How the Value Score works
The WhereNext Value Score starts at 50 (neutral) and adjusts across six dimensions: class size (−10 to +15), diversity (+0 to +10), accreditations (+0 to +10), learning support (+0 to +8), activities richness (+0 to +5), and a cost-tier adjustment that boosts cheaper schools and discounts premium-tier schools that don't justify their pricing through other dimensions.
Important: the Value Score is NOT a quality ranking. A school with strong educational outcomes can have a moderate Value Score if it sits in the premium tier; a smaller, cheaper school with good fundamentals can score higher on Value while still being a different fit for your family.
