How we decide
- A school only competes where we measured it. Missing data never wins.
- A group with fewer than 8 measured schools gets no award.
- One winner is named only when one school stands alone at the top. Tied schools share the award.
- If more than 40% of a group would share it, no award is given.
- No parent-rated award yet, as we hold no parent reviews.
- Scores come from the Houseroom Index method.
