Browser Settings when working in Blackboard, Canvas, D2L, Sakai, or Moodle

Your Institution has incorporated Tk20, Inc. into its Learning Management System (LMS) (e.g., Blackboard, Canvas, Angel, Moodle, etc.). Tk20 is assessment software which assists your College or University in measuring student learning. When you log into your LMS account, to submit an assignment (students) or evaluate a student submission (faculty), you are accessing Tk20 coursework through the LMS. If you are experiencing issues accessing or submitting your work, please try the following:

Update Your Internet Browser

Are you using the most current version of an internet browser? (e.g., current version of Google Chrome, Mozilla Firefox, Safari, Internet Explorer). You may not be able to upload a document, or even submit the assignment, due to using an outdated internet browser. While it works well with most browsers, Tk20 recommends and fully supports the latest two versions of the following browsers for optimal use:

Google Chrome
Mozilla Firefox*
Microsoft Internet Explorer

*We recommend using Mozilla Firefox browser if you are working on a Linux platform.
