Cert IV Auto Diagnostic exam-day guide
Cert IV Auto Diagnostic · Prepare for the day ahead.
Your checklist
Photo ID
Bring the original government-issued photo ID you used to enrol. Check the name matches your enrolment record exactly. If you have changed your name or your ID is expired, confirm with the provider in advance what alternative evidence they accept.
Assessment booking confirmation
Print or save a copy of your booking confirmation showing date, time, campus or venue, and any candidate number. Confirm with the provider whether arrival time is earlier than the start time.
Enrolment and prerequisite evidence
Bring evidence of completed prerequisite units or course enrolment if the provider requires it on the day. Confirm with the provider which documents must be originals versus copies.
Personal protective equipment
Practical automotive assessments normally require safety boots, safety glasses, and hearing protection, plus any clothing the provider specifies. Ask the provider for the exact PPE list for your assessment, since requirements vary by task and workshop.
Workwear and hair/ jewellery restrictions
Wear long sleeves and trousers suitable for workshop work. Remove or secure loose jewellery, and tie back long hair. Confirm with the provider if overalls are supplied or must be your own.
Required hand tools
Ask the provider whether you use the workshop's tools or bring your own set. If your own tools are required, bring a complete set and check it against the tool list supplied in your course materials.
Logbook or workplace evidence
If your qualification includes a logbook, job cards, or supervisor sign-offs, bring the completed originals in the required format. Confirm with the provider the deadline and whether copies are accepted.
Knowledge of assessment conditions
Read your assessment plan or student handbook for time limits, permitted reference material, and the number of attempts. Confirm with the provider anything that is unclear rather than assuming.
Calculator and writing materials
Bring a basic calculator and pens if the assessment includes written tasks or calculations. Confirm with the provider whether programmable calculators or phones are prohibited.
Medication and personal needs
Bring any medication you may need and tell the assessor about relevant medical conditions or adjustments approved in advance. Confirm with the provider how approved adjustments will be applied on the day.
Transport and arrival plan
Plan to arrive with time to spare, allowing for traffic and parking. Check public transport or parking options for the venue the day before. Confirm with the provider the latest acceptable arrival time.
Rest and preparation
Get a normal night's sleep and eat before you arrive. Practical assessments are physically demanding and run for extended periods, so avoid last-minute cramming that leaves you tired.
Plan the day
Re-read the assessment plan and task list so you know exactly which practical tasks and knowledge questions are being assessed. Confirm the venue, start time, and PPE requirements with the provider. Check that your logbook or workplace evidence is complete and signed, and chase any missing signatures now rather than on the day.
Do a final tool and equipment check against the course tool list. Replace anything missing or damaged. Practise the diagnostic procedures you are least confident in, focusing on the sequence of tests and how you will record results, not on memorising answers.
Pack your bag: ID, booking confirmation, PPE, workwear, tools, logbook, pens, and calculator. Lay out clothes for the morning. Confirm your transport plan and check for roadworks or timetable changes. Set two alarms.
Stop heavy study in the evening. Eat a proper meal, avoid alcohol, and go to bed at a normal time. If you feel unwell, contact the provider before the day to ask about illness or deferral options rather than arriving symptomatic.
Eat breakfast, arrive early, and allow time to sign in and store your belongings. Present your ID when asked. Listen carefully to the assessor's briefing on safety, housekeeping, and what to do if you need to stop a task.
Work to the task instructions and the workshop's safety procedures. Verbally state what you are checking and why, and record measurements and observations as you go. If a task is unclear, ask the assessor for clarification on the instruction, not for the answer. Manage your time so you complete every task rather than perfecting one.
If you make an error, stop, make the situation safe, and tell the assessor. Follow their direction on whether the task can be restarted. If you need a toilet break or feel unwell, tell the assessor immediately rather than leaving the area unannounced.
Hand in any written materials or logbooks as directed. Ask the assessor what happens next and when results are expected. Note anything you found difficult while it is fresh, so you can address it before any resubmission or gap training.
Rules to check
Bring the original photo ID used at enrolment and present it when asked. If your ID is unavailable, expired, or shows a different name, confirm with the provider before the assessment what alternatives are accepted.
Follow all workshop safety directions from the assessor. Wear the specified PPE for every task, isolate and make safe any vehicle or equipment before working on it, and report hazards or injuries immediately. An unsafe act can end your assessment.
Ask the assessor to clarify task instructions if they are unclear, but do not ask for answers or accept help from other candidates. All work you submit or perform must be your own.
Mobile phones and smart devices are commonly restricted during assessments. Confirm with the provider where devices must be stored and whether any use is permitted during breaks.
Break arrangements vary by provider and task length. Confirm with the provider in advance how breaks are managed and how to request one during the assessment, and tell the assessor if you need to stop for health reasons.
Scoring is against the assessment requirements for each task, and most practical tasks are marked as satisfactory or not yet satisfactory rather than with a percentage. Confirm with the provider the pass requirements, the number of attempts allowed, and the resubmission process.
If you are ill, injured, or unable to attend, contact the provider as early as possible to ask about deferral or special consideration. Do not attend with an infectious illness or an injury that prevents safe workshop work.
Treat assessors, staff, and other candidates respectfully. Follow the provider's rules on academic integrity and on what reference material, if any, may be used during knowledge tasks. Confirm any unclear rule with the provider before the day.
