Assessment sample

The series of longitudinal datacollection started in 2003 on three nationally representative samples, in grade 1, 5 and 9. In the first four years of the program (2003-2007) nearly 12.000 students were involved. The first phase of the research program was completed in 2007, since the oldest cohort, sample 1, left public education (completing grade 12). Sample 2 left primary school (completing grade 8) – their tracking and further involvement in the assessments is one of the objectives of the program. Sample 3 left primary school in 2010 and completed their maturation exam in 2014. This is the first sample where we collected data throughout their public education. Sample IV. left primary school in 2014. New samples were launched in 2011 and 2015 (sample V. and VI.).
