  1. What are assignment instructions?

    • AA site-specific document setting out the duties, procedures and requirements for the post✓
    • BA national code of conduct, published by the SIA, that applies to every licence holder
    • CThe officer's personal contract of employment with the security company
    • DA printed log used to record the arrival and departure of site visitors

    Answer: Assignment instructions are a site-specific document that sets out the duties, procedures and requirements for a particular post or site. Officers should read and follow them, as they cover how that specific location is to be guarded.

  2. Why is it important for a security officer to arrive on time for the start of a shift?

    • AIt allows the incoming officer to skip completing the handover paperwork for that day
    • BIt ensures a proper handover takes place and security cover is not broken✓
    • CIt reduces the total number of patrols that need to be carried out during that day
    • DIt means the control room can switch off the CCTV monitors during the changeover period

    Answer: Arriving on time ensures a proper handover can take place and that security cover at the site is never left broken. Late arrival can leave a post unstaffed and important information unpassed.

  3. At a shift change, what should the outgoing officer do during the handover?

    • ABrief the incoming officer on ongoing incidents, keys and any outstanding tasks✓
    • BLeave the post immediately so the new officer can form their own impressions
    • CTake the occurrence book home to write up the day's events in private
    • DDelete the CCTV recordings made during the shift, to free up storage space

    Answer: At handover the outgoing officer should brief the incoming officer on any ongoing incidents, the keys held and any outstanding tasks. A thorough handover maintains continuity of security between shifts.

  4. A member of the public asks a security officer a question the officer cannot answer. What is the most professional response?

    • ATell the person that answering questions is not part of the security role
    • BGuess at an answer so that the person is not kept waiting at the desk
    • CIgnore the request entirely, and carry on with the current patrol route
    • DPolitely explain that you will find out, and direct them to the right person or information✓

    Answer: The professional approach is to stay helpful, explain that you will find out, and direct the person to the correct source of information. Guessing or dismissing the person damages customer service and the client's reputation.

  5. A security officer's standard of dress and appearance on site matters mainly because it:

    • Aguarantees the officer cannot be identified on the site's CCTV system
    • Bremoves the officer's need to carry or display their own SIA licence card
    • Callows the officer to bypass the site's normal access control points
    • Dprojects authority and professionalism and reassures clients and the public✓

    Answer: A smart, professional appearance projects authority, reassures clients, staff and the public, and reflects well on the employer. It does not replace the legal requirement to hold and be able to produce an SIA licence.

  6. What is a key benefit of varying the times and routes of patrols rather than following a fixed, predictable pattern?

    • AIt allows the officer to avoid patrolling the higher-risk areas of the site
    • BIt reduces the total distance the officer has to walk during a twelve-hour shift
    • CIt makes the officer's movements harder for a would-be intruder to predict✓
    • DIt removes the need to record any of the patrols that are carried out that night

    Answer: Varying patrol times and routes makes an officer's movements unpredictable, so an intruder cannot learn a pattern and time their activity around it. Predictable patrols are much easier to evade.

  7. During an external patrol of a site at night, which of the following should an officer treat as a security concern?

    • AInterior office lights switched off in unoccupied rooms
    • BA perimeter gate found unlocked and standing open✓
    • CStaff vehicles parked in their correctly allocated bays
    • DBins placed at the correct collection point for the morning

    Answer: A perimeter gate found unlocked and open is a security concern, as it is a potential point of unauthorised entry that should be secured and reported. The other observations are normal and expected.

  8. What is the main purpose of the patrol points or recording devices that an officer scans during a round?

    • ATo provide a verifiable record that areas were checked at given times✓
    • BTo automatically lock each door that the officer passes on the route
    • CTo replace the need for the officer to write anything in a notebook
    • DTo measure how many calories the officer burns during the shift

    Answer: Patrol points and clocking devices create a verifiable, time-stamped record showing that areas were actually visited and checked. This confirms patrols took place and supports accountability.

