Guido van Eijk has been working in secondary vocational education for 28 years and has been a team leader at Summa Elektro- & Installatietechniek since 2012, primarily in the role of practor at the Sustainability and Energy Transition Practorate for the past four years. Within this practorate, we conduct research into how the theme of sustainability can be embedded in education and aligned with current technological innovations and developments in the field of the energy transition. To this end, we participate in the Brabant public-private partnership projects ‘Daar brandt nog licht’ and ‘Brabant leert Transitiehubs Energie’. The service document ‘de Groene Draad’ has been developed in collaboration with several organizations.
