http://dallas.gradespeed.net/pc/ is not a recognized GradeSpeed address.

The URL you have accessed is no longer valid. Please access GradeSpeed using the address provided by your school district. Campusware is committed to protecting the privacy of our users, especially those users who utilize our hosting service. In the past, users who went to an older URL such as “gradebook3.gradespeed.net” were redirected to a generic site. This generic site would not allow a user to log into an incorrect school, but would allow a user to view a list of districts and campuses that were contained within Campusware’s hosting system. Users are now required to access GradeSpeed through the district-specific website address provided by the school office.

Example: "http://district_name.gradespeed.net"

If you are not sure what address to go to, please contact your school’s office and they will assist you.
