Tk20 by Watermark


  • General Information & Tips

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

    Please make sure your web browsers are up-to-date for the best Tk20 performance.

    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.

    Most College of Education courses also list Tk20 as a required text in the University Bookstore.

    Tk20 is secure and confidential. No one will have access to your files except you, your instructors, and advisors.

  • Student Logins

    To log in, use your iLearn or Tech student email as the username (without and password. 

    Students must change their Tk20 passwords through the ITS website. Changing your password for Tk20 will also change the passwords for your iLearn and email accounts. Follow the Self-Help Guide or contact the ITS Help Desk at 931.372.3975 for further assistance.

  • Account Information


    All students, regardless of affiliated major and college, enrolled in courses requiring Tk20 must purchase an account and submit the appropriate coursework.

    All types of licensure students are required to purchase Tk20. This includes, but is not limited to, transitional/job-embedded, add-on endorsement, CTE, INSL, and any other initial or advanced licensure programs.

    Failure to purchase Tk20 can result in a zero for Tk20 assignments and/or final course grade reduced a full letter.

    There are two locations to purchase your Tk20 account:

    • Tk20: $103.00. Click on the link in the bottom left hand side of the page that states, “Click here to purchase or register your student account.”
    • University Bookstore, University Center: $142.85. Financial aid will pay for the subscription like a textbook when purchased through the bookstore. After purchasing the Student Access Kit, you will register the account code through the Tk20 Login page. Click on the link in the bottom left hand side of the page that states, “Click here to purchase or register your student account.”


    Tk20 allows for 2-3 business days to activate the account after purchase.

    Students cannot log in until the account is activated.

    You will purchase Tk20 only once. The account will be active for seven (7) years from the date of activation.


    Tk20 will offer refunds for student subscriptions per the following policy:

    • For accounts completely unused, and a refund is requested within 30 days of purchase: full refund.
    • No refunds will be issued for used accounts and/or after 30 days of purchase under any condition.

    If you feel that you are eligible for a refund, please complete the online Tk20 Refund Request.


    Student accounts can be transferred between universities with Tk20 contracts. For example, if you purchase Tk20 at Tennessee Tech and then transfer to another university using Tk20, you can also transfer your Tk20 subscription.

    Email the Unit Administrator at In the email, include your name, T-number, username, and the school you want to transfer the account to or from.

    If you are transferring an account to Tennessee Tech, also list your student ID# and username at that school.

    Your account can only be active at one institution at a time.

    Your original expiration date continues to apply.

    Only the account activation transfers, not data. For technical reasons Tk20 cannot move the contents of your account from one Tk20 system to another. Practically, this means that once you move institutions you should consider the Tk20 account at your old institution to be locked out and unavailable.
