A recent study places Fresenius among the top 500 companies in terms of career training programs in Germany. Criteria used for judgement were the quality of supervision, in-house training, company engagement, success rate and innovative teaching methods. The companies were rated by the business magazine Capital and the internet portal, ausbildung.de. Fresenius received a best possible five-star rating for its on-the-job training and dual-studies, a combination of theory and on-the-job training, programs. The company trains more than 4,000 apprentices and dual-studies interns.
