• Pure observership (Hospitation-like): you only observe, no independent clinical work, usually unpaid.
• Paid clinical role: if you hold a Berufserlaubnis and actually treat patients under supervision, it can be a paid position close to an Assistenzarzt role.
What decides it is your legal status (do you have a BE?) and what the contract says you may do. Before accepting, ask the clinic in writing: Is this paid? Will I work clinically or only observe? Do I need a Berufserlaubnis? Who supervises me, and am I insured? Never start a “Gastarzt” arrangement without those answers on paper.
