would you do?”

The answer is often revealing.

In schools where preparedness is genuinely embedded, the response is usually immediate and confident.

The receptionist understands the procedure, knows what communication to expect, understands their responsibilities and can explain what happens next.

That confidence rarely comes from a document alone.

It comes from communication, training, discussion and practice.

School Lockdown Procedure Checklist

• Do we have documented lockdown and invacuation procedures?
• Is it clear how a lockdown is initiated?
• Do staff understand their responsibilities?
• Can communication reach all occupied areas?
• Have visitors and contractors been considered?
• Do reception staff have a defined role?
• Have arrangements been reviewed following building changes?
• Have procedures been exercised or tested?
• Do current systems support the agreed procedure?
• Can staff confidently explain what they would do during an incident?

Frequently Asked Questions

Does Martyn’s Law apply to schools?

Schools may fall within the scope of the legislation depending on their circumstances. Educational settings benefit from specific provisions under the legislation and remain within the Standard Tier even where large numbers of people may be present.

Does Martyn’s Law require access control systems?

No. The legislation does not mandate specific security technologies. Schools should consider measures that are appropriate and proportionate to their circumstances.

Should schools practise lockdown procedures?

Procedures are generally more effective when staff understand their responsibilities and have had opportunities to discuss, review and exercise the arrangements.

How often should lockdown procedures be reviewed?

Procedures should be reviewed periodically and following significant changes to the building, staffing structures, communications systems or site operations.

Need a School Lockdown Preparedness Review?

At i Security, we help schools and academy trusts review lockdown procedures, emergency communications, visitor management, access control arrangements and wider site security measures.

Our approach starts with understanding how the school operates, how incidents would be managed and whether existing procedures, people and systems would work together effectively.

Only once operational requirements are understood can informed decisions be made about whether changes to processes, staff training, communication arrangements or technology are genuinely required.

In our experience, the most valuable reviews do not always result in major capital expenditure. Often they identify practical procedural improvements that strengthen preparedness whilst supporting the school’s wider safeguarding responsibilities.

Final Thoughts

The objective should not be to purchase technology.

The objective should be to understand whether people, procedures and systems work together effectively.

In some schools, that review may identify a need for additional technology.

In others, the most valuable improvements may be procedural changes, clearer responsibilities, improved communication or a greater emphasis on exercising existing plans.

Ultimately, effective preparedness is not measured by the size of a policy document.

It is measured by whether people understand what to do when it matters most.

In our experience, one of the simplest tests of preparedness is asking a receptionist what they would do if a lockdown was declared this afternoon. The schools that answer confidently are rarely relying solely on documentation. They have discussed, practised and embedded the procedure throughout the organisation.
