What each check means

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.
Heading elements appear in a sequentially-descending order. Page headings follow a logical order without skipping levels. Keyboard users cannot efficiently navigate your site.
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.
Document has a main landmark. The page has exactly one main content area so screen readers can navigate to it. Screen reader users cannot skip directly to main content.
[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 data

ScanGov scans the homepage of each county government site on our county list in Illinois. Scores come from the checks listed on standards.scangov.org. Sites were scanned between 8/24/2026 and 9/18/2026; each site's report shows its own scan date. A site counts as fully scanned when its homepage returned successfully and sent the scanner its page content. Averages, grade shares, failure rates, and ranks use fully scanned sites only. We weren't able to fully scan 10 sites because they did not respond, blocked the scanner, or returned no page content. They appear in the table without grades, each with its scan status, and are left out of every figure. Grades follow the ScanGov grade scale, and rank follows the ScanGov ranking method. The full dataset, including every county's raw results, is published in the ScanGov data repository.
