Particular care has been taken to make the École des Ponts ParisTech website accessible to as many people as possible, regardless of their equipment setup or any disability.

This is in compliance with Article 47 of the law of February 11, 2005 which stipulates that “For equal rights and opportunities, the participation and citizenship of people with disabilities… the public online communication services of administrative departments, local authorities and the public institutions that depend on them must be accessible to people with disabilities.”

This notion of accessibility applies to all Internet users who, though without disability, may experience different access conditions, such as a low speed connection or temporary incapacity (such as a broken arm).

We assign great importance to making our content equally accessible to everyone.However, if we have failed to achieve this with any of our content, please inform us.We welcome your comments, remarks and suggestions.


Site design

As recommended:

  • We have taken great care with the ergonomics of the site to make browsing as easy as possible;
  • Stylesheets are used to separate page content from presentation, in order not to disrupt braille reading or voice synthesis;
  • As far as possible, every graphic element appearing in a webpage has a description(text alternative)

Available functions

This website includes functions to help you move around the site and to make it easy to read:keyboard shortcuts, tab key, option to adjust text size.

To remove page layout elements (colours, styles, font sizes…)
  • in Internet Explorer:click on the “Tools” tab at the top of the page, then “Internet options”.Select the “General” tab in the dialogue box and click on the “Accessibility” button at the bottom right.Check the first 2 boxes (“Ignore colors specified on webpages” and “Ignore font styles specified on webpages”), then confirm by clicking OK;
  • in Mozilla Firefox:go into the “View” tab at the top of the page, then select “Page Style” and choose “No Style”.
Browsing aids 
  • Return to homepage: on every page on the site, there is a link that takes you directly back to the homepage.
  • Breadcrumb trail: this tracks your browsing path and shows where you are in the site. The Breadcrumb Trail is located near the top of each page on the site. You can click on each item in it, so it is easy to reverse direction.
  • Site map: this gives an overview of all the site’s sections and subsections. It is available via a link at the bottom of each page.
  • Search engine: every page on the site has a link that takes you to the search engine. The result of your search displays the pages on the site that best match your search criteria.
  • Link for fast access to content: a hidden “Go to content” link allows voice synthesis users to go directly to the text area on each page.
  • There are links to the site’s main sections on every page via the fast access link at the top of the page.
  • Heading to heading browsing: the site’s pages are structured with headings and subheadings, so that voice synthesis users can, if they want, read the summary of the page.
  • Browsing by keyboard only: to move around by keyboard only, use the “up” and “down” arrows to move the scrollbar, tab to move from one link to another and the “Enter” key to open the link you are on.
