  1. What is the main purpose of a security officer's role at a site?

    • ATo protect people, property and premises from loss, harm and disorder✓
    • BTo investigate crimes and then prosecute offenders through the courts
    • CTo take over policing duties so that officers are no longer needed
    • DTo issue legally binding penalty fines to members of the public

    Answer: The core purpose of private security is to protect people, property and premises by deterring, detecting and responding to threats such as crime and disorder. Security officers do not prosecute offenders or take over policing functions.

  2. Which of the following best describes a routine responsibility of a security officer?

    • ASentencing offenders to the appropriate punishment for their crimes in court
    • BGranting official police bail to people who are suspected of committing offences, then releasing them
    • CObserving, reporting and recording incidents accurately while on duty✓
    • DAuthorising covert surveillance operations against named suspects on the site

    Answer: Observing, accurately recording and reporting incidents is a central day-to-day responsibility of a security officer. Sentencing, granting bail and authorising covert operations are functions of the courts or the police, not security staff.

  3. How do the legal powers of a security officer compare with those of a police constable?

    • AA security officer has the same powers of arrest and search as a constable
    • BA security officer may detain anyone they wish until the police arrive
    • CA security officer has no more legal powers than any other member of the public✓
    • DA security officer can use any level of force because they hold an SIA licence

    Answer: A security officer holds no special legal powers and has the same legal standing as any other member of the public. They rely on powers available to everyone, such as the "any person" arrest power, rather than police powers.

  4. Which behaviour best demonstrates professionalism in a security officer?

    • ARemaining calm, polite and impartial when dealing with the public✓
    • BSharing CCTV images of incidents on personal social media accounts
    • CAccepting small gifts from visitors in return for ignoring the rules
    • DGuessing at the answer when a member of the public asks for help

    Answer: Professionalism means staying calm, polite, honest and impartial when dealing with members of the public. Sharing images, accepting gifts to ignore rules, or giving inaccurate information all breach professional standards.

  5. How can a security officer best contribute to community safety initiatives?

    • ABy carrying out independent armed patrols of the surrounding public streets
    • BBy keeping all observations private and never passing them to any other body
    • CBy sharing relevant information and co-operating with the police and partners✓
    • DBy stopping and detaining local people who happen to look suspicious

    Answer: Security officers support community safety by co-operating with the police and local partnerships and sharing relevant information appropriately. They do not carry weapons, withhold useful information, or detain people merely for looking suspicious.

  6. What is the Approved Contractor Scheme (ACS) operated by the SIA?

    • AA compulsory licence that individual security officers hold to work on site
    • BA government insurance policy that pays out when a guarding company fails
    • CA voluntary scheme that assesses security suppliers against agreed standards✓
    • DA register of convicted offenders that security companies screen staff against

    Answer: The Approved Contractor Scheme is a voluntary scheme through which the SIA assesses security businesses against a set of agreed quality standards. It applies to organisations that supply security services, not to individual licence holders.

  7. Which statement about an SIA Approved Contractor is correct?

    • AIts individual officers no longer need to hold their own SIA licences
    • BIt has shown that it meets the quality standards set for the scheme✓
    • CIt is a public body with statutory powers to inspect rival companies
    • DIt is guaranteed all public-sector security contracts within its region

    Answer: Becoming an Approved Contractor shows that a supplier has demonstrated it meets the scheme's quality standards. Approval does not remove the need for individual staff to be licensed, nor does it grant statutory powers or guaranteed contracts.

  8. What is the Security Industry Authority (SIA)?

    • AA trade union that negotiates pay and conditions for security staff
    • BA private insurer that covers security firms against all legal claims
    • CA charity that offers free legal representation to security officers
    • DThe body responsible for regulating the UK private security industry✓

    Answer: The Security Industry Authority is the organisation responsible for regulating the private security industry across the UK. It was established under the Private Security Industry Act 2001 and reports to the Home Office.

