Tk20 by Watermark is an online assessment management system required to upload and store student and program data for state and national accreditation purposes. COEHS students will upload certain tasks in Tk20 so their development can be assessed according to standards associated with their program. Tasks could include applications, course assignments, field experience evaluations, and content portfolios.
Students and assessors will be notified by department staff, course instructors, or the Assessment Office when a task is due in Tk20.
Compatibility when using Tk20

* Tk20 recommends using Mozilla Firefox if you work on a Linux® platform.
COEHS students will be notified to purchase Tk20 at different times in their student career based on their program specifications.
Accounts remain active for seven years, giving the student access to any work and evaluations completed in their Tk20 account.
(Faculty, supervisors, and site staff are not required to purchase their Tk20 account.)
After purchase, it can take up to 10 business days for your account to be activated. The Assessment Office will email you your login information and additional instructions once your account is active.
You can access your account at uwosh.tk20.com.
Avoid Losing Work
- Tk20 should only be opened in one window. If you open Tk20 in multiple windows, you will lose work.
- Don’t use your web browser buttons to navigate in Tk20 (back button, etc.) You could also lose work and be signed out.
- Use the navigation buttons built within Tk20 only.
