Additional Qualification Zoo Specialist Knowledge (IHK)

By taking the examination for the additional qualification “Zoofachspezifisches Wissen” [Specific knowledge for the pet trade] in front of the Chamber of Industry and Trade (IHK), apprentices and employees in the specialist pet trade demonstrate their expertise on mammals, ornamental birds, freshwater and salt water aquarium fish, and reptiles.
It adds specific knowledge to a retail apprenticeship, while providing qualified staff and future leaders for specialist shops. The examination is open to anyone who has completed a commercial apprenticeship.
Official vets can recognise the additional qualification as a substitute for the expert interview under § 11 German Animal Protection Act (Tierschutzgesetz).
