The main goal of 'CILSNL Citizenship Education 2010-2011' is to provide more information on the extra-curricular activities offered at Dutch secondary schools participating in the 'Children of Immigrants Longitudinal Survey in Four European Countries' (CILS4EU; Kalter et al., 2013) and the 'Children of Immigrants Longitudinal Survey in the Netherlands' (CILSNL; Jaspers & Van Tubergen 2014; 2015). The survey consists of closed and open questions on school activities offered relating to the topics ‘war and freedom’ and ‘citizenship and democracy’ offered in the school year 2010-2011. A schoolid is provided to match the school-level data (N = 59) with the student-level data of CILS4EU/CILSNL.
