Best Catholic schools in Western Australia

27 schools assessed independently — no paid rankings.

Choosing a school is one of the biggest decisions an Australian family makes, and the private sector alone runs to hundreds of schools that differ enormously in size, character, governance and strength — from small regional colleges to century-old metropolitan institutions, each with its own account of what makes it the right choice. A prospectus or an open day rarely settles how one school actually compares with another on the things that matter most to a family.

Schools360 scores every one of them against five questions that matter to a parent choosing a school. How well does the school perform academically? How well will the school look after my child's wellbeing and individual needs? Does the school offer extensive learning opportunities for my child? Does the school offer a great environment for my child to realise their full potential? How well is the school run? The combined result places each school in one of five tiers: Elite, Distinguished, Leading, Trusted, Highly Capable. Every tier name describes a genuine strength; Schools360 publishes no failing grade.

That assessment is independent and built entirely from public information — government data, academic results, school websites, strategic plans, annual reports, teacher reviews, alumni pathways and media reporting — never a form a school fills in about itself. Any content a school does supply directly is always shown separately on its profile and clearly labelled as the school's own words, not part of the assessment.

Catholic schools are one of the two major strands of Australian private education alongside the independent sector, enrolling around one in five Australian students nationally. Many trace their identity to a founding religious order — Loreto, Mercy, Presentation, Marist and Jesuit traditions among them — and combine that heritage with a pastoral, community-oriented approach to schooling that shapes everything from parish primaries to the large systemic colleges ranked below.

This page assessed 27 Catholic schools in Western Australia. The top 10 are ranked below; the rest are also assessed and listed beneath, without an individual rank. Read the full methodology.
