Tk20 FAQ

Q: How do I get a Tk20 account?

A: If purchasing an account with a credit card (cheapest, easiest way), go to the TK20 page and click on the purchasing button.  On the new page, select the option that says "I need to purchase my 7 year Tk20 account."  When purchasing this way, the price will be $139.00 + $3.00 processing fee. Financial aid may pay for the account if purchased through the Campus Book Store, though the price will vary.

Q: I just purchased Tk20 and get an "oops" error when I try to log in. What's wrong?

A: After purchasing a TK20 subscription, it can take up to 72 hours to activate on our server (though it usually takes just 24 hours).  Wait a day or two and try again.

Q: After I've purchased TK20 and waited for my account to be activated, how do I log in?

A: You'll log in through CSU's Single Sign On (SSO) service (OneCSU).  You can find a button to autolog into TK20 on the Tk20 page.

Q: What is my Tk20 username?

A: Tk20 uses CSU's single sign-on service, so if you are logging onto Tk20 through CSU's signon page, your username is the same as your other CSU logins, which is usually -- It's your CSU email address with an "ad1" in it, not your normal CSU email address. 

Q: I am trying to login but getting an error message that says my username or password is incorrect.  What's wrong?

A: First, you may be trying to use the wrong username.  Make sure you are using as the username -- not your normal CSU email address.  Second, if you are a new student (new to CSU, new to teacher education, new to an education major, etc.) it can take up to two weeks after you've been enrolled in education courses for your account to setup.  If you are have just been accepted or transfered and not yet registered for classes, you will not be able to immediately use Tk20.

Q: What is Tk20?

A: Tk20 is a repository for university data that are collected for various purposes; such as, demonstrating the quality of our academic programs, improving teaching and learning, and compiling data for national, state, and local reporting.  Tk20 facilitates the performance assessment and field placement processes and provides a tool for candidates to document their development, competencies, accomplishments, and progression through their preparation program.

Q: What is the primary role of a student in Tk20?

A: Students are key to data collection in Tk20; without students, there would be no data! Students primarily will use Tk20 to submit their work for assessment, but can also build portfolios, field experience binders, and presentation portfolios to share with others.

Q: I am no longer a student at CSU, but want to access my Tk20 account.  How can I do this?

A: First, contact the administrator (using the information at the bottom of this page) and have a legacy user account setup. Once your account is setup, you can log on using the page at
