Niche grades and rankings are based on a variety of data. Each grade has a specific methodology - while these methodologies can include other grades as factors, they do not always overlap and as such, grades are not always affected by one another. The Overall Grade has its own specific methodology, rather than being an average of the other grades shown on your report card. Beneath the Overall Grade on your school's report card, there are links to the Niche grade methodologies and data sources pages.
