How to Purchase and Log into Tk20

Use the buttons below to purchase your Tk20 account or to login to Tk20.

Click to Purchase your Tk20 Account

Students must purchase Tk20 before logging in. If you attempt to log in without purchasing, you will get an error message. Once purchased through the above link, it may take between 24 and 72 hours to activate. Please plan for this delay. If you need to purchase Tk20 through the bookstore, they will give you an activate code and you can use it by going to the same purchase link.  If you have questions about Tk20 accounts, check the Tk20 FAQs.

Click to Log into Tk20

Use this link to log into Tk20 through CSU's Single Sign On (SSO) service (OneCSU). This page will use your OneCSU username in the following format and CSU password.

For non SSO users, the legacy Tk20 login page can still be found at Your Tk20 username for this page is LastName_FirstName# (everything in front of the @ of your CSU email address).

Tk20 FAQ

Q: How do I get a Tk20 account?

A: If purchasing an account with a credit card (cheapest, easiest way), click on the Click to Purchase your Tk20 Account button at the top of this page. 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 above (Click to Log into Tk20).

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 sign on 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.

If you are have just been accepted or transferred and not yet registered for classes, you will not be able to immediately use Tk20.

Q: What is Tk20?

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
