For the 2020-2021 academic year, Iowa State is eliminating the delivery fee that has been linked to XW-labeled courses and sections. We are also eliminating the XW designation; all online courses will be labeled WWW.

To find a WWW course on the schedule of classes:
  1. Go to the Schedule of Classes
  2. Click on “Toggle Advance Search”
  3. Select “Online” under Course Type

If you are a distance student and feel that your tuition has been calculated incorrectly based on the above changes for the academic year, please email

Please do not hesitate to contact the Office of the Registrar if you have any questions about these changes.
