Web accessibility checker


The OAW Tracker allows to carry out web accessibility reports of Spanish public portals. This tool allows generating automatic reports from the almost 100 checks implemented in the platform, as well as providing recommendations on how to solve the problems detected.


The accessibility review of the OAW studies is carried out using an automatic methodology based on the standard UNE 139803:2012 (WCAG 2.0).

Use cases:

The OAW tracker analyzes twice a year more than 700 portals, which is the official analysis of approximately 25,000 pages. The analysis of more than 60,000 pages annually is requested through the online diagnostic service.


The Government of Argentina is testing the tool in order to personalize it and use it to monitor compliance with the accessibility requirements with respect to its Law No. 26.653 on "Accessibility of Web Page Information".
