This data system is required for students graduating in the fall 2013 semester and afterward, unless you are graduating in the fall 2013 semester and all of your certification tests have been completed. A Tk20 account is not  required  for speech-language pathology students.

You can now purchase an account through the Brooklyn College Web Central portal under Academics.

Important Note

When you are on the Tk20 page where you enter your contact and credit card information, do not enter your student ID number where it asks for your ID number. Instead, enter the same exact user name / Web Central ID that you use to login to BC Web Central. For example, if you sign in to BC Web Central as “JDoe” you will use “JDoe” for your student ID "number" on the Tk20 purchase page. If you do not enter the correct ID, your account verification will be delayed.

After your account is activated, you will access Tk20 through the same place: Web Central/ Academics tab/Tk20. You will be automatically logged in to your account when you are logged into Web Central.

You will use the Tk20 system for the following: 

  • Submitting your course and e-portfolio materials necessary for required course work, graduation and New York State teaching certification.
  • Reporting student teaching data. Your student teaching applications will be submitted through the online system, and you will graduate with a fully documented record of your field experience and student teaching.
  • Designing teaching portfolios from the work you have submitted through the system, as well as your student teaching evaluations, and comments from your professors and cooperating teachers. This will allow you to show evidence of your work, assessments and growth to prospective employers. Your Tk20 accounts will be valid for 10 years and will supply you with a dedicated Internet address for your portfolios.
