Start a Specialist mock test

Pick your specialism below and start a 50-question, 45-minute mock that mixes core questions with questions on your trade. Our Specialist mock gives you 20 questions on your specialism and 30 core questions. CITB's pages we checked do not say how a real Specialist test splits its 50 questions, so treat our split as practice, not a forecast.

Each paper mixes 20 questions on your specialism with 30 from the five core knowledge areas.

Your result shows your score out of 50, your score on the specialism questions and on each core area, and a worked explanation for every question. You can sit 1 free mock every 7 days without an account, or 3 with a free account. A paid plan gives you unlimited mock tests on all 12 specialisms.

CITB runs 12 specialisms, from Supervisory (SUP) to the five HVACR and HVACE papers, and each has its own code. Find yours in the table below, then start a mock for that exact paper. Every question comes with a worked explanation, so you know why an answer is right before you sit the real test. The Specialist test is voiced in English and Welsh only, so practise reading the questions yourself (CITB, checked 25 October 2026). Not a specialist? Go back to the CITB Practice Test and pick Operatives. We are an independent practice site, not CITB, and we do not book tests.

How does a Specialist test work?

A Specialist test uses the core Operatives questions plus questions on the one specialism you book, in the same 50-question, 45-minute test with a pass mark of 45. You choose one specialism when you book. The core questions are the same ones the CITB Operatives Test uses, so a Specialist candidate revises both.

CITB's revision for a Specialist test is the GT100, sections A to E, plus the chapter in section F for your specialism. You are tested on the most recent edition of the revision materials. So the first choice is which of the 12 specialisms is yours.

Which 12 specialisms can you sit?

CITB offers 12 specialisms, each with its own code, from Supervisory (SUP) to HVACE services and facilities maintenance (SAF). Here they are in CITB's order:

CodeSpecialism (CITB name)Practise it

Some people search for the code itself, such as "spec-plum", so every specialism page carries its code in its title or first sentence.

Which Specialist test do you need?

You need the Specialist paper your card application names, and CITB points you to the card finder to check it. CSCS lists the Specialist test for the Gold Supervisor card, and for Blue Skilled Worker and Gold Advanced Craft cards in certain occupations (cscs.uk.com, checked 25 October 2026). For most other Blue Skilled Worker and Gold Advanced Craft cards, CSCS asks for the Operatives test instead.

Applying for the Gold Supervisor card? Check whether the Supervisory (SUP) paper is the one your card needs. No specialism matches your work? Check whether your card asks for the Operatives test instead. Check the card finder before you book, because CSCS wants a pass in the test that matches your card.

Two of the 12 papers, lifts and escalators (LAEE) and tunnelling (TUNN), have no page of their own: you practise both in the next two sections.

What is on the lifts and escalators (LAEE) test?

The LAEE test is the Specialist paper for lifts and escalators: core Operatives questions plus lift and escalator questions, in 50 questions and 45 minutes. CITB's revision for it is the GT100, sections A to E, plus the section F chapter on lifts and escalators.

Our 100 LAEE practice questions each have four answers and a worked explanation. Their most cited sources are these four:

Law or guidance our questions citeOur LAEE questions citing it (of 100)What those questions ask about
HSE L113, the approved code of practice and guidance on LOLER19which law covers a lift or an escalator at work, and how lift doors and safety devices must work
The Lifts Regulations 201618the essential safety requirements for new lifts: suspension ropes, rated load and access to machinery
The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER)12thorough examination, examination schemes and defects reported by a competent person
HSE INDG339, guidance for lift owners6how thorough examination links to maintenance and to in-house inspections

This table shows what our practice questions cite. It is not a CITB syllabus.

Start the LAEE mock test

Sample question 1 · Lifts and escalators

A heavy replacement lift motor is to be lifted into a machine room using a beam and a chain block. Under LOLER regulation 8, who must plan the lifting operation?

