There has been a close collaboration since June 2009 with the Reformed Primary Education within the scope of Greijdanus, namely Accretio and Scholengroep Hannah. The organisations work together or coordinate their policies with each other in the areas of identity, care, continuous learning and organisational support. This resulted in a collaboration under the name ‘GO|ON’ (Gereformeerd Onderwijs Oost Nederland) – Reformed Education East Netherlands.

Together, the following ambition was formulated regarding Primary Education, which therefore also applies to Greijdanus:
Together with the Reformed primary education in the region, we offer education and related services to all children from 0-18 years old and their parents. Support and care are areas of service.

Our target group is located in the East of the Netherlands and is detailed in our Identity Document.

We strive for direct steering of education and education-related processes.We support this with efficient business operations. Our focus is in on the child and the group, for which we deploy passionate and professional staff.
