Southern’s On-line Assessment System

Tk20 is an online assessment system that allows you to organize and upload relevant professional documents. Faculty members will be able to score your assignments, evaluate your progress in accordance with state regulations, and document your readiness for certification. It helps us ensure that you receive the necessary training to become certified in your field, as an excellent, well qualified professional.

In Tk20 you will upload representative assignments, professional documents, and other materials related to key program assessments including field experiences, student teaching, and clinical placements. Please note that all College of Education and certification students must purchase Tk20.

In addition, as long as your Tk20 account is active (7 years from purchase date), you have the option of creating an electronic presentation portfolio that may include documents, sample student projects, pictures, videos, etc. This portfolio is completely customizable and can be personalized to your needs. Tk20 organizes this customized information into one convenient link that you can send to various potential employers, supervisors, or whomever.
