What Happens If There Is a Disruption During an HSC Exam?
Learn what to do if noise, interruptions or procedural errors disrupt your NSW HSC exam. Understand how to report an incident, follow up through your school, and apply for NESA illness and misadventure consideration without assuming a mark adjustment is guaranteed.
A fire alarm sounds halfway through your Mathematics Advanced exam. A construction crew starts drilling outside the exam room. Or a supervisor gives the wrong instruction about when to begin writing.
Your first thought might be that NESA will automatically compensate everyone affected. That's not how it works.
**If something disrupts your HSC exam, tell the Presiding Officer or exam supervisor immediately.** Ask them to record what happened, when it happened, and how it affected the exam. Then contact your school principal as soon as possible after the exam to discuss whether further action is needed.
A disruption being recorded is important, but it does not guarantee extra marks, additional time, or a change to your examination result. The next step depends on what happened and which official process applies.
## What counts as a disruption during an HSC exam?
A disruption is an unexpected event or problem that interferes with the normal conduct of your examination.
Some disruptions are external. Others involve the way the examination is being administered.
Common examples include:
| Type of disruption | Examples |
|---|---|
| External noise | Construction, roadworks, sirens, or loud machinery |
| Unexpected interruptions | A fire alarm, emergency announcement, or an interruption caused by an incident outside the room |
| Room conditions | A significant problem with lighting, ventilation, or the examination environment |
| Procedural problems | Incorrect instructions, a delayed start, or confusion about examination timing |
| Examination materials | Missing pages, an incorrect paper, or a problem with materials supplied to students |
Not every inconvenience is automatically grounds for a formal application. The important questions are whether something unexpected happened, whether it was outside your control, and whether it affected your ability to complete the examination.

## What should you do when a disruption happens?
Your priority is to make sure the problem is brought to the attention of the person responsible for the examination.
That person is usually the Presiding Officer or an exam supervisor.
Don't wait until you get home to mention it. If the problem is happening during the examination, report it while it is happening.
### Step 1: Raise your hand and notify a supervisor
Explain the problem calmly and specifically.
For example:
- "There has been loud drilling outside the room for the last few minutes."
- "The fire alarm interrupted the examination while we were writing."
- "I think the starting instruction was given before we were told to begin."
- "My examination paper appears to be missing a page."
You do not need to argue that the incident deserves extra marks. You need to make sure the supervisor knows what happened.
### Step 2: Ask for the incident to be recorded
Explain when the disruption started, how long it lasted if you know, and what part of the examination it interrupted.
If several students were affected, make that clear.
You can ask whether the Presiding Officer will document the incident and whether any further instructions will be given. The examination staff are responsible for managing the examination room and its procedures.
Don't assume that someone else has reported the problem on your behalf.
### Step 3: Follow the supervisor's instructions
The Presiding Officer and exam supervisors are responsible for administering the examination. Follow their directions about continuing, pausing, moving rooms, or dealing with incorrect examination materials.
Don't leave your seat, speak to other students, or try to resolve a procedural issue independently.
If the disruption is serious, the examination staff can manage the response. Your job is to report what you experienced and follow the instructions given.
### Step 4: Contact your school after the examination
Tell your principal what happened, even if you believe the examination staff have already documented it.
Give a factual account while the details are fresh. Include the examination, approximate time, duration, nature of the disruption, and how it affected your work.
Ask your school whether you should take any further action under NESA's procedures.

01NESA’s rules about noise and examination conditions
Noise is not something students are simply expected to tolerate without question.
Under NESA’s ACE Rules for conducting HSC exams, schools must provide examination rooms that are:
- adequately lit and ventilated
- free from as much external noise as possible
- accessible to all students.
NESA also requires external disturbances to be kept to a minimum. Its rules specifically identify school bells and noisy playgrounds near examination rooms as examples of external disturbances.
This gives you a clear basis for reporting significant noise. However, it does not mean that every unexpected sound automatically qualifies for an illness or misadventure application.