  9. Which piece of legislation established the Security Industry Authority?

    • AThe Criminal Law Act 1967
    • BThe Police and Criminal Evidence Act 1984
    • CThe Private Security Industry Act 2001✓
    • DThe Data Protection Act 2018

    Answer: The Private Security Industry Act 2001 created the Security Industry Authority and introduced compulsory licensing of the industry. The other statutes deal with the use of force, police powers and data protection respectively.

  10. Which activity requires an SIA licence when it is carried out under contract?

    • AServing food and drink to customers inside a licensed venue
    • BCleaning offices and communal areas outside of normal working hours
    • CGuarding premises and property against theft or unauthorised access✓
    • DSelling retail goods from a fixed counter inside a shopping centre

    Answer: Guarding premises, property or people against threats such as theft is a licensable security activity under the Private Security Industry Act 2001. Catering, cleaning and retail sales are not licensable activities.

  11. What is the difference between a front-line and a non-front-line SIA licence?

    • AA front-line licence lasts one year while a non-front-line licence lasts five
    • BA front-line licence is for staff carrying out the licensable activity itself✓
    • CA front-line licence is only needed by managers who never leave the office
    • DA front-line licence allows the holder to carry and use defensive weapons

    Answer: A front-line licence is required by those who actually carry out a licensable activity, while a non-front-line licence covers those who manage or employ but do not do the activity themselves. A front-line licence is issued as a photographic card and does not permit carrying weapons.

  12. How long is a front-line SIA security guard licence normally valid for?

    • AThree years from the date that it is first issued to the holder✓
    • BOne year from the date that it is first issued to the holder
    • CFive years from the date that it is first issued to the holder
    • DIt never expires once it has first been issued to the holder

    Answer: A front-line SIA security guard licence is normally valid for three years. The holder must apply to renew it before it expires in order to keep working lawfully.

  13. How should a security officer display their front-line SIA licence while on duty?

    • ALocked inside the site office, out of sight, so that it cannot be lost
    • BKept at home and only produced if a police officer asks to inspect it
    • CWorn so that the front of the licence can be seen at all times✓
    • DPhotographed and stored on a personal phone instead of the physical card

    Answer: SIA licence conditions say a front-line licence must be worn where the front can be seen at all times during licensable work. Covert roles, such as store detectives, are the exception, but they must still carry it and produce it on request.

  14. What is the consequence of carrying out licensable security work without an SIA licence?

    • AA written warning is issued but the work may then lawfully continue
    • BThe SIA simply adds the person to a waiting list for a future licence
    • CThere is no consequence provided that an employer agreed to the arrangement
    • DIt is a criminal offence that can lead to a fine and/or imprisonment✓

    Answer: Working in a licensable role without the required SIA licence is a criminal offence that can result in a fine and/or imprisonment. An employer's agreement does not make unlicensed work lawful.

  15. A supervisor manages licensed officers but never carries out the guarding duties personally. Which statement is correct?

    • AThe supervisor is exempt, since licensing applies to front-line staff
    • BThe supervisor needs a front-line licence and has to wear it while on site
    • CThe supervisor may need a non-front-line licence for the managing role✓
    • DThe supervisor automatically holds a licence because the staff are licensed

    Answer: Someone who manages, supervises or employs licensable staff without doing the activity themselves may require a non-front-line licence. This is separate from the front-line licence held by the officers carrying out the guarding.

  16. Which of the following is dealt with mainly under criminal law rather than civil law?

    • AA dispute between two neighbours about the position of a shared boundary fence
    • BA civil disagreement over the terms of a signed commercial contract between two firms
    • CThe theft of goods from a shop by a person who intends to keep them✓
    • DA claim for compensation following a minor road traffic collision in a car park

    Answer: Theft is a criminal offence and is dealt with under criminal law, which concerns wrongs against society and is prosecuted by the state. Boundary disputes, contract disagreements and compensation claims are civil matters between parties.

