International Baccalaureate in Tewantin, QLD

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.

Research is mixed. Australian Productivity Commission analysis shows private schools deliver 5-8 ATAR points improvement over government schools on average, but much of this is explained by socio-economic background, not teaching quality. Top selective government schools (NSW: Sydney Boys/Girls High, James Ruse; VIC: Melbourne High, Mac.Robertson) consistently outperform top private schools at zero cost. Private school benefits are real (network, extracurriculars, smaller classes, pastoral care) but financial cost is significant, $500,000 invested at age 5 instead would be worth $1.5M+ at age 18 for university and house deposit help.

Visit open days at 5-8 schools matching your geographic and budget criteria. Talk to current parents (often more revealing than school marketing). Ask schools for: median ATAR (or NAPLAN value-added data for primary), retention rate from Year 7 to 12, specific strengths in your child's areas of interest, pastoral care approach, school culture. Match school strengths to your child, academic powerhouse for high achievers, more pastoral schools for sensitive children, sport-focused for athletic kids, music-strong for musicians. Don't just pick the highest-fee school.
