Why does a master’s thesis in Sweden end with another student criticising your work in public? Because the opposition seminar is a core part of the Swedish academic tradition, and it surprises many international students. Add the credit-based rules, a plagiarism-checking system that changed in 2025 and publication in an open database, and the Swedish degree project works quite differently from a UK dissertation.

This guide explains the rules for a master’s thesis in Sweden, walks through the opposition seminar, sets out what happened to Ouriginal, and closes with notes on Norway and Finland. Rules come from official university and national pages checked in November 2026; your own syllabus always takes precedence.
What is a master’s thesis in Sweden? In Sweden the master’s thesis is called a degree project (examensarbete). It is an independent, credit-rated course in the main field of study, normally worth 30 credits for a two-year Master (120 credits) and at least 15 credits for a one-year Master (60 credits). It is supervised, presented and defended at a seminar with a student opponent, and graded by an examiner who is not the supervisor.
What are the credit rules for a master’s thesis in Sweden?
Sweden has two general second-cycle degrees, and the degree project requirement is set nationally in the Higher Education Ordinance and repeated in each university’s local rules. Uppsala University summarises them as follows:
| Degree | Total credits | Main field requirement | Degree project |
|---|---|---|---|
| Master of Arts/Science (60 credits), Magisterexamen | 60 credits at second cycle (one year full-time) | At least 30 credits at second cycle | At least 15 credits |
| Master of Arts/Science (120 credits), Masterexamen | 120 credits at second cycle (two years full-time) | At least 60 credits at second cycle | At least 30 credits |
In Sweden, 60 credits equal one year of full-time study, so a 30-credit master’s thesis in Sweden represents one full semester of work, roughly 20 weeks. Uppsala also notes a planned change: from 1 January 2029, a maximum of 15 credits from first-cycle courses may be included in either degree.
Unlike the UK, Swedish rules rarely set a national word count. Length is defined by credits and by the course syllabus, so check your programme’s syllabus (kursplan) and any department template for page or word guidance.
Who supervises and who grades?
A master’s thesis in Sweden normally involves three roles:
- Supervisor (handledare): guides the work, comments on drafts and confirms readiness for the seminar.
- Examiner (examinator): a separate teacher who sets the grade. In most programmes the examiner is a different person from the supervisor.
- Opponent (opponent): another student who reviews your thesis critically at the seminar, while you in turn may oppose someone else’s thesis.
Projects carried out in companies are common in engineering and business, with an external supervisor at the company alongside the academic supervisor. The academic side still sets the grade.

