Sample-based NLSA with system-wide monitoring purposes administered regularly since the early 2000s.

NLSAs oriented at instructional improvement at the student, classroom and school level administered to different grades (ISCED 1 and 2) since the early 2010s. Schools’ and municipalities’ participation is voluntary, but has become nearly universal over the last decade.

An additional statutory assessment at the end of ISCED2 is in place since 2011. The test has no consequences for students, but participation is mandatory.
