Tk20 by Watermark

Mentor teachers are also known as "Cooperating Teachers" in the Tk20 system.

Tk20 recommends using the web browser Google Chrome if possible. Internet Explorer/Microsoft Edge may not save information correctly.

Avoid using your browser's "Back" button while working in Tk20. Use Tk20's buttons (Save, Cancel, etc.), tabs, and side menu items.

Do not open Tk20 in more than one browser/browser tab at a time. The system may not save information correctly.

Save your work often! The evaluation forms "time out" after long periods on one page, even if you are entering information.

Tk20 accounts are created for all mentor teachers. You do not need to create or purchase an account.

The account's username and initial password is the email address provided to Tennessee Tech's Office of Teacher Education (residency, student teaching) or faculty supervisors (practicum).

Passwords are reset to email addresses on August 1st and January 2nd each year.

Mentor teachers will be prompted to change their password the first time logging into Tk20 and after each password reset date.

If you click "Save"  while working on a form, Tk20 will take you to the student's binder and split screen. Look for the form links on the right side of the screen to click on and resume working.