How does the opposition seminar work?
The opposition seminar is the step most students find unfamiliar. Procedures vary by department, but published guidance follows a similar pattern. The Centre for Language and Literature at Lund University, for example, sets out this sequence for its MA programme in Language and Linguistics:
- Announcement. The defence is announced and the thesis is made public at least one week in advance.
- Preparation by the opponent. The opponent writes structured notes of about two pages covering the same areas as the grading criteria: research questions, relevance, theory, method, analysis, discussion, structure, use of sources, language and formal aspects.
- Opening. A chairperson, often the supervisor, introduces the respondent, the opponent and the examiner, and the respondent may announce corrections.
- Presentation. The respondent (the author) presents the thesis for 20 to 30 minutes.
- Opposition. The opponent gives an overall impression and then works through the criteria for 20 to 30 minutes, as a dialogue rather than an attack.
- Questions. The examiner asks questions (5 to 10 minutes), then the audience.
- Decision. The supervisor and examiner agree on the grade and any corrections, which should not be so extensive that they would change the grade.
The whole defence in that programme lasts no less than one hour. At KTH, departments run similar presentation and opposition seminars; students sign up to oppose another degree project, submit a written opposition report before the seminar, and some programmes also require attendance at other seminars as active listeners.
How do you prepare as a respondent and as an opponent?
As the respondent (author):
- Prepare a 20-minute presentation that covers aim, method, main results and limitations, not every detail.
- Read your own thesis again the day before and list its weaknesses. The opponent will find them, and acknowledging them calmly is a strength.
- Answer questions briefly. The Lund guidance specifically asks respondents to reply relatively shortly, without long explanations or excuses.
- Note every correction agreed at the seminar; you will need them for the final version.
As the opponent:
- Use the grading criteria as your structure, so your critique matches what the examiner assesses.
- Start with the overall contribution, then move to substantive issues such as research questions, method and argument.
- Give minor issues such as typos in writing rather than spending seminar time on them.
- Ask open questions (“How does X follow from your data?”) rather than delivering verdicts.
Opposing is usually assessed as part of your own course, so preparing it well affects your result, not only your classmate’s.
What happened to Ouriginal?
For years, Swedish universities checked student texts with Urkund, which became Ouriginal. That changed in 2025. KTH announced in May 2025 that the provider of Ouriginal would shut the system down on 31 October 2025, one year earlier than expected, after the tool had been acquired and was being phased out. Sunet, the Swedish University Computer Network, began procuring a national replacement.
Mid Sweden University explained in September 2025 that it was moving from Ouriginal (formerly Urkund) to Inspera Originality, because the supplier behind Ouriginal had been acquired and chose to discontinue the service. Linnaeus University also now uses Inspera Originality as its official system. If a guide or senior student tells you that your master’s thesis in Sweden will be checked in Ouriginal, the information is out of date: ask your department which system it now uses.
| Period | System commonly used in Sweden | What to do |
|---|---|---|
| Before 2020 | Urkund | Older guides refer to it |
| 2020 to October 2025 | Ouriginal (formerly Urkund) | Treat guidance from this period as historical |
| From autumn 2025 | Replacement systems, such as Inspera Originality at Mid Sweden University and Linnaeus University | Check your own university’s current tool and settings |
Whatever the tool, it produces a text-matching report for the examiner, who makes the judgement. Correct quoting, paraphrasing and referencing matter more than any percentage.
Where is the thesis published?
Approved degree projects in Sweden are commonly registered in DiVA, the publication database used by many Swedish universities. At KTH, an administrative decision requires all approved degree projects to be registered in DiVA; at the School of Engineering Sciences, programme administrators publish them after the supervisor or examiner sends the final version, and students submit the necessary information and consent. Because the thesis becomes public, check confidentiality agreements early if you work with a company, and plan how you will handle any later journal article based on the thesis.
How do Norway and Finland differ?
The Nordic systems share the credit logic but differ in detail.
Norway. According to Eurydice, the thesis or other independent work in regular two-year and experience-based master’s programmes must be between 30 and 60 credits, and 60-credit theses are the rule in discipline-oriented studies. In integrated five-year master’s programmes of 300 credits, the independent work is at least 20 credits.
Finland. Finnish universities require a maturity test (kypsyysnäyte) linked to the master’s thesis. Hanken School of Economics describes it as a short essay on a topic related to the thesis, showing that you know the subject area well; all students must write one.
| Feature | Sweden | Norway | Finland |
|---|---|---|---|
| Thesis credits | At least 15 (one-year) or 30 (two-year) | 30 to 60 in two-year programmes | Set by the programme |
| Public element | Opposition seminar with student opponent | Varies by institution | Varies by programme |
| Distinctive requirement | Student opposition | 60-credit theses common in discipline-oriented studies | Maturity test |
Common mistakes in a master’s thesis in Sweden
- Treating the opposition seminar as a formality and preparing only slides.
- Relying on an old guide that mentions Urkund or Ouriginal instead of checking the current system.
- Ignoring the syllabus grading criteria, which both the examiner and the opponent use.
- Signing a company confidentiality agreement without checking how it fits DiVA publication.
- Leaving opposition preparation to the last day, although it may be assessed.

Frequently asked questions
How long is a master’s thesis in Sweden?
Length is set by credits rather than a national word count: at least 15 credits for a one-year Master and at least 30 credits for a two-year Master. Departments often give page guidance in the syllabus or template, so check yours.
Is the opposition seminar graded?
The seminar is part of the examination of your thesis, and acting as an opponent is often an assessed part of the course. The examiner decides the grade after the seminar, sometimes requiring minor corrections.
Do Swedish universities still use Ouriginal?
No. The service was discontinued in autumn 2025. Universities such as Mid Sweden University and Linnaeus University moved to Inspera Originality, and Sunet procured a replacement for the national service. Ask your department which tool applies.
Can I write my master’s thesis in Sweden with a company?
Yes. Company-based degree projects are common, especially in engineering and business. You will have an academic supervisor and examiner, and you should agree confidentiality and publication terms before starting.
Is a master’s thesis in Sweden published online?
Many are registered in DiVA after approval; KTH, for example, requires all approved degree projects to be registered there. Some content can be restricted if a confidentiality agreement applies.