  1. A competent personCorrect answer
  2. The operative who will pull the chain block
  3. The building's fire officer
  4. Any operative who holds a valid CSCS card

Why A: LOLER regulation 8(1) requires every lifting operation involving lifting equipment to be properly planned by a competent person, appropriately supervised and carried out in a safe manner. Holding a CSCS card is not the same as being a competent person for planning a lift.

Sample question 2 · Lifts and escalators

A thorough examination of a passenger lift finds a defect which is not yet a danger to people but could become one. Under LOLER Schedule 1, which of these must the report state about that defect?

  1. The name of the engineer who last serviced the lift
  2. The cost of putting the defect right, which could be quoted separately
  3. The time by which it could become a danger to personsCorrect answer
  4. The serial number of the replacement part to be fitted

Why C: Paragraph 8(c) of Schedule 1 to LOLER deals with a defect which is not yet but could become a danger to persons, and requires the report to give the time by which it could become such a danger and particulars of any repair, renewal or alteration required to remedy it. That stated time matters, because regulation 10(3)(b) then bars use of the lift after it passes if the defect has not been put right.

Sample question 3 · Lifts and escalators

The owner of an office block provides a passenger lift that is used by the employees of the firms renting space in it. Who has the LOLER duty to make sure the lift is thoroughly examined?

  1. Nobody, because the tenants' staff are not employed by the owner
  2. The owner of the office block, who provides the liftCorrect answer
  3. Each tenant firm, for the days its own employees use the lift
  4. The lift maintenance contractor, because it services the lift

Why B: L113 gives this example: the owner of an office block who provides a lift for people at work in it has a LOLER duty to ensure the lift is safe and receives periodic thorough examinations.

Sample question 4 · Lifts and escalators

A lift that used to carry light office loads will now carry heavy equipment every day. Under HSE's guidance for lift owners, what should the owner do?

  1. Nothing until the next thorough examination, when the examiner may notice the change themselves
  2. Put a new safe working load sign in the car without telling anyone else
  3. Tell the maintenance contractor but not the examiner, who does not need to know how the lift is being used day to day
  4. Keep the competent person informed of the change, as it may affect their risk assessmentCorrect answer

Why D: INDG339 lists among the dutyholder's responsibilities keeping the competent person informed of changes in the lift operating conditions which may affect the risk assessment.

Sample question 5 · Lifts and escalators

Under the Lifts Regulations 2016, what must the easily visible plate in every lift car clearly show?

  1. The date of the next thorough examination of the lift and its ropes
  2. The name and phone number of the building's facilities manager
  3. The floor numbers served and the speed of the car in metres a second
  4. The rated load in kilograms and the maximum number of passengersCorrect answer

Why D: Schedule 1 paragraph 6(1) requires each car to bear an easily visible plate clearly showing the rated load in kilograms and the maximum number of passengers.

What is on the tunnelling (TUNN) test?

The TUNN test is the Specialist paper for tunnelling: core Operatives questions plus tunnelling questions, in 50 questions and 45 minutes. CITB's revision for it is the GT100, sections A to E, plus the section F chapter on tunnelling.

Our 100 TUNN practice questions each have four answers and a worked explanation. Their most cited sources are these five:

Law or guidance our questions citeOur TUNN questions citing it (of 100)What those questions ask about
The Construction (Design and Management) Regulations 2015 (CDM 2015), Part 421ventilation, emergency routes, ground supports and inspection of underground workings
HSE guidance for appointed doctors under the Work in Compressed Air Regulations 199617the health effects of compressed air work and checks on a worker's fitness
HSE's The heat within: the effect of fire in pressurised tunnels10how a tunnel fire and its smoke behave, and who runs escape and rescue
The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR)9flammable ground gas, hazardous zones and explosion risk
The Confined Spaces Regulations 19975rescue arrangements before anyone enters a shaft or chamber

This table shows what our practice questions cite. It is not a CITB syllabus.

Start the TUNN mock test

Sample question 1 · Tunnelling

Which of these is required by the Work in Compressed Air Regulations 1996?