  9. While patrolling, an officer finds cardboard and rubbish stacked against a fire exit door. This is a concern primarily because it:

    • Amakes the corridor look untidy for visitors arriving at reception
    • Bcould obstruct escape and act as a fuel source, creating a fire risk✓
    • Csuggests, quite wrongly, that the cleaning contractor has not been paid on time
    • Dindicates the intruder alarm in that zone has been switched off

    Answer: Combustible material stacked against a fire exit creates a fire risk and can block a vital escape route in an emergency. The officer should have it removed and report the hazard.

  10. A lone officer is about to patrol a remote part of a large site at night. What is the best practice before setting off?

    • ASwitch the radio off so the battery lasts until the end of the twelve-hour shift
    • BProp open the security doors behind them to speed up the return
    • CInform the control room of the route and the expected time to check back in✓
    • DLeave the personal alarm at the gatehouse to avoid triggering it by accident

    Answer: A lone worker should tell the control room their planned route and expected check-in time so that help can be sent if they fail to report back. Keeping the radio and personal alarm with them is also essential.

  11. What best describes the difference between a routine patrol and a random patrol?

    • ARoutine patrols are carried out externally, while random patrols cover the inside of buildings
    • BRoutine patrols are done by two officers, whereas random patrols are done by one officer
    • CRoutine patrols are recorded in the notebook, whereas random patrols are left unrecorded
    • DRoutine patrols follow a set schedule and route; random patrols deliberately vary the timing and route✓

    Answer: A routine patrol follows a set, regular schedule and route, whereas a random patrol deliberately varies its timing and route to be unpredictable. Both types are recorded, and neither is defined by the number of officers.

  12. The main purpose of security patrolling is to:

    • Agive the officer a reason to leave the reception desk unstaffed
    • Bensure that every internal door is left propped open, at all times
    • Callow the officer to collect personal belongings left behind by staff
    • Ddeter, detect and respond to risks such as intrusion, fire and hazards✓

    Answer: Patrolling exists to deter, detect and respond to risks such as intrusion, fire and other hazards around a site. A visible patrolling presence discourages wrongdoing and allows early detection of problems.

  13. When a visitor arrives at a controlled reception, good practice is to:

    • Aallow them straight through so that they are not delayed at the desk
    • Bask them to simply find their own way, unaccompanied, to the person they are meeting
    • Cbook them in, confirm who they are visiting, and issue a visitor pass✓
    • Drecord only their car registration and wave them through the barrier

    Answer: Visitors should be booked in, have the person they are visiting confirmed, and be issued with a visitor pass. This controls who is on site and ensures visitors can be accounted for.

  14. Why should visitors be booked out as well as booked in?

    • ASo the site always knows who remains on the premises, which matters in an evacuation✓
    • BSo that the visitor can be charged a fee based on the length of their stay
    • CSo that the officer has an excuse to keep the visitor waiting at reception
    • DSo that the CCTV system can be switched off, once the last visitor has left

    Answer: Booking visitors out keeps the record of who is on the premises accurate, which is essential for accounting for everyone during a fire or other evacuation. Without it, the site cannot be sure who has left.

  15. A delivery driver arrives at the gate with goods but is not expected and has no paperwork. What should the officer do?

    • ARefuse the delivery and ask the driver to leave the goods outside the gate
    • BWave the delivery straight through to save the driver waiting time
    • CTake the goods in and leave them unattended in the middle of the reception area
    • DCheck the assignment instructions and verify the delivery with the relevant site contact✓

    Answer: An unexpected delivery should be handled by following the assignment instructions and verifying it with the appropriate site contact before accepting it. This prevents unauthorised items or people entering the site.

  16. A person tries to "tailgate" closely behind an employee who has just used their access card at a staff-only door. The officer should:

    • Aassume they are a colleague, because they arrived with a member of staff
    • Bignore it, since tailgating is a concern on the night shift rather than by day
    • Cpolitely stop them, check for a valid pass or ID, and follow the access procedure✓
    • Dreport the employee who used the card for letting the door close too slowly

    Answer: Tailgating should be challenged: the officer should politely stop the person, check for a valid pass or ID, and follow the site's access procedure. Unauthorised people can gain entry if tailgating is ignored.

