Download ExtensionWhat this shows: How the same percentile rank (e.g., top 5% = 95th percentile) has been getting higher scores over time, indicating score inflation.
Example: If the 95th percentile was 8.22 in 2010 but is 8.65 in 2025, that's a clear sign of inflation - the "top tier" threshold has moved up.
