Tk20 by Watermark™
Texas Woman’s University formerly used Tk20 by Watermark™, a comprehensive data management system that provided tools to ensure continuous quality of our educator preparation programs (EPPs) while maintaining state and national accreditation.
IMPORTANT: Tk20 has been replaced with Student Learning & Licensure (SL&L) and is no longer in use. Please visit the TWU EPP SL&L page for information regarding TWU's current EPP admission application for Initial Teacher Certification or Professional Certification, Clinical Teaching application, and course activities pertaining to certification completed through the platform.
Previous observation and field-based experience hours that were logged into Tk20 in undergraduate and graduate courses are still accessible on the platform to view. Click on the Log in to Tk20 Paid Student Accounts button below to find previous time logs used. Starting Fall 2025, time logs are now submitted through SL&L.
