In 2004, Germany dropped the requirement of a master’s certificate for more than 50 crafts. On 14 February 2020, it brought the requirement back for twelve of them. The twelve include tilers, screed layers, parquet layers, interior decorators, turners and wooden toy makers, coopers, glass finishers, and organ and harmonium builders. Anyone who wants to open a business in these trades again needs the Meisterbrief. Existing businesses were protected. When the Bundestag voted in December 2019, the stated aim was to improve quality and make training attractive again.
