How genes can influence children’s exam results

Eva Kraphol & Kaili Rimfield:

The idea that children can inherit the ability to get good results at school can spark heated debate. But, put simply, all this means is that children differ in how easy and enjoyable they find learning and that these differences are to a large extent explained by differences in their genes, rather than differences between schools or teachers.

We know from previous research that educational achievement in primary, middle school years and at the end of compulsory education is highly heritable. Heritability is a population statistic – it doesn’t tell us anything about a single individual. It describes the extent to which differences between children can be put down to DNA differences, on average, in a particular population at a particular time.
