The current study is a pilot test of a screening instrument aimed at flagging children at-risk for dyscalculia. The screening test is designed so that it can be applied by any teacher with minimal instruction and financial investment and it is based on Number Sense battery, NUCALC battery and, first of all, romanian mathematical curriculum. Out of the 45 students from Bucharest (8-11 years) participating in this study, ten scored under the cut-off point of 10, three of which scored under 5. All these children, deemed at risk for dyscalculia, scored above the threshold for mental delay on two IQ tests.
