What is the difference between reasonable force and excessive force?

Reasonable force is that which is necessary and proportionate in the circumstances as the officer honestly believed them to be. Excessive force goes beyond what is needed, often due to anger, panic, or poor judgment. The test is objective: would a reasonable person in the same situation have used the same level of force? If not, it may be excessive and could lead to criminal or disciplinary action.

How does the Human Rights Act affect use of force by police?

The Human Rights Act 1998 incorporates the European Convention on Human Rights into UK law. Article 2 (right to life) requires that any use of lethal force must be absolutely necessary. Article 3 prohibits torture or inhuman treatment, meaning force must never be degrading. Article 8 (right to private life) requires that any interference (e.g., physical restraint) must be lawful and proportionate. These articles set a high bar for justifying force.

Can I use force to prevent a crime if I am off-duty?

Yes, under the Criminal Law Act 1967, s.3, any person may use reasonable force to prevent crime or effect a lawful arrest. However, off-duty officers must consider their training, the risk to themselves and others, and whether intervention is necessary. The same legal tests apply, but the context (e.g., lack of equipment, backup) may affect what is considered reasonable.

What is the National Decision Model and why is it important?

The National Decision Model (NDM) is a framework used by UK police to make and record decisions, especially in use of force situations. It has six stages: Information, Threat Assessment, Powers and Policy, Options, Action, and Review. It is important because it ensures decisions are structured, defensible, and transparent, helping officers justify their actions in court or at inquest.

Do I have to follow the use of force continuum exactly?

No, the use of force continuum is a training tool, not a legal requirement. It illustrates possible levels of force (e.g., presence, verbal, empty hand, intermediate weapons, lethal) but officers can escalate or de-escalate as the situation demands. The key is that the force used must be reasonable and proportionate, not that it follows a specific order.

What happens if I use force that is later deemed excessive?

If force is found to be excessive, you may face criminal charges (e.g., assault, manslaughter), civil claims for damages, and disciplinary action including dismissal. Your employer may also be liable. However, the law considers the circumstances at the time, including the stress and fast-moving nature of incidents. Honest mistakes may be treated more leniently than deliberate abuse.

BAA Level 4 Certificate in Use of Force Instruction

Topic Overview

The BAA Level 4 Certificate in Use of Force Instruction is a specialist qualification for those who train others in the lawful and proportionate application of force within public services, such as the police, security, and custodial settings. This unit covers the legal, ethical, and practical frameworks that govern the use of force, ensuring instructors can deliver safe, effective, and legally compliant training. It is a critical component of the Public Services curriculum because it directly addresses the balance between individual rights and public safety, a core tension in modern policing and security roles.

Students will explore key legislation including the Criminal Law Act 1967, the Police and Criminal Evidence Act 1984 (PACE), and the Human Rights Act 1998, focusing on how these laws define reasonable force. The course also delves into risk assessment, dynamic risk management, and the National Decision Model (NDM), which guides practitioners in making defensible decisions under pressure. By mastering these concepts, learners develop the expertise to design and deliver use of force training that meets national standards and reduces liability for their organisations.

This qualification sits within the broader Public Services framework as a specialised elective, building on foundational knowledge of criminal justice and public protection. It is particularly relevant for those aspiring to roles as police trainers, security managers, or custody officers, where the ability to instruct others in use of force is essential. The course emphasises not just technical skill but also the ethical reasoning and accountability required to justify force in a democratic society.

Key Concepts

Core ideas you must understand for this topic

→Reasonable Force: The legal principle that force must be necessary, proportionate, and reasonable in the circumstances as the officer believed them to be. This is assessed objectively by a court, considering the threat perceived at the time.
→National Decision Model (NDM): A structured framework for decision-making in policing that includes information, threat assessment, powers and policy, options, and action. It ensures decisions are recorded and defensible.
→Dynamic Risk Assessment: The continuous process of evaluating changing threats and environmental factors during an incident, allowing the officer to adapt their use of force accordingly.
→Use of Force Continuum: A model that illustrates escalating levels of force (from presence to lethal force) and the corresponding officer responses, though it is not a rigid checklist but a guide for decision-making.
→Legal Framework: Key statutes include the Criminal Law Act 1967 (s.3 – reasonable force in crime prevention), PACE 1984 (s.117 – powers of constables to use reasonable force), and the Human Rights Act 1998 (Article 2 – right to life, Article 3 – prohibition of torture, Article 8 – right to private life).

Learning Objectives

What you need to know and understand

Understand and be able to explain and demonstrate the importance of health and safety relating to Use of Force instructors in line with legal and company requirements, Be able to deliver accurate and realistic demonstrations and give learners the opportunity to practice skills being demonstrated, Be able to demonstrate and explain how to use Personal Protective Equipment and other aids correctly and in accordance with organisational procedures and legislative requirements

Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for clearly explaining and consistently applying health and safety measures, including dynamic risk assessments, during the delivery of practical use of force sessions.
Credit should be given for delivering demonstrations that are technically accurate, clearly visible, and accompanied by a step-by-step breakdown that allows learners to practice safely.
Assessors must see evidence of correct selection, fitting, and usage of personal protective equipment, with explanation linking each item to relevant organisational procedures and legislative requirements.

Assessment Guidance

Guidance for achieving higher grades

💡Prioritise safety by beginning every practical session with a thorough briefing referencing legal and company requirements, and document this in your portfolio.
💡Use the 'EDICT' model (Explain, Demonstrate, Imitate, Coach, Test) to structure your teaching, ensuring you can evidence each stage in your assessment.
💡When evidencing PPE use, include photographs or video with voiceover that explicitly states how each item meets legislative and organisational standards.
💡When answering questions on reasonable force, always reference the specific legislation (e.g., Criminal Law Act 1967, s.3) and explain how the 'honestly held belief' of the officer is key. Examiners look for precise legal terminology and application to scenarios.
💡Use the National Decision Model (NDM) as a framework for structuring answers on decision-making. Start with 'Information' and work through each stage, showing how it leads to a justified action. This demonstrates systematic thinking and gets higher marks.
💡For scenario-based questions, explicitly state the threat assessment (e.g., 'the subject was armed with a knife and advancing') and link it to the force option chosen. Avoid vague statements like 'I would use proportionate force' – be specific about the technique and its justification.

Common Mistakes

Common errors to avoid in your coursework

Assuming learners will intuitively understand safety protocols without explicit, repeated instruction and reinforcement before and during practical exercises.
Failing to differentiate between demonstration for skill acquisition and scenario-based realism, leading to confusion or unsafe practice.
Neglecting to monitor and correct PPE usage throughout the session, resulting in learners developing poor habits or becoming injured.
Misconception: 'Reasonable force means you can only use the same level of force as the suspect.' Correction: Reasonable force is judged on necessity and proportionality, not equivalence. An officer may use greater force than the suspect if it is necessary to prevent harm, e.g., using a Taser against an unarmed but aggressive person.
Misconception: 'The use of force continuum is a strict ladder you must follow step-by-step.' Correction: The continuum is a guide, not a legal requirement. Officers can skip levels if the situation demands it, e.g., going directly from presence to lethal force if there is an immediate threat to life.
Misconception: 'If you follow policy, you cannot be prosecuted.' Correction: Following policy does not automatically make force lawful. The law (e.g., Human Rights Act) overrides policy, and each use of force is judged on its own merits. Policy compliance is a factor but not a defence.
