The introduction of NOST led to a redesign of the curricula by dividing the educational and teaching tasks into so-called "competence modules". School performance is assessed and completed on a semester basis. In the case of a negative assessment or non-assessment, pupils can advance to the next school level and be re-tested in the relevant subject area by means of a semester examination within two semesters. While the previous system of early warning remains in place, the NOST introduces the additional institution of individual learning support for pupils by trained learning guides.