There is an important distinction between two things:
- The examination environment did not meet the expected conditions.
- The disruption was significant enough to diminish your individual examination performance.
The first can justify reporting an incident. The second is relevant to whether you may qualify for further consideration under NESA’s illness and misadventure process.
02When does a disruption qualify for illness and misadventure?
This is where the distinction becomes important.
NESA’s illness and misadventure process is not a general complaints system. It is designed to support students whose examination performance has been affected by circumstances beyond their control.
For an application to be considered, the event must meet the relevant eligibility requirements.
Under NESA’s 2026 Rules and Procedures, the illness or misadventure must:
- have occurred immediately before or during an HSC examination
- have been unexpected
- have been beyond your control
- have prevented you from attending the examination or diminished your examination performance.
Consider the difference between these situations:
| Situation | How to approach it |
|---|---|
| Unexpected construction noise continues during your exam and significantly affects your concentration. | Report it immediately and discuss an individual or group application with your principal. |
| A fire alarm interrupts the examination and students have to evacuate. | Report the incident and follow the school’s and Presiding Officer’s instructions. The school may need to consider a group application. |
| A supervisor gives an incorrect instruction about examination timing. | Report the procedural error immediately and ask the Presiding Officer to document what occurred. Discuss the impact with your principal. |
| You misunderstand a written examination instruction. | NESA specifically excludes misreading examination instructions from illness and misadventure applications. |
| You find your calculator is not working because you failed to check it beforehand. | Equipment failure is not an eligible reason for an illness and misadventure application. |
Notice the difference between receiving an incorrect instruction and misreading an instruction yourself.
If a supervisor gives the wrong direction, that is a procedural issue outside your control. You should report it. Whether it meets the requirements for an illness and misadventure application depends on the circumstances and evidence.
If you simply misunderstand the question paper or its instructions, NESA’s rules specifically exclude that situation.
The full requirements are explained in NESA’s 2026 Rules and Procedures guide.
03How does the school’s official follow-up process work?
Reporting the incident is the first part of the process. If your performance was affected, the next step may be an individual or group illness and misadventure application.
These are two different application pathways.
Individual illness and misadventure applications
An individual application is appropriate when you believe an unexpected event diminished your own examination performance.
NESA requires an individual application to include several forms of information.
1. Your own account
You must explain how the event affected you during the examination and complete the student declaration.
Be specific. Instead of writing that the noise was distracting, explain when it occurred, how long it lasted, and what happened to your ability to complete the paper.
2. The Presiding Officer’s report
For a written examination, the school’s section of the application includes a report from the Presiding Officer.
This report outlines observable signs noticed by examination supervisors during the exam.
For example, a supervisor may have observed an interruption, a student reporting a problem, or an incident affecting the examination room.
This is one reason reporting the problem at the time matters. It gives the examination staff an opportunity to observe and document what is happening.
3. Independent supporting evidence
NESA also requires independent evidence explaining how the misadventure may have affected your examination performance.
For misadventure, the evidence must identify the event and include the relevant dates and times. NESA’s ACE Rules give police statements and statutory declarations as examples of supporting evidence.
Ask your principal what evidence is appropriate for your particular situation. The requirements depend on the nature of the event.
Group illness and misadventure applications
What happens if an entire examination room is affected?
You might assume that every student needs to submit an individual application. That is not necessarily the case.
NESA has a group illness and misadventure process for situations where an entire course candidature, or a proportion of it, is affected by the same event.
The principal is responsible for submitting the group application.
The principal must:
- provide a detailed description of the incident
- explain how the event affected the students involved
- identify only the students who were actually affected
- account for students from other schools who were sitting the examination at that centre, where applicable
- encourage students who were particularly affected to submit individual applications.
For example, if an emergency evacuation interrupts an examination, the principal may submit a group application for the affected students.
However, a student who was accommodated elsewhere before the incident should not automatically be included simply because they were entered for the same examination.
The distinction is between being present at the examination centre and actually being affected by the incident.
