Description

Under the EU Web Accessibility Directive (2016/2102), Estonia's Consumer Protection and Technical Regulatory Authority (TTJA) ran statutory web-accessibility monitoring from 2022 to 2024, testing 381 website instances (235 unique domains) and 23 mobile-app instances (15 unique apps) against EN 301 549 (WCAG 2.1 AA). External contractor Trinidad Wiseman OU supported the work; automated scanning used Siteimprove in 2022 and the free tool Salvia from 2023 onward.
Simplified-monitoring average scores held near-steady across the growing sample (102 sites in 2022, 116 in 2023 and 2024): 77%, 79% and 78% respectively, with the highest score rising from 93% to 100% to 97%. In-depth monitoring — manual review of 15–16 web domains each year — is more telling: the average non-conformity rate fell from 18.9% in 2022 to 16.43% in 2023 and 12.44% in 2024, a 6.46-percentage-point improvement over three years. Mobile-app non-conformity also improved, by 5.08 percentage points.
The report is candid about its limits: the 2022 results used a different scanning tool and are not directly comparable to 2023–24, and a 100% simplified-monitoring score (achieved only once, by Tallinn's Medical Centre website in 2023) means no deficiency was found under the tested automated rules — not that the site is fully accessible to all users.