  17. The primary security reason for controlling both entry to and exit from a building is to:

    • Aensure that the reception area appears busy to visiting clients
    • Ballow the officer to greet each employee personally as they arrive
    • Cmanage who and what enters and leaves, protecting people, property and information✓
    • Dreduce the amount of routine cleaning required in the entrance lobby, daily

    Answer: Access and egress control is about managing who and what enters and leaves, which protects people, property and information. Controlling exit also helps prevent theft and account for everyone on site.

  18. Before searching a person or their bag, a security officer must normally:

    • Aobtain the person's consent to the search✓
    • Bread the person their rights under caution
    • Chandcuff the person for the officer's own safety
    • Dphotograph the contents for the incident report

    Answer: A security officer must normally obtain the person's consent before carrying out a search, as the officer has no special legal power to search. Consent is usually given as a condition of entry.

  19. A visitor refuses to consent to a bag search that is a condition of entry to the site. What is the correct action?

    • ASearch the bag anyway, because the entry conditions override the refusal
    • BDetain the person until they change their mind about the search
    • CConfiscate the bag and allow the person to enter the premises without it
    • DDecline the person entry, as a security officer cannot force a search✓

    Answer: If a person refuses a search that is a condition of entry, the officer can refuse them entry but cannot force the search. A security officer has no power to search a person against their will.

  20. What is good practice when searching a person at a controlled entry point?

    • ACarry out the search out of sight so that nobody can witness it
    • BConduct the search, where possible, by an officer of the same sex and in view of a witness✓
    • CHave the person empty their own pockets, in private, while no one else observes them
    • DSearch only the people the officer personally finds suspicious-looking

    Answer: Good practice is for searches to be carried out, where possible, by an officer of the same sex and in the presence of a witness. This protects both the person being searched and the officer from allegations.

  21. On what basis can a security officer search members of the public entering a venue?

    • AOn powers granted specifically to SIA licence holders by statute
    • BOn the person's consent, usually given as a condition of entry✓
    • COn the same powers of stop and search that a police constable holds
    • DOn the authority of the officer's uniform and SIA licence alone

    Answer: A security officer searches on the basis of the person's consent, which is usually given as a condition of entry to the venue. Officers have no statutory search powers beyond those of any member of the public.

  22. Making a search a published "condition of entry" to a venue is important because it:

    • Ameans visitors who enter have been informed of, and agreed to, the search✓
    • Bgives the officer a legal power to search anyone, even if they refuse
    • Callows the officer to search people without their knowledge or consent
    • Dtransfers responsibility for any prohibited items onto the venue owner

    Answer: Publishing searching as a condition of entry means those who choose to enter have been informed of and consented to being searched. It does not create a power to search anyone who refuses; they can instead be refused entry.

  23. What is the main security purpose of a CCTV system on a site?

    • ATo completely replace the need for any officers to patrol the site in person, day or night
    • BTo record and monitor activity, helping to deter and provide evidence of incidents✓
    • CTo let the officer watch television during quiet periods on the shift
    • DTo control the heating and lighting in the building automatically

    Answer: CCTV monitors and records activity, which helps deter wrongdoing and provides evidence when incidents occur. It supports, but does not replace, officers on the ground.

  24. What does good key control on a site involve?

    • ALeaving keys in the locks of the doors they operate so that they are not mislaid
    • BRecording the issue and return of keys and keeping them stored securely✓
    • CLabelling each key clearly with the full name of the room that it opens
    • DAllowing staff to borrow keys without signing for them in the key log

    Answer: Good key control means recording when keys are issued and returned and keeping them stored securely. Keys should not be openly labelled with the rooms they open, as this helps anyone who steals them.

