The XXI Century society has developed a drive for Information and the Web, as one of the extremely important technologies of our times, represents the main channel to access it. As a result of this, one can perceive that the Web, and the inherent websites, must be accessible to all, in order to maintain the imperative social equality. Despite the legal requirements to the Portuguese Web content accessibility levels, in effect since 1999, the existent studies that focused on assessing those same levels of accessibility reported that the Portuguese websites, in their majority, were not compliant with the existent standards. In mid-2007 we started, within our research group and in partnership with both UMIC – Knowledge Society Agency and APDSI – Association for the Promotion and Development of the Information Society, a Web accessibility barometer. The goal of this barometer has been assessing the accessibility levels of the Portuguese websites, creating recommendations - for both the organiza- tions and the civil society - towards the improvement of the referred websites, and publicly presenting the achieved results. One of the Portuguese enterprises that is adopting the accessibility standards into its public procurement platform anoGov is ANO. This company established a research project alongside UTAD University in order to achieve technical know-how and good practices that al- lowed them to develop accessible and usable Web content.

Given that 10% of the European citizens present some sort of disability or incapaci- ty, it is important that European websites present themselves accessible to all [10-12]. Accessibility can be defined as the ability of a disabled or incapacitated person to access services or products or execute a given task in an equal manner as one without any impairment. In the ICT domain, one can characterize accessibility as the exis- tence of interfaces that can be used and perceived by all the users, in an equal manner [13-15].
