The University of Pennsylvania website is frequented by a diverse group of people from around the globe. Some of our users have visual or motor skill impairments and utilize assistive technologies such as screen readers and text-only browsers; others view our pages using outmoded technologies and slow connection speeds. It is important that website creators be cognizant of these limitations and strive to make their websites accessible to the greatest number of people. As such, Penn websites should be compliant with Section 508 of the Rehabilitation Act of 1973
