Abstract: | This article concerns psychometric aspects of the Finnish Early Numeracy Test, which has been translated from the original Dutch Early Numeracy Test. The advantage of the test is that young children's numerical skills can be assessed systematically, which was not possible previously in Finland. A norm study was conducted in which the test was administered to a representative sample of 1,029 Finnish children. The reliability and validity results justify the use of the test as an early-childhood screening test and in research on number sense. The indicative effects of gender, parental professional education, domicile and number of siblings are discussed. |
