An occupational disability insurance (Berufsunfähigkeitsversicherung, BU) during your biology studies protects your income if you can no longer practise your profession because of illness or an accident. Biologists work in laboratories, in the field, in public authorities, in research and in science communication. Fieldwork in particular makes cover in this subject special.
Short answer: Under the joint structural guidelines of the Standing Conference of the Ministers of Education and Cultural Affairs (Kultusministerkonferenz, KMK), a bachelor’s degree takes six to eight semesters and a master’s degree two to four semesters (Last updated: October 2026). For occupational disability insurance, what counts is whether your work takes place mainly in the field, in the lab or at a desk. The target job should be described in the contract accordingly.
The key points at a glance
- Fieldwork: Terrain, weather and contact with ticks are part of many activities.
- Career fields: Research, environmental authorities, nature conservation, environmental laboratories, science communication and teaching.
- Fixed-term posts: Research positions are often fixed-term and frequently change between projects.
- Health questions: Infections, vaccinations and treatments must be disclosed completely where you are asked about them.
- Referral: A move from the field into administration may count as reasonable under the contract.
Field, lab or desk: where will you work later?
Biology is a subject with very different working environments. Many graduates combine several of them, for example sampling in the field and analysis in the lab. The overview shows where the strain lies and what to consider for your cover.
| Work environment | Typical activities | Note for BU |
|---|---|---|
| Field | mapping, sampling, monitoring in all weather | Physical strain and accident risk; tick bites are possible, so state vaccinations carefully |
| Laboratory | microscopy, cultures, sequencing, analysis | Chemicals and biological agents; watch for skin contact and airway complaints |
| Environmental or nature conservation authority | expert reports, permits, coordination with stakeholders | Mostly at a desk; a referral under the contract may apply |
| University and research | research, teaching, third-party funded projects | Fixed-term contracts and changing tasks |
Fieldwork and infection risks in the application
Ticks can transmit Lyme disease and, in some regions, tick-borne encephalitis (TBE), against which a vaccination exists. Anyone working in the field comes into contact with these more often than others. For the application this means: if the insurer asks about infections, vaccinations or treatments, you must disclose them completely, even if they seem harmless to you.
Health questions cover what the insurer asks in text form. Under § 19(1) VVG, you must disclose the circumstances about which it has asked. If you are unsure whether an illness is relevant, discuss the question with your treating doctor and note the answer. The key points on health checks from medical studies also apply here, because the logic of the disclosures is identical: Medical student disability insurance: timing and rules.
Referral: from the field to the authority
Many biologists move from the field into administration or teaching over the course of their careers. Under § 172(3) VVG, the insurer may require under the contract that you do not take up any other activity that corresponds to your training, abilities and previous social standing. Whether this applies in your case is set out in the terms, not in the law itself.
For field-based occupations it is therefore important that the contract explicitly reflects the physically demanding activity. Imagine you can no longer work in the field, but can still work in an environmental authority. Then the referral rule determines whether the BU pension is reduced or excluded. A look at the terms clarifies this question before it becomes urgent.
Step by step: check your cover
As an example, the division of work can be expressed in percentages. Suppose you work 60 percent in the field and 40 percent at a desk. This split is an assumption, which you should adapt to your own case.
- Describe your day-to-day work during your studies and later in percentages, separated into field, lab and desk.
- Transfer this split into the job description in the application.
- Ask how the insurer classifies this split and which activities it treats as equivalent.
- Check the referral clause before you sign.
Frequently asked questions
Should I take out BU early as a biology student?
Taking out cover early usually brings a lower premium, because age and health are still favourable. At the same time, during your studies you often do not yet know where you are heading. A tariff with a clear description of the target job can cover both, and you should ask whether it also covers moves between fieldwork and the lab.
Does a student assistant job at the university count as an occupation?
What counts is the activity you last practised (§ 172(2) VVG). During your studies this is often the student assistant job or your status as a student. After graduation this can change, so a later adjustment of the contract is something to keep in mind.
How should I handle tick bites in my medical history?
Whether a single bite must be disclosed depends on the specific question in the application. If the insurer asks about infections or treatments, you disclose the treatment. When in doubt, your doctor remains the right contact before you leave anything out.
Are there biology jobs that are harder to insure?
The classification is the insurer’s decision. Activities involving hazardous substances, heights or difficult terrain are often examined more closely than purely office work. Check the information in the application especially carefully and ask if anything is unclear.
What to do now
- Write down your target job and the shares of fieldwork, lab and office.
- Have each provider confirm in writing how your target job is classified.
- Read the referral clause and check which activities the insurer may treat as reasonable.
- Gather records of treatments, vaccinations and infections before you complete the application.
