What is Tk20?

Tk20 is a comprehensive online data management system that allows students to be active online participants in multiple areas throughout their college instruction, field experiences, and sharing of assessment data.  Tk20 stands for “Technology in Kindergarten through Age 20”.  It is required for all students working towards any credential that prepares them to work in P-12 schools.

  • Students can create electronic portfolios for documenting their work and present it to faculty and prospective employers.
  • Keep a completely documented record of student work in schools, including field experience and internships.
  • Students can fill out application forms and surveys online

Who should I contact if I lose the link to my student’s Tk20 page?

You should contact your intern’s university supervisor and request that he/she resend you the link to Tk20.

What are some of the best practices for usingTk20?

  • Never click on the link to Tk20 that is in the email you receive from  Doing so can result in Tk20 being opened multiple times.  ALWAYS COPY AND PASTE THE SECOND LINK in the email you receive!
  • Use the most recent versions of the recommended internet browsers.
  • DO NOT use the browser back button. Instead, navigate using the tabs and menus within Tk20.
    • Using the browser Back button may result in a loss of important information that was not saved.
  • DO NOT sign into Tk20 in multiple tabs or windows.
  • Wait until a page fully loads before taking a subsequent action. (Look for the spinning circle!)
  • Always log out of Tk20.  If you simply close your browser, the next time you try to access Tk20, you may receive the OOPS! Message as Tk20 sees that your account is still open from the previous session.
