Every year, more than 10,000 Western Australian students earn an ATAR. Yet ask most Year 10 parents how the system actually works, and you'll get a look of mild panic. The Western Australian Certificate of Education is genuinely layered: course types, external exams, scaled marks, separate governing bodies — and underneath it all, a credential that far more students earn than most families realise.
If your child is heading into Year 11, or you've recently moved to WA from interstate, this guide cuts through the confusion. We'll cover every part of the WACE: what it is, what students need to earn it, how the ATAR is calculated, what external exams look like, and what pathways open up when Year 12 ends.
Key Takeaways
- In 2025, 10,265 WA students received an ATAR — a record high, up from 9,643 in 2022 (TISC, 2025).
- WACE graduation requires four things: breadth (20+ units), depth (one Year 12 course pair), literacy/numeracy (OLNA or NAPLAN equivalent), and 20 hours of community service.
- The ATAR is a national rank from 0 to 99.95, not a score — and not every WACE graduate receives one.
- General courses, VET qualifications, and school-based apprenticeships are fully legitimate WACE pathways alongside the ATAR stream.</aside>
What Is the WACE — and Who Controls It?
The Western Australian Certificate of Education (WACE) is the official qualification awarded to students who successfully complete Years 11 and 12 in WA. SCSA (School Curriculum and Standards Authority) governs the WACE, setting curriculum, moderating results, and administering external exams across all participating schools. Over 170 schools across Western Australia — government, Catholic, and independent — deliver WACE-accredited courses (SCSA, 2025).
Two things surprise families new to WA. First, the WACE and the ATAR are separate. SCSA awards the credential; TISC (Tertiary Institutions Service Centre) calculates the rank. Second, the WACE isn't just for university-bound students. It has multiple pathway types — ATAR, General, Foundation, and VET — and every qualifying student earns the same certificate regardless of which combination they chose.
The WACE was substantially reformed in 2015 to better reflect this diversity. Before the reform, the system was heavily exam-focused and largely university-oriented. The reformed WACE recognises vocational training, community service, and assessed school work alongside external exams.
What's SCSA's day-to-day role? It sets the curriculum for every approved WACE course, designs the externally set tasks (ESTs) administered mid-year, marks the November written exams, and statistically moderates school assessment results to ensure consistency across all schools. Think of it as both the rulebook and the referee.
💬 SCSA governs the WACE for all Year 11 and 12 students across more than 170 accredited WA schools, setting curriculum standards, moderating school assessment, and administering external exams for both ATAR and General courses (SCSA, 2025). The ATAR itself is a separate calculation performed by TISC — a distinction many families don't discover until deep into Year 12.
What Do Students Need to Graduate?
Earning the WACE requires meeting four requirements. Students who miss any one of them — even with strong academic marks — won't receive the credential. Here's what each means in practice.
Breadth: 20+ Units Across Years 11 and 12
Each semester of a course counts as one unit. A full-year subject equals two units. Students need at least 20 units total from Years 11 and 12, with at least 10 from Year 12. The breadth requirement also specifies minimum units from ATAR or General courses versus Foundation or VET courses.
Depth: One Year 12 Course Pair
Students must complete at least one pair of Year 12 units from the same ATAR or General course — both Semester 1 and Semester 2. This guarantees every WACE graduate has stayed with at least one senior secondary course for the full year.
Literacy and Numeracy: The OLNA
The Online Literacy and Numeracy Assessment gives students up to three attempts — at the end of Years 10, 11, and 12 — to demonstrate a minimum standard in reading, writing, and numeracy. Students who achieved Band 8 or above in Year 9 NAPLAN are automatically exempt from the relevant OLNA component. The writing component must be completed in school; reading and numeracy are online.
Is the OLNA hard? For most students it's a genuine safety net rather than a high hurdle. But students who struggle with literacy or numeracy early need to know it's a graduation requirement, not an optional extra.
