FSP and Kenntnisprüfung: What's the Difference, and When Is Each Required?

✍️ Dr. Mehmet Ünsal📅 June 2, 2026⏱️ ~6 min

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

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

ConceptWhat it means
DefizitbescheidThe official decision from the equivalence review saying "there is a substantial gap, you must take the KP." It triggers the KP requirement.
BerufserlaubnisA temporary/limited (usually ≤2 years) work permit — supervised practice until the Approbation comes through.
ApprobationThe 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

  1. Learn German (B2 → C1)
  2. Berufserlaubnis / Approbation application (to the state authority)
  3. FSP (language approval)
  4. If required, Kenntnisprüfung (knowledge approval)
  5. 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.
