What does HSC stand for?

HSC stands for Higher School Certificate. It is the credential NSW students earn at the end of senior secondary school, awarded by NESA (the NSW Education Standards Authority) under the Education Act 1990 (NSW). It covers a two-year program: Year 11 (the Preliminary pattern of study) and Year 12 (the HSC pattern of study).

How many units do you need for the HSC?

NESA's 2026 rules require a Preliminary pattern of study of at least 12 units and an HSC pattern of study of at least 10 units. Each pattern must include at least 2 units of a Board Developed English course, 4 more units of Board Developed courses, 3 courses of 2 or more units (Board Developed or Board Endorsed) and 4 subjects.

Do you have to sit the HSC exams to get the HSC?

Yes, for the courses that have an HSC exam. NESA requires you to sit for, and make a serious attempt at, the required HSC exams. Answering only the multiple-choice questions is not a serious attempt. If you miss an exam without an accepted illness/misadventure application, you can lose the course, and losing enough units can make you ineligible for the HSC.

Can you take longer than two years to complete the HSC?

Yes. NESA allows you to accumulate your HSC over up to five consecutive years, counted from the first year you complete an HSC course. You can also repeat courses within those five years, and start an HSC course early and bank the result before Year 12.

How many take-home tasks can a school set in HSC assessment?

One, and it can be worth no more than 15% of the assessment mark. NESA also advises that each individual task carry between 10% and 40%. Your school's assessment schedule sets the actual weightings.

Do you need an ATAR to get the HSC?

No. The HSC is NESA's certificate and the ATAR is a separate rank that UAC calculates for university admission. NESA says getting an ATAR is optional, and students who do not plan to go to university the following year can choose not to request one. ATAR eligibility has its own rules, set by UAC.

Does the HSC include a literacy and numeracy requirement?

Yes. Among the eligibility requirements NESA lists is demonstrating the minimum standard of literacy and numeracy. The 2026 Rules and Procedures name this requirement but do not explain how it is met, so ask your school or check NESA's HSC minimum standard information.

What Is the HSC? How the Higher School Certificate Works (NESA)

The HSC (Higher School Certificate) is the credential NSW students earn at the end of Year 12, awarded by NESA. To get it you complete a Year 11 (Preliminary) and Year 12 (HSC) pattern of study, meet the eligibility rules, and sit the required exams. In most courses with an HSC exam, your mark for the course is half your school assessment (moderated by NESA) and half your exam. The ATAR is a separate rank that UAC calculates afterwards.

This guide describes the rules in NESA's 2026 HSC Rules and Procedures, UAC's ATAR Essentials 2026 and NESA's results information, which apply to students completing the HSC in 2026. NESA publishes its rules and dates in Students Online and on its website, so check them for your own year.

What is the HSC?

The HSC is a certificate, not a score. NESA, the NSW Education Standards Authority, is empowered by the Education Act 1990 (NSW) to make and enforce the rules for it. You study for it over two years: the Preliminary courses in Year 11 and the HSC courses in Year 12.

It is made of separate course results. Each course you complete gets its own mark out of 100 and a performance band. Your testamur (the certificate itself) is posted from the end of January to students who are eligible, and your results are also available in Students Online.

Three organisations get confused, so here is who does what:

NESA sets the HSC rules, sets and marks the HSC exams, moderates school assessment marks and reports your results.
UAC (Universities Admissions Centre) calculates your ATAR. NESA says the ATAR comes to students from UAC and does not appear in Students Online.
Your school teaches the courses, sets the school-based assessment tasks and certifies that you completed each course.

What do you need to be eligible for the HSC?

NESA lists what an HSC student must do. In summary:

Requirement	What it asks for
Year 10	Completed Year 10 or its equivalent recognised by NESA.
Where you study	A NSW government school, an accredited non-government school, TAFE NSW or a school outside NSW recognised by NESA.
All My Own Work	Complete the All My Own Work program or its equivalent (not required if your whole pattern is Life Skills courses).
Patterns of study	Satisfactorily complete a Year 11 (Preliminary) and Year 12 (HSC) pattern of study.
Literacy and numeracy	Demonstrate the minimum standard of literacy and numeracy.
Exams	Sit for, and make a serious attempt at, the required HSC exams.

The pattern of study has minimum sizes. The Preliminary pattern needs at least 12 units and the HSC pattern needs at least 10 units. Both patterns must include at least:

2 units of a Board Developed course in English
4 more units of Board Developed courses
3 courses of 2 or more units (Board Developed or Board Endorsed)
4 subjects

Some courses cap how many units can count, for example a maximum of 6 units of Science in the Preliminary pattern and 7 in the HSC pattern. Each syllabus lists its own exclusions.

Your school enters you for every course you study, including any VET or distance education course your principal approves, on a Confirmation of Entry. It shows the courses, and whether you are eligible for an HSC and an ATAR. You sign it (usually digitally, in Students Online), which certifies you have read the Rules and Procedures.

NESA's rules name the minimum standard of literacy and numeracy as a requirement but do not explain how it is met. Ask your school about the current process.