Community Service: 20 Hours
20 hours of approved community service learning must be completed before the end of Year 12. Schools organise many programs, but students can also complete hours independently with a registered organisation — provided the school signs off.
💬 WACE graduation requires four distinct components: breadth (at least 20 units across Years 11 and 12), depth (at least one Year 12 course pair), literacy and numeracy demonstrated through the OLNA or NAPLAN Band 8 exemption, and 20 hours of community service (SCSA, 2025). Missing any single component prevents graduation, regardless of academic performance.

ATAR Courses vs General Courses: What's the Difference?
This is where most families get confused — and understandably so. The WACE includes several course types, and the choice between them shapes how a student is assessed, what their Year 12 looks like, and what's available at the other end.
ATAR Courses
ATAR courses are the university-focused pathway. They're academically demanding, involve an externally set task mid-year and a written final exam in November, and their results are scaled and used to calculate the ATAR. If a student wants to apply for university through the standard TISC preferences system, they'll need ATAR courses — at least four of them.
Popular ATAR choices include Maths Methods, Chemistry, Physics, Biology, English, and Specialist Maths. Each comes with a substantial curriculum set by SCSA, assessed partly by school and partly by external exam.
General Courses
General courses are school-assessed. There's no November written exam — students complete projects, assignments, portfolios, and in-class tasks marked by their school, with SCSA moderating results for consistency. General courses don't contribute to the ATAR, but they count toward WACE graduation and suit students whose goals are TAFE, an apprenticeship, or direct employment.
Many ATAR-pathway students include one or two General courses to manage Year 12 workload without affecting their ATAR aggregate.
VET Qualifications
Students can also complete nationally recognised Vocational Education and Training qualifications — Certificate II, III, or IV — as part of their WACE. VET units count toward breadth requirements, and in some cases a high-level VET qualification can contribute a small amount to the ATAR aggregate. More than half of Year 11 and 12 students now include VET units in their WACE program, up from 45% in 2016 (SCSA, 2020).
Foundation Courses
Foundation courses serve students who need additional literacy and numeracy support before General-level work. They count toward WACE breadth but don't contribute to the ATAR.
💬ATAR courses are externally examined and scaled for university entry; General courses are school-assessed without a November exam, suiting TAFE, trades, or direct employment pathways. Both count toward WACE graduation (SCSA, 2025). More than half of WA Year 11 and 12 students include VET qualifications in their WACE program, up from 45% in 2016 (SCSA, 2020).
How Is the ATAR Calculated in WA?
Here's the most common misconception: the ATAR isn't a score out of 100. It's a rank. An ATAR of 85.00 means the student performed better than 85% of their national age group — including people who left school before Year 12. In 2024, WA's median ATAR among school leavers was 83.90, and just 18 students achieved the maximum of 99.95 (TISC via Learnmate, 2024).
Getting from raw exam marks to an ATAR involves three steps.
Step 1: Raw Marks to Scaled Marks
Every ATAR course generates a raw mark — a combination of school assessment (roughly 50%) and external exam performance (roughly 50%). SCSA then applies statistical scaling to each course, adjusting results to reflect the difficulty of the subject and the academic profile of the students who chose it.
This is why subject selection has a strategic dimension. Courses with high-achieving cohorts — Specialist Maths, Chemistry, Literature — tend to scale upward. Students who perform at 75% in Specialist Maths typically receive more scaled marks than students who score 75% raw in a less selective course. Our 2025 WACE scaling guide breaks down the numbers for every major course.
Step 2: Building the Aggregate
TISC constructs the ATAR aggregate from:
- The student's best four ATAR course scaled marks (these carry full weight)
- Plus 10% of the scaled mark from a fifth ATAR or General course, or an eligible VET qualification
That's it. Six subjects studied, five counted — with the fifth counting for only a tenth of its value.
