FSP and Kenntnisprüfung: What's the Difference, and When Is Each Required?
These two exams are constantly confused because both are part of the path to becoming a doctor in Germany (Approbation). But be careful: they are not alternatives to each other. One measures your language, the other your medical knowledge — usually two separate, sequential stages. You don't choose "this one or that one"; most candidates need both (in order).
The difference in one table
| FSP (Fachsprachprüfung) | Kenntnisprüfung (KP) | |
|---|---|---|
| What it measures | Medical language (patient/colleague/written) | Medical knowledge (clinical, pharmacology, emergencies) |
| Who runs it | Ärztekammer (Medical Chamber) | Ärztekammer / university-clinic commission |
| Format | 3 parts × 20 min (anamnesis, Arztbrief, presentation) | Oral-practical exam, ~60 min + patient examination (OSCE-like) |
| Language level | C1 professional | German assumed sufficient; the content is medicine |
| Order | Usually comes first | After the FSP, if required |
Does everyone need the Kenntnisprüfung?
No. The Kenntnisprüfung is required when your diploma's equivalence (Gleichwertigkeit) to the German degree cannot be established. There are two paths:
- Gleichwertigkeitsprüfung positive → your diploma is deemed equivalent, and you can get the Approbation (with the FSP + documents) without needing the Kenntnisprüfung.
- Deficient/not equivalent → you sit the Kenntnisprüfung to close the gap.
In practice, most physicians with a third-country (non-EU — e.g. Turkey) diploma take the Kenntnisprüfung.
What kind of exam is the Kenntnisprüfung?
The KP is an oral-practical medical knowledge exam (the equivalent of the 3rd part of the German state exam, in a single day):
- Duration: 60–90 minutes per candidate; a patient examination + written report (Anamnese, Diagnose, Behandlungsplan, Epikrise) + an oral part.
- Subjects: the emphasis is on Innere Medizin (internal medicine) + Chirurgie (surgery); plus Notfallmedizin, Pharmakologie, imaging, Strahlenschutz and the legal aspects of medicine (Recht).
- Retakes: 2 retake rights (3 attempts in total); on a retake, all subjects are tested again.
A striking figure: according to Berlin's official numbers, the first-attempt KP failure rate is ~18%, but the rate of permanent failure after exhausting all attempts is below 2%. In other words, failing on the first attempt is common, but the road almost never closes — most physicians pass in the end.
💶 Cost warning: the KP is more expensive than the FSP and varies a lot by state — e.g. Brandenburg ~799 €, Hessen ~1,350 €. Each retake is charged again; the Approbation decision fee (usually 150–700 €) is separate.
Three critical concepts
| Concept | What it means |
|---|---|
| Defizitbescheid | The official decision from the equivalence review saying "there is a substantial gap, you must take the KP." It triggers the KP requirement. |
| Berufserlaubnis | A temporary/limited (usually ≤2 years) work permit — supervised practice until the Approbation comes through. |
| Approbation | The unlimited, full, independent license to practice (the ultimate goal). |
Tip: documented clinical experience after your diploma can, in some states, offset the equivalence gap and remove the KP requirement — ask the state authority before applying (it varies).
The typical sequence
- Learn German (B2 → C1)
- Berufserlaubnis / Approbation application (to the state authority)
- FSP (language approval)
- If required, Kenntnisprüfung (knowledge approval)
- Approbation (full license to practice)
In short: the FSP asks "Can you practice medicine in German?", while the Kenntnisprüfung asks "Do you know medicine to the German standard?"
Pass the FSP first — start with rehearsal
Run an FSP simulation for your state; lock down the language side, then focus on the KP.
