A longitudinal study of doctoral candidates and doctorate holders

Nacaps is a long-term study of doctoral candidates and doctorate holders and includes regular surveys on career paths of highly qualified academics in Germany – for the use of researchers and academic policy makers.

The study is a joint project of the German Centre for Higher Education Research and Science Studies (DZHW) and more than 50 doctoral degree-granting universities across Germany. The project is funded by the Federal Ministry of Education and Research (BMBF). For the first time, doctoral candidates were surveyed for this study in February 2019. The second round of the survey has closed in April 2021. The first cohort of participants of the panel study was invited to participate in the follow-up survey in June 2021. 

Follow-up survey 2022

Did you participate in the 2019 or 2021 NACAPS survey of doctoral researchers and doctoral graduates in Germany?

If so, we would like to invite you to participate in the follow-up survey! You will soon receive an invitation email from the DZHW.

Even if you feel that you did not follow the usual path to or during your doctoral studies, if you have already completed your doctorate or are no longer pursuing it, your participation is very important. Only with a wide range of respondents can we gain a full picture of doctoral conditions in Germany in general, and at Goethe University Frankfurt in particular. Join in to make the “Frankfurt” voices (be) heard!

You can find the results of the survey at www.nacaps-datenportal.de. Further key evaluations on topics such as funding, employment or the health of doctoral researchers as well as the press response to the study will be published at www.nacaps.de.

The study results will be

  • made available to NACAPS’ partner institutions for monitoring, controlling and quality management via our data portal
  • prepared for the expert public and decision makers in higher education and science policy in the form of reports, as a basis for evidence-based monitoring of young researchers
  • made available to the scientific community for research purposes via the DZHW Research Data Centre (FDZ) in the form of anonymised data sets (scientific use files).

Your participation will influence future decisions which are relevant for early career researchers.

How do you participate?

You will receive a personal invitation via email including a link that grants you access to the online survey.

The third round of the survey starts in spring 2022.

You receive a personal invitation to each round of the survey, if your contact data is valid and recorded by one of the following procedures:

  • Acceptance as a PhD candidate at one of Goethe University's faculty
  • Registration as doctoral student
  • Participation in the GRADE program
  • Member of a structured PhD Program at Goethe University

The contact information are pooled to get a list of all PhD candidates at Goethe University. If you request a personal invitation with an access link, your data will be added to this list. This contact information is used only for survey invitation and will be deleted afterwards.

The procedure has been reviewed and verified by Goethe University's data security representative.

What happens to your data?

If you give your consent, Nacaps will save your personal contact data so they can contact you for follow-up surveys. This information will be saved separately from your survey answers in a protected area of DZHW’s in-house server. The information given in the survey is pseudonymised before being processed (i.e. cleared of names or addresses).

Sensitive information and all open statements are specially protected to ensure that they cannot be traced back to individual participants.

Study Design

Since 2019, new doctoral candidates (from 2021 also doctoral holders) are included in the panel at regular intervals. Their consent provided, existing participants will be invited to the survey repeatedly.

If you agree to resubmit the follow-up questionnaire when registering for the first time, your contact details will be stored in compliance with the privacy policy. After two years, you will be invited again as a doctoral candidate or as a postdoc for a follow-up questionnaire.

The survey is carried out in cooperation with over 50 higher education institutions, including Goethe University. Doctoral candidates and doctorate holders throughout the country are surveyed at regular intervals on the study conditions for their doctorates, career aims and professional development, as well as on their general life situation. Consequently, the panel history will give an overview of career paths and the biographical development of doctoral candidates beyond the immediate phase of the dissertation. Detailed information on the study design can be found on the Nacaps website.

Survey Findings

The results of the first survey in 2019 have been evaluated and are available via the NACAPS data portal. The data portal provides an overview of the conditions for doctoral research and the situation of doctoral candidates on the basis of 32 indicators and is regularly supplemented with current data. The data basis is formed by the responses of more than 20,000 doctoral candidates at 53 German universities eligible to award doctorates who participated in the first doctoral candidates survey of the panel study in spring 2019.

The aggregated and evaluated datasets were also made available to the participating universities anonymously in a data portal and as a microdata set. They provide most useful insights into the careers and living conditions of doctoral candidates and doctorate holders in Germany. As a result, they can effectively increase the quality of their qualification programs and higher education offers. Relying on the new and comprehensive data on doctoral study conditions and doctorate success, GRADE, too, aims at supporting doctoral candidates and postdocs even more specifically on their individual pathway during and after their doctorate.

The first results of the second survey in 2021 are expected to be available from the beginning of 2022.
