The Vocational training includes initial training (level 1), followed by either academic studies (option 1) or master craftsman training (option 2). Both options correspond to level 2.

Initial training (level 1) follows the so-called "dual system" of vocational training, combining, during the first three years, practical training in a specialised company and theoretical education/training at the vocational training school. Trainees therefore need apprenticeship contracts with hearing aid acoustics companies for a term of three years. During these three years, apprentices will train at the National Vocational School for Hearing Aid Acousticians in Lübeck for eight terms of four weeks each.

Furthermore, at level 1, there is a four-week period of additional training at the Academy for Hearing Aid Acoustics, which is located in the same building. It complements practical in-company training; its contents and structure are closely linked to the school lessons.

Completed initial training (level 1) entitles graduates to work as hearing aid acousticians in a specialised company headed by a master craftsman or holder of a Bachelor’s degree in audiology.

Level 2 of the training course for hearing aid acousticians entitles graduates to operate a specialised hearing acoustics company and consists either of academic studies or master craftsman training.
