MARKO (Mathematik- und Rechenkonzepte im Vorschulalter)

MARKO is an individual, child-friendly individual test that helps analyze a child’s prerequisite’s for his/her future development with regard to mathematical competencies. Delays as well as progress in a child’s development can be described quantitatively and qualitatively. The latter is based on theory-based grouping of items. Repeated testing has the advantage of being able to retrace the effects of individual support and of changes of a child’s knowledge. MARKO has been applied in multiple countries and validated in a number of additional countries (see world map).
