Compulsory School Age WA: When Education Is Required and When It Ends

Parents in Western Australia sometimes assume their child is not yet old enough to need formal enrolment, or that they can remove their teenager because they are "almost finished" with school. Both assumptions carry legal risk.

WA's compulsory education rules are defined precisely in the School Education Act 1999. Understanding the exact boundaries — when the obligation starts, when it ends, and what satisfies it — is essential before making any decision to withdraw from school.

When Compulsory Education Begins

In Western Australia, compulsory education begins at the start of the school year in which a child reaches 5 years and 6 months.

In practical terms: if your child turns 5 years and 6 months at any point during a calendar year, the obligation begins on the first day of that school year in Term 1.

This is earlier than many parents expect. A child who turns 5 in August, for example, does not need to start school that February — but by the following February (the start of the next school year), when they will be 5 years and 6 months partway through the year, they are compulsory school age from the beginning of that year.

Children younger than this are not subject to the compulsory education requirement. Early childhood education — kindy and pre-primary — is available but not compulsory under WA law.

When Compulsory Education Ends

The obligation to be in education ends at whichever of these three milestones occurs first:

1. The end of the year in which the child turns 17 years and 6 months. A child who turns 17 in August is subject to compulsory education through the end of that calendar year.

2. The end of the year in which the child reaches 18. If the child turns 18 during a school year, compulsory education extends to the end of that year.

3. The end of the year in which the child completes secondary education. A child who completes Year 12 is no longer subject to compulsory education regardless of age.

For most families, milestone 1 is the relevant one. A 17-year-old who turns 17 years and 6 months before the end of the year finishes their compulsory education at the end of that year and is free to leave without any formal education arrangement in the following year.

What Satisfies the Compulsory Education Requirement

The obligation is to be in education — not specifically to be enrolled in a school. WA law recognises several ways to satisfy the compulsory education requirement:

Enrolment and attendance at a government school. The default pathway.

Enrolment and attendance at an approved non-government school. This includes Catholic systemic schools, independent Catholic schools, and other non-government registered schools.

Registered home education. A parent or legal guardian who is approved by the Education Directorate to provide home education satisfies the compulsory education requirement. The child is not required to attend school.

Enrolment in an approved course or training. In some circumstances, vocational training or other approved programs may satisfy the requirement for older students.

Home education is therefore not a way around the compulsory education requirement — it is a way of meeting it through a different lawful pathway.

The Gap Problem: Between Withdrawal and Registration

The compulsory age rules create a specific risk for families who withdraw from school before home education registration is approved.

If your child is compulsory school age, they must be enrolled somewhere or registered for home education. When they cease school attendance, the clock starts. WA law gives you 14 days from the last day of attendance to submit your home education registration application.

During those 14 days, your child is not yet registered for home education but is also no longer at school. This gap is legally permitted — the Act recognises that there is a processing period — provided you submit the registration application within the 14-day window.

If you do not submit within 14 days, your child enters a period where they are compulsory school age, not enrolled in school, and not registered for home education. This is where truancy protocols are triggered and where families start receiving contact from the school or ERO.

Kindy and Pre-Primary: Not Compulsory

Western Australia funds kindy and pre-primary places, but attendance is not legally compulsory. You are not required to enrol your child in kindy or pre-primary, and there is no legal consequence for choosing not to.

The compulsory obligation begins in the year your child reaches 5 years and 6 months — which in most cases corresponds to Year 1, not kindy or pre-primary.

Families who prefer to begin home education from the start rather than enrolling at all can do so, but should confirm with their ERO whether a registration application is needed before formal compulsory age is reached. Some EROs process pre-compulsory home education applications; others do not.

Older Students: Finishing School Early

If your 16 or 17-year-old wants to leave school and you are considering home education as a transition pathway, the compulsory age rules are directly relevant.

A 16-year-old is still in the compulsory age range and must either be at school or registered for home education. They cannot simply leave without a compliant arrangement in place.

A 17-year-old who has passed the 17 years and 6 months threshold before the end of the year and has not completed Year 12 is in a transitional position. Once the year ends, the obligation ends. Before that point, they remain subject to the compulsory education requirement.

Some families use home education registration for the final year or part-year as a structured way to exit school and pursue other pathways (VET, employment, independent study) before formal compulsory age ends.

Putting It Together

The compulsory school age rules in WA are precise but not complicated once you understand the framework. Education is mandatory from the start of the year a child reaches 5 years and 6 months, until whichever of the three exit conditions is met first. Home education is a lawful way to satisfy that obligation, provided registration is in place.

The gap between withdrawal and registration is the single most common point of failure. The 14-day window is real and must be observed.
