The agenda uses a similar mechanism to the course topic lists
The Information system Studies Topic Lists
for the selection of thesis topics, applications for various events, schedules for training courses, etc. These topic lists usually concern a large group of students, typically whole courses.
Topic schedules are created by authorized persons from the faculty (access right s_rozpisy or s_studium). They also set the timetable of work with the topic list displayed for the selected topic list or in the topic creation application.
The topic supervisors themselves will define and publish/offer the thesis topics to the students and gradually specify the assignment or title. Before the thesis defense, the study department will use the information obtained to transfer the thesis to the thesis archive and to print final certificates, etc.
A detailed description of the options is given in the question Outlines for Student Rosters → Final Thesis Evidence.
