No need for more labels, just good teaching
As with dyslexia, there is no national or international protocol for the diagnosis of dyscalculia ("Ministers accused of failing maths 'dyslexics'", 27 May).
Children with poorly developed spatial ability struggle with numeracy and mathematics. So developing children's spatial ability through the curriculum and parental involvement is likely to enhance their achievement in numeracy and mathematics.
The technically able, though not necessarily the linguistically bright, child is typically good at maths (and science). Such children usually have a measure of spatial functioning well in advance of their verbal or linguistic ability.
Understanding children's general and specific learning difficulties and working together to resolve them is what is required. Education does not need any more labels to account for underachievement.
