HSC Calculator Rules 2026: Check Your Model Before Exam Day
For a 2026 HSC exam, your calculator must be approved for that exam year and permitted in the particular course. Check the full model name, including any letters, numbers or edition details. A familiar brand or a shop’s “school calculator” label is not enough.
Start with NESA’s approved-calculator page and your school’s advice. Do this with the device in your hand so you are checking the calculator you will actually bring, rather than the model you remember buying.
Watch the approval year on the live list
There is an important detail for this year’s students: NESA’s live page now sits under a 2027 web address, even though the 2026 guide links to it. Its approval-process section says newly approved calculators can be used from the following year, giving 2026 approvals for the 2027 HSC as an example.
Consequently, do not assume a newly added model is automatically approved for your 2026 exam. If you are replacing a calculator, buying a new release or uncertain about a suffix, ask your school to confirm the exact model’s 2026 eligibility before purchasing or relying on it.
A useful question is: “This is the complete model name on my calculator. Can you confirm it is approved for my 2026 HSC course?” That gives the teacher something precise to check.
Check the subject as well as the device
The course equipment list identifies which exams permit calculators. It includes the mathematics courses and several sciences, but an approved calculator is not permission to use one in every paper.
Look up each remaining course separately. If you have an approved accessibility arrangement, confirm the device and exam-day procedure with your school rather than applying a general checklist to your situation.
Practise the operations you will need
A calculator you have used all year is generally easier to navigate than an unfamiliar replacement. Test the functions relevant to your course using short questions with answers you can check independently.
Enter a fraction with a multi-term numerator and denominator, checking the brackets.
Calculate a negative number raised to a power and distinguish it from a negative sign outside the power.
Move between exact and decimal forms where your calculator supports it.
Check how to select the angle unit required by a trigonometry question.
For instance, in degree mode, sin 30° should give 0.5. That is a quick practice check of a setting, not a reason to leave the calculator permanently in degrees. Some questions require radians. Read the question and select the appropriate mode once equipment use is allowed.
Prepare for the required reset
NESA requires calculators to be switched off and reset before entering. Calculator lids, instruction booklets and reference cards cannot come into the exam room. Learn your model’s reset procedure ahead of time and practise restoring any settings you need afterwards.
At home, check the display, keys and battery condition using the manufacturer’s instructions. Do not experiment with repairs on exam morning. If you need another device, allow time to check its approval and practise with it.
If you plan to bring a spare, check arrangements with your school and apply the same model, working-order and reset checks to that calculator. A spare you cannot operate confidently may not solve the problem you hoped to avoid.
If it stops working during the exam
Alert the supervisor and follow their instructions. Do not borrow another student’s equipment. NESA says equipment failure is not grounds for an upheld misadventure application; you should not expect a replacement or extra time.
For revision, official exam packs help you practise calculator use alongside written methods. If calculator entry or settings repeatedly interrupt your working, you can ask North Shore Tutors about focused help through one-to-one tutoring.
