In the 2001/2002 school year, Baden-Württemberg was the first German state to take account of the growing importance of biotechnology at grammar schools, which led to the establishment of "biotechnological grammar schools." The new course, as offered by the Käthe Kollwitz School in Esslingen, is designed to strengthen the profile of the natural sciences and to boost young people’s interest in biotechnology, a sector which looks to have a promising future. Biotechnology grammar schools offer a six-hour biotechnology profile course, which is complemented by bioinformatics, chemistry and special biosciences areas and practical courses.
