The accessibility review of the Web Accessibility Observatory is performed by an automated methodology developed specifically for this observatory. This methodology took into account only 20 accessibility checks. Each one of them consisted of several automatic verification tests. In addition, this methodology used special metrics that include some checks that usually are manually reviewed.

In July 2015 was adopted the first methodology using the standard UNE 139803:2012 (WCAG 2.0) (available abstract in English), by the Websites working group of the general administration of the state and has been endorsed by the working group of the "Observatorio, Indicadores y Medidas" of the "Comité Sectorial de Administración Electrónica" (regional and local governments).