How quickly do you need to act?
Don’t leave the paperwork until the end of the exam period.
For the 2026 HSC cohort, NESA’s detailed ACE Rules specify that students must submit individual applications to their principal:
- within five business days after the affected examination, or
- within three business days after the HSC examination period concludes,
whichever comes first.
The 2026 Rules and Procedures guide also states that schools must lodge written-examination illness and misadventure applications with NESA within one week of the affected examination.
These are separate stages of the process. Your principal needs time to prepare and submit the school’s section, so get your application to them promptly.
If several examinations have been affected, speak to your principal about the correct application arrangements rather than assuming you can wait until the end of the period.
NESA’s Illness/Misadventure ACE Rules explain the individual and group application requirements in more detail.
04Two examples: what should happen next?
Let’s put the process into situations you might actually encounter.
Example 1: Construction noise during a Physics exam
You’re sitting a Physics examination. About halfway through the paper, loud drilling starts outside the examination room.
It continues intermittently, making it difficult to concentrate on a longer calculation question.
You raise your hand and tell the supervisor. The Presiding Officer acknowledges the problem.
What should you do after the examination?
You should:
- Write down the approximate time the drilling started and stopped.
- Explain to your principal how it affected your examination performance.
- Ask whether the Presiding Officer has documented the disturbance.
- Ask whether the school considers a group application appropriate.
- If your individual performance was significantly affected, ask for an individual illness and misadventure application.
The fact that other students heard the same noise does not mean everyone experienced the same impact.
NESA considers the evidence and the circumstances of the students included in an application. A short period of noise, for example, does not automatically justify an adjustment to examination results.
Example 2: A supervisor gives an incorrect timing instruction
Imagine that a supervisor mistakenly tells the examination room to stop writing before the scheduled finishing time.
After checking the clock, the Presiding Officer realises the mistake and corrects the instruction.
Some students have already stopped working. Others continue once the correction is made.
What should you do?
First, report the incorrect instruction to the Presiding Officer. Make sure the actual sequence of events is clear:
- when the incorrect instruction was given
- when it was corrected
- whether writing time was restored
- whether the incident affected your ability to complete the examination.
After the exam, speak to your principal and ask whether an individual or group application should be considered.
The correction is relevant evidence, but it does not automatically resolve the issue. Some students may have lost time or concentration even after the instruction was corrected.
Equally, the fact that an error occurred does not establish that every student suffered a diminished performance.
NESA makes the final decision using the evidence provided.
05Does NESA give you extra marks if your application is approved?
No. An upheld illness and misadventure application does not mean NESA simply adds marks to your examination result.
Instead, NESA uses a calculation process to determine an appropriate examination mark.
Depending on the course and the circumstances, this may involve your moderated school assessment mark, an estimated examination mark, or unaffected examination components.
NESA then awards the higher of the calculated examination mark and the mark you actually achieved.
This distinction is important.
Consider two possible outcomes:
- Your actual examination performance is higher than the calculated mark. You retain your actual examination mark.
- The calculated examination mark is higher than your actual examination mark. You receive the calculated mark.
The process is designed to avoid disadvantaging students whose performance was genuinely affected. It is not designed to reward students with additional marks simply because an incident occurred.
If NESA declines your application, you do not receive this alternative calculation. You retain the examination mark you achieved if you attended the exam.
You can read the details in NESA’s explanation of illness and misadventure.
06Does reporting an incident affect your ATAR or university application?
It’s useful to separate three different organisations and their responsibilities.
| Organisation | Responsibility |
|---|---|
| NESA | Manages HSC examinations, assesses illness and misadventure applications, and determines HSC results. |
| Your school | Helps you complete the application, provides relevant reports, and submits individual or group applications to NESA. |
| UAC | Calculates your ATAR and manages applications and offers for participating universities and institutions. |
You do not report an examination-room disturbance to UAC instead of NESA.