  1. Records of the workers' exposure are destroyed as soon as the tunnelling project finishes
  2. Alcohol can be taken into the working chamber, provided that the container stays sealed throughout the shift
  3. Medical surveillance is arranged for workers aged over 50, and is not needed for younger ones
  4. HSE gets written notice at least 14 days before work starts, or as soon as practicable in an emergencyCorrect answer

Why D: Regulation 6(1) of the Work in Compressed Air Regulations 1996 says nobody may work in compressed air unless the compressed air contractor has given HSE written notice at least 14 days before the work is to start. Regulation 6(2) allows later notice only where an emergency or unforeseeable circumstances make that impracticable, and even then it must be given before the work starts.

Sample question 2 · Tunnelling

The manual handling assessment for carrying materials along the tunnel must have regard to the working environment. Which of these is a working environment factor listed in Schedule 1 to the Manual Handling Operations Regulations 1992?

  1. Space constraints in the heading that prevent good postureCorrect answer
  2. The age of the person doing the carrying
  3. The make and model of the locomotive that hauls the muck skips
  4. The cost of hiring a mechanical handler instead

Why A: Schedule 1 to the Manual Handling Operations Regulations 1992 lists the working environment factors an assessment must have regard to. They include space constraints preventing good posture, uneven, slippery or unstable floors, variations in floor level, extremes of temperature or humidity, ventilation problems and poor lighting.

Sample question 3 · Tunnelling

Tunnel workers coming out of compressed air sometimes talk about 'the bends' or 'niggles'. What does HSE say these terms describe?

  1. Barotrauma, which is pressure damage to the ears and sinuses during compression
  2. Dysbaric osteonecrosis, which is slow damage to the bone of the hip and shoulder
  3. Heat stress, which builds up during a long shift in the warm air of the working chamber
  4. Type 1 decompression sickness, which most commonly shows as pains around the jointsCorrect answer

Why D: HSE says decompression sickness occurs most commonly in compressed air work as pains around the joints, often referred to as Type 1 decompression sickness, 'the bends' or, if less severe, 'niggles'.

Sample question 4 · Tunnelling

High voltage cables run along a tunnel to power the tunnel boring machine. Where necessary to prevent danger, what does CDM 2015 require of such energy distribution installations?

  1. They must be switched off at the end of the shift and at weekends
  2. They must be buried under the tunnel invert so that nobody can touch them
  3. They must be inspected by the client before the tunnel drive starts
  4. They must be suitably located, periodically checked and clearly indicatedCorrect answer

Why D: Regulation 25(1) says that where necessary to prevent danger, energy distribution installations must be suitably located, periodically checked and clearly indicated.

Sample question 5 · Tunnelling

Several locomotives run on the same track in a tunnel at the same time. What does PUWER regulation 28 require of them?

  1. A radio in each loco tuned to a local music station for the drivers
  2. A single driver who moves between the locos as they are needed
  3. Horns that sound continuously whenever the locos are moving
  4. Appropriate facilities for minimising the consequences of a collisionCorrect answer

Why D: PUWER regulation 28(b) requires self-propelled work equipment to have appropriate facilities for minimising the consequences of a collision where more than one item of rail-mounted work equipment is in motion at the same time.

The LAEE and TUNN questions are written and checked by the CITB Practice Test Team against the sources above.

How is a Specialist test different from the Operatives test?

A Specialist test adds questions on your trade, and you can hear it only in English or Welsh, while the Operatives test has 14 voiceover languages. Everything else about the format is the same:

Specialist test FAQs

Each answer below was checked against citb.co.uk on 25 October 2026.

Can you take the Specialist test online?

No. Specialist tests run at a Pearson Professional Centre or an Internet Test Centre, as every CITB HS&E test does. CITB lists no at-home option for the HS&E test. CITB also runs a mobile testing service for group bookings.

Does the Specialist test cost more than the Operatives test?

No. Every CITB HS&E test costs £23.50. The fee is the same for all 12 specialisms, and CITB does not let you re-sit within 48 hours of a fail.

How hard is the Specialist test?

You still need 45 out of 50, so practise your specialism questions as well as the core ones. A full timed mock for your code shows which half cost you marks.