How is an HSC mark made?

For most Board Developed Courses with HSC exams, school-based assessment is 50% of your HSC mark. Your HSC mark in a course is the rounded average of two numbers, your exam mark and your moderated assessment mark.

The assessment mark. Your school gives you tasks across the course, such as tests, written or oral assignments, practical activities, fieldwork and projects. NESA sets which components are assessed and their weightings in each syllabus, and your school sets the individual tasks and due dates. At the end of the program, the school sends your assessment marks to NESA.

Moderation. NESA then moderates the marks, which means adjusting them so they sit on the same scale as your school group's exam marks in that course. This allows a fair comparison between schools. Each school group's marks are adjusted by how that group performs in the HSC exam, and NESA does not change the rank order your school submits. You can see your assessment rank in Students Online after your last exam, and only the rank can be appealed, never an individual task mark.

The exam mark. NESA sets and marks the exam. Depending on the course, it can include a written paper, speaking and listening exams, practical exams or major works submitted for external marking. Your result is reported against set standards for the course, not compared with other students, so it reflects the standard you reached. For how bands are set, see the HSC bands guide.

A few courses work differently. English Studies and Mathematics Standard 1 results are a grade from A to E submitted by your school, unless you sit the optional HSC exam. If you do, your result is the exam mark and a performance band.

For release dates, the results you receive and what to do if you disagree with a mark, see the HSC results guide.

What limits apply to school assessment tasks?

Your school decides the number and type of its tasks, but NESA's guidance is that an individual task carries between 10% and 40% of the assessment mark, and a school may set only one take-home task, worth no more than 15%. Your school's assessment schedule is where your actual task weightings are. Trials are one common task: see HSC trials and trial papers for how they feed your mark and rank.

What do the HSC exams involve?

The 2026 written exams run from Tuesday 13 October to Thursday 5 November. Other exams fall outside that window: language orals are in Term 3, and performance exams and submitted works such as Dance, Drama, Music, Design and Technology and Visual Arts happen before or outside the written period.

Some rules apply to every exam:

The start time printed on your timetable is when reading time begins, and reading time is reading only.
You cannot leave in the first hour or the last 15 minutes.
Only NESA-approved scientific calculators are allowed. No programmable, graphing, CAS or financial calculators are permitted in any HSC exam.
If you miss an exam because you misread your timetable, contact your principal immediately. You cannot apply for illness/misadventure on those grounds.
Unauthorised use of generative AI tools is malpractice.

If you miss an exam for a reason beyond your control, your school can lodge an illness/misadventure application with NESA within one week. If the course has only one component and NESA declines the application, you get no result for the course.

For how to prepare and what NESA's markers keep saying, see how to prepare for HSC exams. To practise on real papers, see HSC past papers.

Can you take more than two years to finish the HSC?

Yes. The standard route is two years, but NESA recognises other pathways:

Pathway	What it means
Accumulating	Take up to five consecutive years to finish, counted from the first year you complete an HSC course.
Repeating	Repeat courses within the five years without penalty. UAC calculates the ATAR from your most recent HSC results if you are eligible.
Credit transfer and recognition of prior learning	TAFE or other institution courses can count as credit transfer, and prior learning can excuse some components.
Accelerating	Complete an HSC course and sit its exam before Year 12, including starting a Stage 6 course in Year 9 or 10.
School-based apprenticeship or traineeship	Combine paid work, training and school study to earn a VET qualification and HSC credit.

If you leave school before completing the HSC, your school can nominate you for a Record of School Achievement (RoSA), which can include HSC courses you took part in but did not complete.

How is the HSC different from the ATAR?

The HSC is NESA's certificate. The ATAR is UAC's rank for university admission. They use different marks and answer different questions: your HSC marks say how you performed against set standards, and your ATAR says where you sit compared with other students.

UAC's rules are separate from NESA's. You need at least 10 units of ATAR courses, and UAC adds your scaled marks in your best 2 units of English plus your best 8 other units, scaling from your raw exam mark and moderated assessment mark rather than the aligned HSC mark on your results. NESA advises students of their ATAR eligibility on UAC's behalf, and UAC releases ATARs in December.

The eligibility rules, the aggregate and scaling are in HSC ATAR. To estimate yours, use the HSC ATAR calculator, and for the ATARs that popular NSW and ACT uni courses accepted last year, as a guide only, see the course ATAR list.

What about Life Skills and VET?

Life Skills courses are for the small percentage of students with disability, in particular an intellectual disability, for whom regular outcomes and content are not appropriate. They are reported differently: a Board Developed course with Life Skills outcomes lists the course name and units, plus a profile of the outcomes you achieved. A pattern made only of Life Skills courses is exempt from All My Own Work.

VET courses can sit inside your pattern of study. Many have mandatory work placement hours, and missing them can lead to an N determination. A Board Endorsed VET course lists all course names and units on your credential, and competencies you achieve earn an AQF VET Certificate, transcript or statement of attainment. UAC counts a Board Developed VET course toward your ATAR only if you sit its optional HSC exam.
