About this ranking
About this data
ScanGov scans the homepage of each county site on our county list in Connecticut. Scores come from the checks in the ScanGov standards. Sites were scanned between 10/27/2026 and 10/28/2026. 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. 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.