Step 3: TISC Converts Aggregate to ATAR
TISC takes aggregates from all WA students and converts them to ATAR ranks on a 0–99.95 scale, rising in 0.05 increments. A student who achieves 99.95 has outperformed every other member of their national age cohort — including tens of thousands of people who never sat Year 12 at all.
💬WA ATARs are calculated by TISC from a student's best four ATAR course scaled marks plus 10% of a fifth course or eligible VET unit (TISC, 2025). The result is a national percentile rank from 0 to 99.95 — not a score. WA's median ATAR in 2024 was 83.90, with just 18 students reaching the maximum of 99.95 (TISC via Learnmate, 2024).

Externally Set Tasks and Final Exams: How They Actually Work
ATAR course students face two external assessment moments in Year 12. Understanding both removes a lot of anxiety — and helps families plan the year properly.
The Externally Set Task (EST)
The EST is a standardised task designed by SCSA and administered mid-year, typically in Term 2. Every student studying the same ATAR course across all WA schools sits the same EST at the same time. It runs for 50 minutes under exam conditions.
Here's the key detail: the EST contributes to the school assessment component of a student's mark, not to the external exam component. It typically counts for around 15% of the total course mark. Schools administer it and submit results to SCSA, which moderates them alongside the final exam performance.
The EST is compulsory for all ATAR and General course students in Year 12. Missing it without a medical certificate or SCSA-approved absence creates a significant gap in school assessment.
The November Written Exams
The high-stakes external exams run across October and November. For most ATAR courses, the written exam accounts for approximately 50% of the final course mark, with school assessment (including the EST) making up the other 50%.
SCSA uses statistical moderation to check that each school's internal marks are consistent with how their students performed on the external exam. This prevents grade inflation and ensures students from different schools are compared fairly.
Exam dates are published by SCSA well in advance — usually by Term 2 of the exam year. For exact dates, check our 2025 WACE exam timetable.
💬ATAR course students sit two external assessments: the Externally Set Task (EST) in Term 2, contributing approximately 15% of the school assessment component, and the written external exam in October–November, which typically accounts for 50% of the final course mark (SCSA, 2025). Both are administered under SCSA oversight, with statistical moderation applied to school results.
What Pathways Open Up After the WACE?
The WACE isn't only a door to university. It's three doors, and students who understand all of them make better subject choices in Year 10.
WA's Year 10 to Year 12 retention rate sits at 74.4% — below the national average of 79.9% (ACARA, 2024). The gap is partly explained by WA's strong mining and resources sector, which offers well-paid trade and apprenticeship pathways that don't require a full Year 12 completion. For students who do complete the WACE, the options are genuinely broad.
University via ATAR
Students with an ATAR apply to WA universities through TISC's preferences system. Each course at each institution has a published cut-off ATAR — though these change each year based on demand. WA universities include UWA, Curtin, Murdoch, ECU, and Notre Dame. Most also offer direct-entry or enabling programs for mature-age students or those with strong VET qualifications who don't have a competitive ATAR.
TISC applies bonus points in several categories: students from low-ATAR-producing schools, rural and remote students, and those completing approved enrichment programs. These adjustments can be meaningful for borderline applicants.
TAFE and Vocational Pathways
WA's TAFE system — delivered through North Metro TAFE, South Metro TAFE, Central Regional TAFE, and others — is a direct route to skilled employment, often faster than a university degree. Students who completed Certificate II or III units as part of their WACE frequently have credit toward TAFE qualifications.
TAFE also feeds back into university: many institutions accept TAFE diplomas for entry into degree programs with advanced standing, meaning students can enter second year of a degree with a diploma.
Apprenticeships and the Workplace
School-Based Apprenticeships and Traineeships (SBATs) allow students to begin a nationally recognised qualification — and earn a wage — while still enrolled in Years 11 and 12. Units completed through an SBAT count toward WACE breadth requirements. Trade pathways include construction, electrical, automotive, plumbing, and allied health among many others.
