Are frames accessible?
Frames are not in and of themselves inaccessible. Keyboard users and assistive technology users are able to navigate among the various frames that comprise a web page. In order to facilitate navigation, each frame must be assigned a title (using the “title” attribute) that clearly communicates the function of the frame (e.g., “Navigation” or “Content”). Also, screen reader users should be provided with clear instructions on how and where to locate content within the frameset.