  17. What is the standard of proof required to convict someone in a criminal case?

    • AThe case must be proved on the balance of probabilities
    • BThe accused must prove that they are completely innocent
    • CThe case must be proved beyond reasonable doubt✓
    • DA simple majority of the witnesses must support the allegation

    Answer: In a criminal case the prosecution must prove the defendant's guilt beyond reasonable doubt. This is a higher standard than the "balance of probabilities" test used in civil cases.

  18. A member of the public refuses to leave private premises after being asked. In general, what kind of matter is simple trespass?

    • AUsually a civil matter rather than a criminal offence in itself✓
    • BAn indictable offence for which a security officer can make an arrest
    • CAn offence for which security officers can personally issue a fixed fine
    • DA matter that is referred directly to the local council to resolve

    Answer: Simple trespass on land is generally a civil matter rather than a criminal offence. Security officers can ask a trespasser to leave, but trespass alone does not usually give rise to a power of arrest.

  19. In the context of reporting an incident, which of the following is an example of real (physical) evidence?

    • AA rumour passed on by someone who did not actually see the incident
    • BA security officer's personal opinion about who was really to blame
    • CA guess about what probably happened based on past experience
    • DA weapon or stolen item recovered from the scene of the incident✓

    Answer: Real or physical evidence is a tangible item connected to an incident, such as a recovered weapon or item of stolen property. Rumours, opinions and guesses are not reliable forms of evidence.

  20. Why should a security officer carefully record who has handled a recovered item?

    • ABecause the item automatically becomes the officer's personal property
    • BBecause maintaining continuity helps preserve the integrity of the evidence✓
    • CBecause only handwritten notes in ink are accepted as evidence in court
    • DBecause it allows the officer to decide the suspect's guilt themselves

    Answer: Keeping a clear record of who has handled an item maintains continuity, or chain of custody, which helps preserve the integrity of the evidence. This supports the reliability of the evidence if the matter later goes to court.

  21. The "any person" power of arrest that a security officer may rely on is found in which statute?

    • AThe Criminal Law Act 1967, which deals with the use of force
    • BThe Police and Criminal Evidence Act 1984, at section 24A✓
    • CThe Equality Act 2010, which lists the protected characteristics
    • DThe Human Rights Act 1998, which sets out fundamental rights

    Answer: The "any person" power of arrest is set out in section 24A of the Police and Criminal Evidence Act 1984. It allows a person who is not a constable to make an arrest in limited, defined circumstances.

  22. The "any person" arrest power under section 24A can generally be used only in relation to which type of offence?

    • AA summary offence, such as being drunk and disorderly in a public place
    • BA purely civil wrong, such as breaking the agreed terms of a commercial contract
    • CAn indictable offence, which includes either-way offences such as theft✓
    • DA breach of the site's rules, such as smoking in a no-smoking area

    Answer: The 'any person' arrest power in section 24A of PACE 1984 covers indictable offences, which include all either-way offences such as theft. It does not cover summary-only offences or civil matters, and the other conditions in section 24A must also be met, such as it not being practicable for a constable to make the arrest.

  23. Under section 24A, as well as an indictable offence being involved, what else must be true before a security officer makes an arrest?

    • AA police officer has already given written permission for the arrest to go ahead
    • BThe suspect has already signed a written form agreeing to be detained on the site
    • CIt is not reasonably practicable for a constable to make the arrest instead✓
    • DThe officer intends to question the suspect fully before any police attend

    Answer: Section 24A allows a citizen's arrest only where it is not reasonably practicable for a constable to make it instead, and the arrest is necessary for a reason such as preventing injury or the suspect making off. It does not require written police permission or a signed agreement, and a security officer should not detain someone simply to interrogate them.

  24. When can the "any person" arrest power under section 24A lawfully be exercised?

    • ABefore an offence has taken place, where the officer suspects one is planned
    • BWhen a summary offence is being committed, or after one has been committed
    • CWhile an indictable offence is being committed, or after one has been committed✓
    • DWhen the site manager instructs the officer to detain a suspect

    Answer: The "any person" power can be used while an indictable offence is being committed, or where one has been committed and a person is reasonably suspected of being guilty. It cannot be used in anticipation of an offence that has not yet occurred.

