Elite independent schools (Geelong Grammar, Sydney Grammar, Scotch College, Methodist Ladies' College): $42,000-$55,000/year for Year 12. Mid-tier independents: $25,000-$38,000/year. Catholic systemic schools: $4,000-$10,000/year. Boarding adds $25,000-$45,000 on top. Year 7-9 fees typically 30-40% lower than Year 12. Total K-12 cost: $400,000-$650,000 for elite schools, $40,000-$120,000 for Catholic systemic. Add $5,000-$15,000/year for uniforms, IT, camps, music tuition.

Elite schools (Scotch, Geelong Grammar, Sydney Grammar): apply at birth or before age 2 for Year 7 entry. Waiting lists at top schools are 1,000+ children. Mid-tier independents: apply 2-4 years before entry year. Catholic systemic: 12-24 months before entry year. Most competitive entry points: Reception (limited places open most spots), Year 7 (start of secondary, biggest intake), Year 11 (VCE/HSC start). Apply to 4-8 schools simultaneously to maximise options.

ICSEA (Index of Community Socio-Educational Advantage) measures the socio-economic background of a school's community. Average is 1000. Elite private schools typically score 1180-1230. ICSEA correlates strongly with academic outcomes — but it measures family advantage, not school teaching quality. To assess teaching quality, look at "value-added" data (how much the school improves students above their starting point) — Education Department websites publish this. A school with ICSEA 1200 should produce strong results; a school with ICSEA 1100 producing strong results is doing more impressive teaching.

Top elite schools: 5-15 academic scholarships per year for Year 7 entry, 200-500 applicants. Highly competitive — typically requires top 1% performance on ASCAS test plus interview. Mid-tier schools: easier scholarships available, often 30-50% fee reduction. Music scholarships at most schools: less competitive than academic, requires 5+ years instrument experience and grade 6-7 AMEB level. Sport scholarships: rare, mostly for boarding. Financial assistance (means-tested): 5-30% of places at most schools. Apply to 3-5 schools simultaneously to maximise chances.

Catholic systemic schools (parish-funded): $4,000-$10,000/year, generally similar academic outcomes to mid-tier independents, religious instruction (Catholic but increasingly inclusive), community-focused, lower socio-economic mix. Independent schools (privately governed): $25,000-$55,000/year, broader extracurricular options, smaller classes, more international students, stronger university preparation, higher ATAR outcomes. Catholic congregational schools (Loreto, Xavier, Mary MacKillop College, etc.) bridge the two — Catholic ethos but independent governance, fees $20,000-$35,000. Many families choose Catholic for primary, independent for secondary.