  25. An intruder alarm activates in a zone of the building during the night. What should the officer do first?

    • ARespond in line with the assignment instructions and investigate the cause safely✓
    • BReset the alarm straight away and assume that it was triggered in error
    • CTelephone the client at home and wait for their instructions
    • DSwitch off the alarm panel so the noise does not disturb the neighbours

    Answer: An alarm activation should be handled by following the assignment instructions and investigating the cause safely. Alarms should never simply be reset or silenced on the assumption that they are false.

  26. Why should spare keys and key cabinets be kept secure and their use logged?

    • ASo that access is controlled and any misuse or loss can be traced✓
    • BSo that lost keys can be replaced by the officer without any authorisation
    • CSo that keys can be taken home by staff for safe-keeping overnight
    • DSo that the locksmith can be charged for cutting any additional copies

    Answer: Securing keys and logging their use keeps control over who can access parts of the site and means any loss or misuse can be traced to a person and time. Uncontrolled keys undermine every lock they fit.

  27. An electronic access control system (such as card or fob readers on doors) offers a security advantage over a simple mechanical lock mainly because it:

    • Astops tailgating, because a door opens for one card holder at a time
    • Blogs who used each door and when, and lets access be withdrawn without changing the lock✓
    • Cremoves the need for the site to employ security officers to check those doors
    • Dmeans the doors no longer need to be closed, or physically checked by anyone on patrols

    Answer: Electronic access control can record who used a door and when, and an individual's access can be withdrawn centrally without replacing the lock. No system, however, makes unauthorised entry completely impossible.

  28. Which set of qualities best describes a good security record or notebook entry?

    • AAccurate, factual, legible and timed✓
    • BBrief, informal, undated and based on opinion
    • CLengthy, decorative, coded and anonymous
    • DVague, optimistic, estimated and unsigned

    Answer: A good record is accurate, factual, legible and timed. Records written this way are reliable and can be used as evidence, for example in court.

  29. In the phonetic alphabet commonly used on the radio, which words represent the letters B and D?

    • ABaker and David
    • BBoston and Denver
    • CBeta and Dog
    • DBravo and Delta✓

    Answer: In the internationally recognised (NATO) phonetic alphabet, B is Bravo and D is Delta. Using a standard alphabet avoids letters being misheard over the radio.

  30. What is the correct way to make a correction to a handwritten entry in an official security notebook?

    • AUse correction fluid to cover the error and write over the top
    • BTear out the page containing the error and start the page again
    • CRule a single line through the error so it stays legible, then initial it✓
    • DRub the mistake out with an eraser, so that no sign of it is left behind

    Answer: Corrections should be made by ruling a single line through the error so it remains legible, then initialling the change. This keeps the record honest and shows that nothing has been hidden.

  31. What is the purpose of clear voice procedure when using a two-way radio?

    • ATo keep messages slow, so that the channel stays occupied as long as possible
    • BTo allow officers to hold private personal conversations over the air between calls
    • CTo encourage the use of slang so that outsiders listening in cannot follow the message
    • DTo pass messages briefly and clearly so that they are understood first time✓

    Answer: Clear voice procedure ensures radio messages are passed briefly and clearly so they are understood the first time. This keeps the channel free and avoids confusion during an incident.

  32. An officer discovers a broken window and signs of a break-in. Before the police arrive, the officer should:

    • Atidy the area and sweep up the broken glass so that no member of staff is injured
    • Bavoid disturbing the scene and keep other people away to preserve evidence✓
    • Chandle the tools left behind to check them for the offender's name
    • Dbegin carrying out repairs to the broken window to make the building secure again

    Answer: The scene should be left undisturbed and other people kept away so that evidence is preserved for the police. Touching items or clearing up can destroy fingerprints and other evidence.