  25. Section 3 of the Criminal Law Act 1967 allows a person to use what in the prevention of crime?

    • AWhatever level of force the person personally feels like using
    • BForce only in the event that they are a serving police constable
    • CUnlimited force for as long as a crime has actually taken place
    • DSuch force as is reasonable in the circumstances that are faced✓

    Answer: Section 3 of the Criminal Law Act 1967 permits a person to use such force as is reasonable in the circumstances in the prevention of crime or in making a lawful arrest. The force used must always be reasonable and proportionate.

  26. Which principle must always apply when force is used to prevent crime or to make an arrest?

    • AThe force can be as severe as the officer wishes once a crime occurs
    • BThe force should continue until the suspect admits that they were guilty
    • CThe force must be reasonable and proportionate to the circumstances✓
    • DThe force may be used freely to punish the suspect for their actions

    Answer: Any force used must be reasonable and proportionate to the circumstances faced at the time. Force must never be used as a punishment, and it should stop once it is no longer necessary.

  27. Which situation best describes the criminal offence of theft?

    • AAccidentally walking out of a shop still holding an item by mistake
    • BDishonestly taking another person's property intending to keep it✓
    • CBorrowing a colleague's pen and then returning it a few minutes later
    • DBeing given too much change at the till and noticing only later

    Answer: Theft involves dishonestly appropriating property belonging to another with the intention of permanently depriving them of it. Genuine accidents and temporary borrowing with the intention to return do not meet this definition.

  28. In law, which of the following best describes a common assault?

    • ADeliberately and permanently damaging another person's physical property
    • BCausing another person to fear immediate unlawful violence against them✓
    • CDishonestly taking goods from a shop without paying for them at all
    • DEntering onto private land without first getting the occupier's permission to do so

    Answer: A common assault is committed when a person causes another to fear immediate unlawful violence. Damaging property, taking goods dishonestly and entering land without permission are different matters, namely criminal damage, theft and trespass.

  29. A person deliberately smashes a window belonging to someone else without any lawful excuse. Which offence is this most likely to be?

    • ACriminal damage to property belonging to another person✓
    • BCommon assault committed against another individual person
    • CHandling goods that are known to have been stolen from a shop
    • DBribery intended to influence another person's conduct

    Answer: Intentionally destroying or damaging property belonging to another without lawful excuse is the offence of criminal damage. It is distinct from assault, handling stolen goods or bribery, which all involve different conduct.

  30. Which of the following is a protected characteristic under the Equality Act 2010?

    • AA person's age, race, sex, religion or disability✓
    • BThe type of car that a person chooses to drive
    • CThe football team that a person happens to support
    • DThe amount of money that a person earns each month

    Answer: The Equality Act 2010 protects characteristics including age, disability, race, religion or belief, sex and sexual orientation, among others. Preferences such as the car someone drives or the team they support are not protected characteristics.

  31. What is meant by indirect discrimination under the Equality Act 2010?

    • ATreating a person less favourably directly because of their race, sex or another characteristic
    • BA rule that applies to everyone but unfairly disadvantages a protected group✓
    • COffering extra help to a disabled person so that they can use a service more easily
    • DRefusing point blank to serve a named individual that the staff happen to dislike

    Answer: Indirect discrimination occurs when a provision, criterion or practice applies to everyone but puts people who share a protected characteristic at a particular disadvantage without justification. Treating someone less favourably directly because of a characteristic is direct discrimination.

  32. A wheelchair user asks a security officer for directions to an accessible entrance. What is the appropriate response?

    • ARefuse to help because assisting visitors is not really a security duty
    • BDirect them to the nearest stairs and tell them to manage as best they can
    • CAsk them to prove their disability before giving any assistance at all
    • DPolitely help them find the accessible route, treating them with respect✓

    Answer: Security officers should treat all members of the public fairly and with respect, which includes helping a disabled visitor find an accessible route. Refusing help or demanding proof of disability could amount to discrimination under the Equality Act 2010.

