2025 - 2026
Admission requirements for students who will start in September 2025 and in February 2026.
Please note: only the specialisation Governance of Violence is open for registration in February 2026.
Holders of one of the following degrees may be admitted to the programme:
- Direct admission: When you have a bachelor’s degree in Security Studies, Public Administration, Political Science, European Studies or International Relations from any Dutch recognised research University, you can be directly admitted. You can register through Studielink without needing to complete an application in Leiden University’s application system (Usis).
- When you have a bachelor’s degree from an accredited research university provided the student meets the requirements across two pillars. First, at least 30 ECTS obtained from courses in the fields of governance, crisis or security related knowledge. Second, at least 20 ECTS related to empirical research skills in social sciences or similar empirical research skills. Register through Studielink and complete your application in Leiden University’s application system (uSis).
- When you have a bachelor’s degree in Safety and Security Management Studies (SSMS) at The Hague University of Applied Sciences and have fulfilled the following academic criteria.
Please note: you will have to apply through Studielink and the subsequent uSis application portal.
If you meet the conditions under 1, you only need to apply through Studielink. If you do not meet the conditions under 1, you will need to apply through Studielink and through the online application system (uSis). You will be assessed on an individual base on proficiency in the English language and the requirements mentioned in 'Elaboration'.
As this study programme is taught in English and all study activities must be undertaken in English, it is essential that you have a good level of proficiency in written and spoken English.
The following requirements apply*:
- IELTS Academic modules only, on paper or on computer: 6.5 overall, with at least 6.0 for each separate component score.
- We do not accept IELTS Academic online.
- We do not accept IELTS General Training, IELTS Indicator, or IELTS One Skill Retake
- TOEFL internet based: 90 overall, with at least 20 for each separate component.
- We are not able to accept The TOEFL IBT Home Edition™, except in the following situation only:
You are unable to take an in-person test on location because test centres are inaccessible or closed due to unsafe conditions in a country. - We do not accept the following types of test: TOEFL My Best™ scores (multiple test scores combined), TOEFL Essentials™ or institutional tests such as ITP.
- We are not able to accept The TOEFL IBT Home Edition™, except in the following situation only:
- Cambridge English Exam C2 Proficiency, or C1 Advanced (180), with a minimum score of 169 for each separate component.
Note that English test results may not be more than two years old and must be obtained in one single test.
*You do not have to submit an English proficiency test if you have completed your education in the USA, UK, Ireland, New Zealand, Australia, Canada (except French-taught programmes in Canada) Singapore, South-Africa or Malta; or if you have obtained an English-taught International Baccalaureate™; or if you have completed a Dutch VWO diploma or an English-taught bachelor at a Dutch research university or (for September intake) a diploma of an English-taught higher professional education (hbo) programme completed at a Dutch university of applied sciences.
For detailed information, including exemption criteria and methods of submission, refer to English language proficiency.
Holders of a bachelor's degree from a research university with a maximum of 5 ECTS of deficiencies, can eliminate their deficiencies in the curriculum by showing relevant knowledge with their extracurricular courses as shown on the below table:
Pillar 1: Governance, crisis and security related knowledge | At least 30 ECTS obtained at a recognized research university in courses in the field of governance, crisis or security knowledge. | If you do not meet the requirements specified in the cell to the left, and your deficiency is a maximum of 5 ECTS, this can be bridged by doing 3 MOOCS on governance, crisis and/or security by a recognized research university. Official certificates must be obtained for these courses. Examples are: MOOCS related terrorism studies, crisis governance, cybersecurity governance, and risk in a modern society, etc |
Pillar 2: Empirical research skills in social sciences |
At least 20 ECTS of the course curriculum at a recognized research university is related to empirical research skills in social sciences. Please note that ECTS obtained for a thesis are only considered when it concerns an empirical research project in the social sciences. |
If you do not meet the requirements specified in the cell to the left, and your deficiency is a maximum of 5 ECTS, this can be bridged by doing 3 MOOCS on empirical research skills in social science by a recognised research university. Official certificates must be obtained for these courses. Examples are: MOOCS related to quantitative research methods, qualitative research methods, research design, social science methods, etc. |
The above elaboration on the requirements give an indication whether you will be admitted or not. At the same time, there are no assurances given. The first step by the Board of Admission is to examine the degree obtained. If this degree significantly differs in content from the master programme (e.g.: a degree in biology, physics, mathematics, industrial engineering, language studies), it will not be possible to bridge these deficiencies by online courses.
- Bachelor degree in international studies:
watch out for deficiencies in research skills. Make sure to submit writing samples, follow electives that are methodological in nature, and complete the online courses if there is still a maximum 5ECTS deficiency. - Bachelor degree in criminology:
students generally meet entry criteria across the two main pillars, except when the degree is closely aligned with a law degree, in which case they should watch out for deficiencies in the empirical research skills in social sciences pillar. - Bachelor degree in history:
watch out for deficiencies in the governance aspect, and brush up on research skills. Make sure to submit writing samples, follow relevant electives, and complete the online courses if there is still a maximum 5ECTS deficiency. - Bachelor degree in law:
watch out for deficiencies in crisis and security related topics (a course on criminal law is as such not sufficient), and especially research skills. Make sure to submit writing samples, follow relevant electives, and complete the online courses if there is still a maximum 5ECTS deficiency. - Bachelor degree in psychology:
watch out for deficiencies in the governance aspect. Follow relevant electives, and complete the online courses if there is still a maximum 5ECTS deficiency. - Master degrees in the above fields:
a Master degree should strengthen your knowledge on at least empirical research. Make sure to submit writing samples. - Bachelor or Master degree from a University of Applied Sciences (HBO):
though these programmes might touch upon one or even both pillars in the curriculum, they do so from a perspective of applied sciences. Hence applicants lack theoretical background needed to start the Master’s programme. It will almost be impossible to adhere to the requirements.
Minor
Finally, a minor programme can be a great way to increase knowledge on the two pillars. Currently, the Institute of Security and Global Affairs offers five minor programmes, but other minor programmes may also prove valuable:
- Security, Safety and Justice: the different courses touch upon each of the two pillars.
- Intelligence Studies: the different courses touch upon each of the two pillars.
- Global Affairs: the different courses concentrate on crisis, security and governance topics.
- Violence Studies: the different courses concentrate on crisis, security and governance topics.
- Cybersecurity and Cybercrime: the different courses concentrate on crisis, security and governance topics.
It is not mandatory, but to aid in your assessment, we highly recommend to include a placement letter in English, in which you explain how you meet the admission requirements. This serves to help the Board of Admissions gain further insight in your experiences (work and/or education) that might contribute to establish admissibility to the programme. Make sure to use this template.
You can download the template, fill it in, and add it to your application. List relevant academic courses or other relevant academic experiences (such as internships, summer courses, thesis or extra-curricular research), including if applicable the amount of ECTS or credits assigned to them.
For everything you list, it is recommended you hand in supporting documents, such as course descriptions, syllabi or writing samples. You can upload supporting documents via the application portal in uSis (ideally, integrate the supporting documents into one pdf).