  33. What is the main role of the control room in security operations?

    • ATo coordinate communications, monitor systems and direct the response to incidents✓
    • BTo store the cleaning equipment and spare uniforms for the site
    • CTo provide a quiet rest area where officers can take their breaks
    • DTo securely hold the petty cash that is used for site deliveries, expenses and sundries

    Answer: The control room coordinates communications, monitors systems such as CCTV and alarms, and directs the response to incidents. It is the hub that links officers on the ground with the wider response.

  34. An incident report reads, "the man appeared angry and was probably drunk." What is the best way to improve this entry?

    • ALeave it as written, since an officer's professional opinion counts as evidence
    • BRemove the description of the man's behaviour to keep the report as short as possible
    • CDescribe the observed facts, such as the man shouting, swearing and being unsteady on his feet✓
    • DAdd in the officer's own personal view of how the whole incident really should have been handled

    Answer: Records should state observed facts rather than opinions or assumptions, for example that the man was shouting, swearing and unsteady on his feet. Describing what was actually seen and heard makes the record reliable as evidence.

  35. How can a security officer contribute to good customer service at a site reception?

    • ABy keeping the desk unstaffed so that visitors learn to solve their own problems
    • BBy being approachable, helpful and professional while still maintaining security✓
    • CBy refusing to speak to visitors so that attention stays on the CCTV monitors
    • DBy allowing anyone in without checks so that no visitor is ever delayed

    Answer: An officer supports good customer service by being approachable, helpful and professional while still carrying out security duties properly. Good service and effective security are not in conflict.

  36. A security officer is often the first person a visitor meets on arrival. Why does this matter to the client's business?

    • ABecause the officer would then gain the authority to set the company's prices
    • BBecause it allows the officer to avoid carrying out any security duties
    • CBecause visitors can then be directed to leave without being booked in
    • DBecause the officer's conduct shapes the visitor's first impression of the organisation✓

    Answer: As often the first point of contact, a security officer's conduct and manner shape the visitor's first impression of the whole organisation. Professional, courteous behaviour reflects well on the client's business.

  37. What is the main difference between a static security officer and a mobile patrol officer?

    • AA static officer works day shifts, while a mobile officer is rostered to work the night shifts
    • BA static officer is exempt from SIA licensing, while a mobile officer needs a front-line licence
    • CA static officer holds a door supervisor licence, while a mobile officer holds a CCTV licence
    • DA static officer is based at a single site or post, while a mobile officer travels between sites✓

    Answer: A static officer is based at a single site or post, whereas a mobile patrol officer travels between a number of sites during a shift. Both carry out licensable guarding and need the appropriate SIA licence.

  38. A lone officer must call the control room at set intervals throughout the shift. What is the main purpose of these check-calls?

    • AThey confirm the lone officer is safe, so help can be sent if a call is missed✓
    • BThey keep the radio channel busy so that other officers cannot use it
    • CThey allow the officer to postpone writing up the occurrence book entries
    • DThey let the control room switch the site alarms off between each of the calls

    Answer: Regular check-calls confirm that a lone worker is safe, so that if an expected call is missed the control room can raise the alarm and send help. This is an important safeguard for anyone working alone.

  39. What is the main role of a security officer working in retail loss prevention?

    • ATo help deter and detect theft and reduce stock loss within the store✓
    • BTo set the prices of the goods that are on display for sale in the shop
    • CTo take customers' card payments at the tills during the busiest periods
    • DTo decide the punishment handed to any shoplifter who is caught in the act

    Answer: A retail security officer's main role is to help deter and detect theft and reduce stock loss, often known as shrinkage. Setting prices, taking payments and deciding punishments are not security duties.

  40. How should a security officer manage a contractor who arrives to carry out work on site?

    • AAllow the contractor to roam the site freely, as they are vetted by their own employer
    • BTurn the contractor away, because work on site has to be booked a week ahead
    • CLet the contractor start at once and book in their details after the work is finished
    • DSign the contractor in, confirm the work is authorised, and issue the correct pass✓

    Answer: A contractor should be signed in, their authorisation to carry out the work confirmed, and the correct pass issued before they start. This keeps control of who is on site and what work is taking place.
