Frequently Asked Questions
What is a hidden gem school?
A hidden gem is a school whose NAPLAN performance significantly outperforms what its suburb's house prices would predict. A school qualifies when its Gem Score — the gap between its state NAPLAN percentile and its state house price percentile — is 30 or higher.
How is the Gem Score calculated?
The Gem Score equals the school's NAPLAN Combined Percentile minus the suburb's House Price Percentile, both calculated within the same state. A Gem Score of +30 or higher qualifies as a hidden gem.
How much can families save?
Hidden gem families enjoy a median suburb house price of $600,000, compared to $1,310,000 for non-gem schools with similar NAPLAN scores — a median saving of $710,000.
What data sources are used?
School performance data comes from ACARA MySchool (2025 NAPLAN results). Suburb property data is sourced from Domain.com.au (median house prices). The dataset covers 7,606 schools across all 8 states and territories.
Does a high Gem Score mean a school is good?
A high Gem Score means the school delivers strong NAPLAN results relative to its suburb's affordability — it's a measure of value, not an absolute quality ranking.
