The students' email addresses are provided for the Enrolment and Examination Office to send invitations.

The basis for this is § 5, para. 1 NHG (Evaluation of Research and Teaching) in conjunction with § 17, para. 1-4 NHG (Processing of Personal Data) as well as an application for the disclosure of personal data approved, among others, by the Data Protection Officer and the Vice President for Studies and Teaching.

In accordance with Art. 5, para. 1 c EU-GDPR (Principles for the processing of personal data), attention has been paid to data minimisation in the course of the application.

The students' contact details are always saved and stored separately from the survey data on an external storage medium. Contact details are never linked to survey results, nor can they be.

The addresses will be used solely for the purposes of conducting the survey and will be deleted once the survey is completed.

Before the mass emails are sent, the email addresses are assigned a link with an individual access code that students use to log into the online survey.

With the help of this code, respondents can take part in the online survey (sufficient protection against so-called ‘third-party completion’ is thus ensured).

It is not possible to match the access code to the answers in the questionnaire because the access codes are not included in the survey data.

The central student and alumni surveys are evaluated by the University Planning and Quality Assurance staff unit.

The administrative department provides the departments and institutions with the results of the individual surveys at various levels via a central, restricted-access storage location, insofar as the response rates allow. As a rule, the minimum number of responses for a report is n = 5. The survey results are only published in aggregated and anonymised form, so that no conclusions can be drawn about individuals.
