Questions to Ask Each School Type

For All Schools

1. What is your approach to student wellbeing?
2. How do you differentiate learning?
3. What support services are available?
4. How do you measure student progress?
5. What are pathways beyond Year 12?

Public School Specific

• What programs distinguish this school?
• How active is the P&C?
• What are voluntary contribution expectations?

Catholic School Specific

• How is faith integrated into learning?
• What are requirements for non-Catholic families?
• How does the school live its mission?

Independent School Specific

• What is the school's educational philosophy?

The Bottom Line: Value for Investment

Research consistently shows that school sector matters less than school quality and fit. The best school for your child is one that:

• Aligns with your family values and budget
• Meets your child's learning needs
• Provides a safe, supportive environment
• Offers appropriate academic challenge
• Prepares students for their chosen pathway

Remember: excellent education happens across all sectors. Focus on finding the right fit rather than assuming one sector is inherently superior. Visit schools, talk to current families, and trust your instincts about where your child will thrive.
