The Netherlands Research School for Information and Knowledge Systems (SIKS) is a Dutch Research School established in 1996 and successively accredited by the Royal Netherlands Academy of Arts and Sciences (KNAW) in 1998, 2003 and 2009. SIKS recceived its most recent international recognition in February 2016, after a positive quality assessment by an intenational review committee, that was established under auspices of VSNU, NWO and KNAW. The committee was asked to perform an external review of the research in Computer Science in the Netherlands of nine universities and three research schools. The quality assesment was conducted in accordance with the Standard Evaluation Protocol for Public Research Organisations (SEP) of 2015 specified bu VSNU, NWO and KNAW.

SIKS is a self-organized and self-financed network organization in which currently over 500 IKS-researchers,including nearly 250 PhD-students cooperate. Representing the vast majority of IKS researchers in the Netherlands, it provides these researchers with a platform for cooperation, information exchange and dissemination of knowledge. In SIKS these researchers shape a nationwide educational program in a way that cannot easily be achieved by local faculties or graduate schools. At present, SIKS brings together nearly 50 research groups from 11 universities in the Netherlands and from CWI (Centre for Mathematics and Computer Science), headed by over 50 full professors. In the period 2009-2015 over 300 SIKS PhD-students have successfully defended their theses and published their work in the SIKS dissertation Series.
