The content and method of examinations regulated by the chamber are defined by local chambers following the national legal framework and broad guidelines of the national chamber association (Fazekas and Field, 2013). A chamber-regulated examination can receive federal recognition if it exists in a few different states (Lander), has been in place for at least five years, and attracted at least 500 candidates over a specific period of time (Hippach-Schneider et al, 2012). The federal administration approves examination rules submitted by professional organisations and provides support in organising examinations. It provides detailed guidance on how the exam should be conducted (e.g. main parts of the exam, their relative weight in the final score, types of assessment); who the examiners should be (e.g. experts coming from outside the professional association), and what level of competency the examinees should demonstrate.
