+## About the dataset
+
+The dataset comes from student teachers, who collect case studies from their supervising teachers at their teaching practicum. These data are collected through standardized forms that the student teachers complete with their accompanying teachers. The collection of the dataset runs between 2023-2026. All students involved in the collection are informed of the use of the data and have given written consent. Additional case studies will be collected on an ongoing basis, through registered users of the Edustories.cz platform that choose to publish their anonymous case studies. All data is subject to multiple stages of anonymisation, so they do not contain any real names of schools, school staff or students.
