The VO-HO Netwerken (Secondary-Higher Education Networks) were set up in 2004 as part of the Deltaplan Bèta Techniek (Dutch national STEM strategy). The main goals of the networks are the professional development of secondary education teachers and principals, the continual innovation of courses and curricula and the improvement of the connection between secondary education (VO) and higher education (HO). The networks offer a wide pallet of activities for students, teachers, technical teacher assistants and heads of schools with a focus on STEM education. Currently there are are ten regional networks that consist of universities, higher education institutions, (pre-univeristy) secondary schools and business and societal institutions. The specific objectives are set by each regional network independently, in alignment with the regional context and objectives.