UAC specifically states that illness or misadventure affecting final Year 12 examinations is not considered under its Educational Access Scheme (EAS). NESA has a separate process for these circumstances.
There is another important point: if NESA provides UAC with amended HSC results, UAC automatically recalculates your ATAR and notifies you by email.
Any separate university admission adjustment is a different matter. Institutions have their own selection policies, and eligibility for an adjustment does not guarantee an offer.
You can read more through UAC’s official guides to ATAR calculations and Educational Access Scheme eligibility.
07What if you only realise the impact after leaving the exam?
Ideally, you should report the incident during the examination.
However, you might only realise how significantly it affected your work after leaving the room.
For example, you may remember that an interruption caused you to lose track of a multi-step calculation, or that an incorrect instruction meant you did not return to a question you had intended to finish.
Contact your principal immediately.
Explain what happened, why you did not report it during the exam, and how it affected your performance. Ask whether you can still submit an application and what evidence is required.
NESA expects students to take action immediately. Delaying notification can make an application harder to assess, particularly if there is no contemporaneous report from examination staff.
You should not assume that an application will be rejected simply because you did not raise the issue at the time. However, you should not assume it will be accepted either.
If an individual illness and misadventure application is declined, NESA’s ACE Rules allow students to appeal. An appeal must explain the reasons for the appeal and include new supporting evidence.
A NESA Results Check is a separate service. It checks whether examination marks have been processed correctly; it does not re-mark your answers or review the conditions in which you sat the exam.
08Your practical checklist after an HSC exam disruption
You don’t need to memorise every NESA rule. You do need to know what to do while the incident is happening and what to follow up afterwards.
During the examination
- Raise your hand and notify the supervisor.
- Explain the problem clearly.
- Note the approximate time and duration.
- Ask whether the Presiding Officer has documented the incident.
- Follow all instructions about continuing or pausing the examination.
After the examination
- Contact your principal promptly.
- Write down a factual account of what happened.
- Explain how your examination performance was affected.
- Ask whether an individual or group application is appropriate.
- Obtain the supporting evidence required by NESA.
- Submit your individual application within the applicable deadline.
- Keep your application acknowledgement and check Students Online for the outcome.
For routine exam preparation, the HSC Exam Day Checklist: What to Pack and Check covers the equipment and practical checks you should complete before entering the examination room.
09Questions and solutions
Question 1
You’re sitting a Mathematics Advanced examination when loud construction noise begins outside the examination room. It continues for several minutes.
What is the most appropriate immediate response?
Solution 1
Raise your hand and notify the exam supervisor immediately.
Explain what is happening and, if possible, when the disturbance started. Ask whether the Presiding Officer will document the incident.
NESA requires examination venues to minimise external noise and disturbances. However, reporting the noise does not automatically qualify you for an illness and misadventure application.
If you believe your performance was affected, speak to your principal after the examination about the appropriate follow-up process.
Question 2
During reading time, you misunderstand an instruction and begin writing before you are permitted to do so. You realise your mistake and stop when instructed.
Can you apply for illness and misadventure because the confusion affected your examination?
Solution 2
No, not on the basis of your own misreading of the examination instructions.
NESA explicitly excludes misreading examination instructions from its illness and misadventure process.
The important distinction is who caused the procedural problem. A student misunderstanding an instruction is different from a supervisor giving an incorrect instruction to the examination room.
You should still follow the supervisor’s directions and report any genuine procedural error. However, you cannot treat your own misunderstanding as an unexpected external misadventure.
Question 3
During a Chemistry examination, the supervisor mistakenly announces that writing time has ended several minutes before the scheduled finishing time.
The Presiding Officer identifies the error and tells students to continue writing.
Some students say the mistake affected their ability to finish the paper.
Does the correction mean there is no longer a reason to report the incident?
Solution 3
No. The incorrect announcement should still be reported and documented, even though it was corrected.
The correction is an important part of the evidence, but it does not establish that every student was unaffected.
Students should explain whether they stopped writing, how long they stopped for, and whether the correction allowed them to recover the lost time and concentration.
