SIGMA is an initiative of the SURF foundation (http://www.surf.nl), and aims at facilitating continuous learning paths in education in mathematics between secondary education and higher education. In this way SIGMA intends to attack the problems regarding the transition 'from pupil to student' for mathematics. SIGMA is the platform for the exchange of knowledge, experiences and helps in addressing the problems of prerequisite mathematics. SIGMA concentrates on four main topics:
content and education, assessment and testing, exchange and standardization, and the SIGMA award for best teacher and practice in education. SIGMA is a community rather than a single project. The community accommodates many projects, programs and working groups.

Current projects are MathMatch, NKBW and Webspijkeren. Current workgroups are engaged in synchronization of assessments, standardization of tests, the initiation of new NAP projects, and the granting of the SIGMA award.
