Abstract

Data from an epidemiological sample (n= 1206) of British schoolchildren were used to estimate the proportions of 9- to 10-year-olds with specific arithmetic difficulties (SAD), combined with arithmetic-and-reading difficulties (ARD), and specific reading difficulties (SRD). Children in the sample contributed scores on saparate tests of arithmetic reading and nonverbal intelligence. Using a cutting-store approach, which took into account performance on all three tests, a small group of children with SAD (1.3 %) were distinguished from tarter groups with ARD (2.3%) and SRD (3.9%). Contrary to some previous reports, there were equal numbers of males and females within each of the two groups with arithmetic difficulties but a preponderance of males over females amongst the group with specific reading difficulties.
