The present study aims at exploring if a sample of Swedish grade 3 pupils reported any test anxiety and whether there were any relations to performance in different mathematical areas. Overall, test anxiety explained 20% of the variance for the total mathematical score, with the subscale “thoughts” as the significant predictor. The model of test anxiety also explained Number understanding, Mass and Time, Patterns, and Mathematical problems; however Mental arithmetic and Written arithmetic algorithms were not significantly explained by the model. Test anxiety seems not to be a major problem in this sample; still, significant negative correlations were found, which likely might influence the pupils in some aspects.
