Before the students hand in their master’s theses for evaluation, it should go through the language response process.See the Language Center for more information on language response.
The Accessiblity directive ( (306/2019) states that master's theses should be accessible for people with disabilities, as they are available on the web. See instructions for making your Word and PDF documents accessible to people with disabilities
Check with your students that they have gone through language response and checked that their thesis document is accessible.