  33. Under data protection law, how should CCTV footage of identifiable people be treated?

    • AAs public property that anyone at all may copy and share on request
    • BAs personal data that must be handled lawfully, fairly and securely✓
    • CAs material that can be kept forever with no need for any policy
    • DAs images that the operator may freely sell to any interested party

    Answer: CCTV footage of identifiable individuals is personal data and must be handled lawfully, fairly and securely under the Data Protection Act 2018 and UK GDPR. It cannot be kept indefinitely without reason, shared freely or sold on.

  34. Which practice is consistent with the data protection principles when operating CCTV?

    • ARecording in private changing rooms, to deter thefts from lockers
    • BKeeping recordings for years in case they prove useful later
    • CLetting staff view the recordings whenever they feel curious
    • DUsing clear signage so people know that CCTV is in operation on site✓

    Answer: Informing people through clear signage that CCTV is in operation supports the requirement for fair and transparent processing. Excessive monitoring, indefinite retention and uncontrolled access all breach data protection principles.

  35. What does the Human Rights Act 1998 do?

    • AIt gives security officers the same arrest powers as the police have
    • BIt gives effect in UK law to fundamental rights and freedoms✓
    • CIt allows employers to ignore the privacy of their own members of staff
    • DIt makes all forms of simple trespass an arrestable criminal offence

    Answer: The Human Rights Act 1998 gives effect in UK law to fundamental rights and freedoms, such as the right to liberty and respect for private life. Security officers should carry out their duties in a way that respects these rights.

  36. A visitor offers a security officer cash to "look the other way" while goods are removed. What should the officer do?

    • AAccept the cash quietly as long as no one else happens to see it
    • BTake the money, agree to it, and then keep the goods for themselves
    • CRefuse the money and report the attempted bribe to their manager✓
    • DNegotiate a higher amount before deciding whether to allow it

    Answer: Offering or accepting a bribe is a criminal offence, so the officer should refuse and report the attempt to their manager. Accepting money to ignore theft could also make the officer complicit in offences such as theft or handling stolen goods.

  37. What distinguishes the offence of robbery from ordinary theft?

    • ARobbery is theft carried out using force or the threat of force✓
    • BRobbery is theft committed inside a person's private home
    • CRobbery is theft of property worth more than £200
    • DRobbery is theft where the property stolen is cash or a vehicle

    Answer: Robbery is theft that is carried out by using force on a person, or by putting them in fear of force, in order to steal. It does not require a weapon, a particular location or a particular type of property.

  38. Which scenario best describes the offence of burglary?

    • AEntering a building as a trespasser with intent to steal property inside✓
    • BUsing threats of force against a person in order to steal property from them
    • CTaking goods from an open shop shelf and walking out without paying at the till
    • DDeliberately damaging the outside wall of a building after dark

    Answer: Burglary involves entering a building, or part of one, as a trespasser intending to steal, or stealing once inside. Using force to steal from a person is robbery, while simply taking goods without paying is theft.

  39. What is the main difference between common assault and assault occasioning actual bodily harm (ABH)?

    • AABH involves the attacker holding a weapon, beyond a common assault
    • BABH involves actual injury to the victim, beyond a common assault✓
    • CABH is a purely civil matter, whereas common assault is a criminal offence
    • DABH applies to an assault against emergency workers who are on duty

    Answer: Actual bodily harm involves some real injury or hurt to the victim, which makes it more serious than common assault. Common assault covers causing someone to fear violence, or minor contact that causes no real injury.

  40. An officer holds a person against their will without any lawful reason to do so. This is most likely to amount to which wrong?

    • ACriminal damage to various items of property belonging to the detained person
    • BHandling stolen goods that were taken from the detained person
    • CA simple breach of the officer's own contract of employment
    • DFalse imprisonment, because the person's liberty is unlawfully restricted✓

    Answer: Detaining someone without lawful justification, so that they are not free to leave, can amount to false imprisonment. This is why an officer must be certain that a detention is lawful before restricting anyone's liberty.
