What each check means
- Links have a discernible name. Links have unique, descriptive text so users know where they go. Screen reader users cannot identify or interact with elements.
- Elements with an ARIA [role] that require children to contain a specific [role] have all required children. Interactive groups contain all the child elements they need to work correctly. Screen readers cannot navigate grouped elements like menus or lists.
- Heading elements appear in a sequentially-descending order. Page headings follow a logical order without skipping levels. Keyboard users cannot efficiently navigate your site.
- Background and foreground colors have a sufficient contrast ratio. Text and background colors meet minimum contrast ratios. Users with low vision cannot read your text.
- [aria-hidden="true"] elements do not contain focusable descendents. Interactive elements are not hidden from screen reader users. Keyboard users can focus elements that screen readers cannot announce.

About this ranking
About this data
ScanGov scans the homepage of each county site on our county list in California. Scores come from the checks in the ScanGov standards. Sites were scanned between 9/30/2026 and 11/6/2026. Each site's report shows its own scan date. A site counts as fully scanned when its homepage loaded and sent us its page content. Averages, grade shares, failure rates, and ranks use fully scanned sites only. We could not fully scan 17 sites. They did not respond, blocked the scanner, or sent no page content. They appear in the table without grades, with their scan status, and are left out of every figure. Grades follow the ScanGov grade scale. Rank follows the ScanGov ranking method. The full dataset, with every county's raw results, is in the ScanGov data repository.