💬After the WACE, WA students can pursue university entry via ATAR through TISC's preferences system, TAFE and vocational training (often with credit from in-school VET units), or direct employment through School-Based Apprenticeships and Traineeships (TISC, 2025; SCSA, 2025). WA's Year 12 retention rate of 74.4% sits below the 79.9% national average, partly reflecting the strength of WA's trade and resources sector (ACARA, 2024).
Which Subjects Should Your Child Choose?
Subject selection in Year 10 locks in the shape of Years 11 and 12. Get it right and the next two years feel purposeful; get it wrong and students spend Year 11 trying to drop subjects or squeeze into already-full courses.
A few principles that work in practice:
Match the pathway first. If university is the goal, four ATAR courses are the minimum. Ideally, at least one should be a maths or science course with a strong scaling history, since university programs in science, engineering, and medicine typically expect it.
Don't choose a subject purely for scaling. Specialist Maths scales very well, but a student who finds it genuinely hard will score lower than in a course that suits them. A lower raw mark in a high-scaling course doesn't automatically beat a high raw mark in a moderate-scaling course.
Think in prerequisite clusters. Engineering and computer science expect Maths Methods. Medicine and health science expect Chemistry and Biology. Commerce is flexible but rewards Maths Methods. Check the prerequisites for intended degrees before finalising choices — not after.
Balance ATAR and General courses. Many high-performing ATAR students include one General course to maintain workload balance without affecting their ATAR aggregate.

Frequently Asked Questions
What is the minimum ATAR for university in WA?
There's no single minimum — it depends on the specific program and institution. Some degrees at WA regional universities accept students with ATARs in the 50s; competitive programs at UWA (Medicine, Law) typically require 90 or above. TISC publishes the previous year's cut-off ATARs for every course at every WA institution, which gives the clearest guide to realistic targets for your child's intended field.

Can you get the WACE without receiving an ATAR?
Yes — and many students do. Students who complete General or Foundation courses without any ATAR courses still graduate with the WACE, provided they meet the breadth, depth, literacy, numeracy, and community service requirements. The ATAR is only calculated for students who study ATAR courses and want to use it for university entry. In 2025, 10,265 WA students received an ATAR (TISC, 2025) — but the total WACE graduate cohort is considerably larger.
What happens if a student doesn't pass the OLNA?
Students have three attempts: at the end of Years 10, 11, and 12. A student who doesn't achieve the standard before completing Year 12 won't receive the WACE, even if their academic results are otherwise strong. Schools are required to identify at-risk students early and provide literacy and numeracy support. In some circumstances, students may receive a Statement of Student Achievement recognising what they did complete rather than the full WACE credential.
How does course scaling affect subject choice?
Scaling adjusts raw marks based on the academic profile of a course's cohort. A student who performs at 75% raw in Specialist Maths typically receives more scaled marks than a student who scores 75% raw in a less selective course — because Specialist Maths is disproportionately chosen by high-achieving students, pushing its scaling upward. That said, never choose a course purely for scaling. Underperforming in a high-scaling course generally results in a lower scaled mark than performing well in a well-suited moderate-scaling course. For a full data breakdown, see our 2025 WACE scaling guide.
Is the WACE recognised outside Western Australia?
Yes. The WACE is nationally recognised, and ATARs from WA are accepted by universities across Australia. TISC coordinates with interstate tertiary admissions bodies — UAC in NSW, VTAC in Victoria, SATAC in SA, QTAC in Queensland — so WA students can apply interstate using their WA ATAR without conversion.
Conclusion
The WACE rewards students who understand it before they're in the middle of it. Once you know the four graduation requirements, the difference between ATAR and General courses, and how the ATAR is built from scaled marks, Year 11 and 12 become a manageable — and strategic — experience rather than a stressful mystery.
The most valuable thing a family can do right now: decide the pathway first. University, TAFE, or trades — that single decision shapes every subject choice, every exam to prepare for, and every resource worth investing in.
Start planning in Year 10, well before the pressure of Year 11 kicks in.
