If you study a STEM subject (MINT-Fach), you choose a field with very different career profiles. Computer science, engineering and chemistry differ clearly in work location, physical strain and responsibility. For an occupational disability insurance (Berufsunfähigkeitsversicherung, BU), the decisive factor is therefore less the subject you study than the activity you actually carry out afterwards.
In short: A BU for STEM students depends mainly on the later activity profile. Computer science is often office-based, engineering can involve construction sites, workshops or design work, and chemistry often means laboratory work with hazardous substances. Each tariff sets its own classification. Last updated: October 2026.
The Key Points at a Glance
- The subject alone does not decide the classification. What counts is the work you do in your daily professional life.
- Computer science, engineering and chemistry involve different physical and health-related strains.
- Insurers assign professions to their own occupational groups. The assignment differs from provider to provider.
- Descriptions of your activities in the application should be specific, so that there is no later dispute about your profession.
- A future insurability guarantee (Nachversicherungsgarantie) can make later adjustments easier. Whether and under which conditions this applies is set out in the tariff.
How Does a BU Classify STEM Careers?
The statutory definition of occupational disability is based on the profession you last practiced, in the form it had without the health impairment. Under § 172 of the Insurance Contract Act (Versicherungsvertragsgesetz, VVG), what matters is whether, due to illness, bodily injury or an age-atypical decline in strength, you are wholly or partly and permanently unable to carry out this profession. During your studies, there is no profession practiced yet, so in most cases the profession you are aiming for is used.
Assigning a profession to an occupational group is the task of the insurer. It describes which parts of the activity count and how strongly this affects the premium. If you mainly work at a desk in practice, you are usually classified differently from someone who spends most of their time on site. Whether a mixed profile is rated more favorably or less favorably in a tariff depends on the specific condition. The job title alone is not enough for this. An insurer can also consider whether management tasks or project responsibility predominate.
What Are the Differences Between the Subjects?
The overview below shows typical fields of activity and strains. It is not a classification but a guide that helps you prepare your answers in the application.
| Subject | Typical fields of activity | Common strains | What to note in the application |
|---|---|---|---|
| Computer science | Software development, system administration, consulting | Long hours at the screen, tension, project pressure | Whether home office, project work or on-site work predominates |
| Engineering | Design, production, site management | Construction sites, workshops, business travel, noise | Share of on-site work and office work |
| Chemistry | Research, quality control, production | Laboratory work with chemicals, shift work | Describe the handling of hazardous substances and shift work precisely |
These differences matter because insurers often assess activities with a higher physical risk differently from pure office work. At the same time, the health assessment is decided not by the subject but by your state of health. Both together determine the contract. The duration of individual activities, for example when handling hazardous substances or working on a building site, also belongs in the description. An application that records these details only roughly may lead to follow-up questions when a claim is assessed.
Many STEM students gain early practical experience through internships or working student jobs. These activities show how the profession may look later and help with the classification. It is important to describe them precisely, because an internship in a laboratory says little about a later design position. The application asks about the activity itself, not the title of the position.
Which Health Questions Matter for STEM Subjects?
The insurer asks about illnesses, treatments and findings from recent years. This is governed by § 19 VVG on the duty to disclose (Anzeigepflicht). For STEM subjects, depending on the activity, questions about visual problems from screen work, allergies in the laboratory, back complaints on construction sites or hearing problems in noisy workshops can become important.
If you do not answer questions completely, you risk your contract when a claim is made. This applies regardless of the subject. Information about earlier findings is particularly important. These may seem unimportant during your studies, but the application asks about them explicitly. The guide on BU health questions during your studies gives an overview of typical questions, and the guide on BU with a pre-existing condition explains the topic of earlier illnesses.
How Do You Check the Classification in the Tariff?
A note in advance: comparing occupational groups by subject is only a first step. What matters is which activity is actually described in the contract. An engineer whose work consists mainly of planning at a desk has a different risk profile from someone who is on a construction site every day, even if both completed the same degree.
The classification is not found in the advertising but in the tariff terms. Pay attention to the definition of occupational disability, to any referral clause (Verweisungsklausel) and to the rules for professions during training or studies. Also check whether the insurer treats home office, project work or field work equally. Such details decide the claim in an emergency.
Frequently Asked Questions
Is a BU for computer science cheaper than one for engineering?
There is no general answer. The premium depends on the tariff, your age at entry, your health information and the occupational group. The subject is only one of several factors, so offers should always be compared for your specific profile.
What happens if I change my activity during my studies?
A change, for example from office work to a construction site, changes your activity profile. The insurance cover refers to the profession you last practiced or the one you are aiming for. Whether a notification is required is clarified by the insurer on a case-by-case basis. The guide on changing your course and BU describes the typical questions.
Can I still adjust my BU after my master’s degree?
Some tariffs include a future insurability guarantee, which allows you to increase your cover after you start work, without the full health check applying again. Whether and under which conditions this is possible is set out in the tariff. An overview is provided in the guide on the future insurability guarantee.
Do shift work and working hours play a role?
Yes, because shift or weekend work changes the strain and therefore the health information required in the application. Shift work can occur in chemistry, and in engineering, assembly and on-call duties are possible. Describe working hours in the application as they actually occur in everyday professional life, not only as an ideal.
Is chemistry a special case for a BU?
Laboratory work brings different strains than office work, for example from hazardous substances or shift work. Whether such activities are rated differently in the tariff can only be clarified with the specific contract. Ask the insurer specifically how laboratory professions are classified before you sign.
Your Next Steps
- Describe your intended activity in concrete terms, with shares of office, laboratory, workshop and on-site work.
- Ask the insurer to confirm the classification of your intended profession in text form.
- Answer the health questions completely and have findings ready if they are requested.
- Compare the tariffs by conditions and classification, not only by premium. A personal assessment is available through Academycon’s advisory service (in German).
