Important context

QERIS results are based on automated testing of a defined sample of each institution's public pages, following a published, versioned methodology. Automated testing detects only a subset of accessibility issues and does not replace expert human evaluation or testing with users with disabilities. The absence of detected errors does not mean a site is fully accessible or conformant; scores reflect performance on automatically detectable measures only.
