Since the 1976 academic year, restorers have, in a four-year technical school study course, been trained in the following specialties: prehistoric cultural assets and those stemming from early history, musical instruments, archaeological excavations, books and papers, metal, wood, textiles as well as ceramics and glass. The course is conducted by the department of training and further training at the Museum fuer Deutsche Geschichte. Basic training is provided centrally while matters specific to the various subjects are handled at different consultation centers generally situated in restoration workshops in possession of the necessary facilities. The experiences gathered in running this course are being used continuously to improve the entire training process. An extension of the course through the introduction of two further specialties -- leather and stones -- is being considered.
