Assessment Software

The College of Education and Social Work (CESW) uses Tk20 by Watermark as a comprehensive online data management system for assessments of student learning outcomes and field placements. Tk20 by Watermark establishes electronic documentation for continuous improvement of our programs and accreditation. Students will use this system to complete key unit and program course assignments, field applications, field experience binders, surveys, and portfolios.

All students who will be student teaching during the 2022-2023 academic year are required to have a Tk20 by Watermark account.  New students and students who have not previously purchased a Tk20 account should NOT purchase one. If you have any questions, please contact