The principal can consider whether an individual or group illness and misadventure application is appropriate.
The fact that the instruction came from a supervisor, rather than being misread by a student, is an important distinction. NESA must still determine whether the event meets the eligibility requirements and whether the evidence demonstrates diminished performance.
Question 4
A fire alarm interrupts an HSC examination. Students in the main examination hall are evacuated, while students in an adjacent room remain seated and continue working.
The principal is considering a group illness and misadventure application.
Should every student at the examination centre automatically be included?
Solution 4
No. The group application should identify the students whose examination performance was actually affected by the event.
NESA’s ACE Rules require the principal to use professional judgement when determining which students have been impacted by the same incident.
The students evacuated from the main hall may have experienced an interruption to their examination. However, the students in the adjacent room should not automatically be included just because they heard the alarm.
Some students in the adjacent room may also have been affected. Their circumstances should be considered on the evidence rather than assumed to be identical.
Students who were particularly affected may also submit individual applications.
The important point is that a group application is not a blanket adjustment for everyone sitting at the same examination centre.
Question 5
An examination centre hosts students from several schools.
During a Physics examination, a fire alarm sounds. Students in Room A are evacuated, while students in Room B remain inside. Both rooms are affected by the alarm, but the interruption is more significant in Room A.
After the exam:
- One student from Room A tells the principal they were not significantly affected.
- Another student from Room A reports that the interruption severely affected their ability to finish the examination, but they did not notify the supervisor at the time.
- A third student from Room A was visibly distressed, and the supervisor noticed this during the incident.
- Several students from Room B say they heard the alarm but continued working without interruption.
The principal proposes submitting one group application covering every student at the examination centre.
What should happen instead? Explain how the principal should handle the group application, which students might need individual applications, and why the timing of the reports matters.
Solution 5
The principal should not automatically include every student at the examination centre. The application must reflect which students were actually affected and how the incident influenced their examination performance.
There are several separate issues to resolve.
First, identify the affected course candidature.
NESA’s group application process applies when an entire course candidature, or a proportion of it, is affected by the same event.
The principal should document the fire alarm, the evacuation, the examination interruption, and the impact on the relevant students.
Students in Room A are likely to have experienced the most direct interruption. However, the principal should still use evidence to identify who was affected rather than assume every student experienced the same disadvantage.
Students in Room B should not automatically be included. Hearing an alarm does not necessarily mean their examination performance was diminished.
Second, consider the individual circumstances.
The student who says they were not significantly affected should not automatically be included in the group application simply because they were evacuated.
The student who experienced severe difficulty but reported it only after leaving the room should contact the principal immediately and ask about an individual application. The delay may make the claim harder to establish, but the student should not assume that they have no possible route forward.
The third student has an important piece of supporting information: the supervisor observed visible distress during the incident. NESA’s individual application process requires a Presiding Officer’s report outlining observable signs noticed by supervisors during written examinations.
That observation may help support the student’s account, although it does not guarantee approval.
Third, account for students from other schools.
The principal must identify students from other schools who were sitting the affected examination at the centre and notify their home-school principals, as required by NESA’s group application rules.
Finally, let NESA make the decision.
The principal submits the group application with a detailed description of the incident and its impact. Students who were particularly affected should be encouraged to submit individual applications with their own statements and supporting evidence.
The tempting approach is to treat the fire alarm as one event that affected everyone equally. The actual requirement is more precise: the school must identify the students whose performance was affected, and NESA must assess the evidence.
That is why reporting the incident immediately, recording the details, and explaining your individual experience are so important.
An unexpected interruption can make an HSC examination much harder than it should have been. You are entitled to report the problem and ask your school to follow the appropriate NESA process.
Just remember the distinction: a documented incident is evidence of what happened, not a promise that your examination mark will change.
The most useful thing you can do is report the problem immediately, give your principal a clear account, and make sure any application is supported by the evidence and submitted within the required timeframe.
