Raising the Floor is " an international coalition of individuals and organizations working to ensure that the Internet is accessible to people experiencing accessibility or literacy problems, even if they have very limited or no financial resources. The goal is to ensure that individuals who need special interfaces are as free and able as everyone else to use the new and emerging Internet tools and resources to live more independently and productively, and to achieve their life's goals".
The group works to put "the Web within reach of all those with
disability, literacy, or aging related barriers,
regardless of their economic status".
