When we began developing this tool, a number of cities and states had developed various rating scales. We reviewed those in the process. The advantage of this tool is that it has been validated in several locales around the US, rather than just developed by a group in a particular city. Expert opinion of pedestrians who were blind and orientation and mobility specialists was compared to the tool scores. The next slide gives a brief overview of the validation process.
