'Genetic factors influence over 60pc on academic success'

Genetic factors account for about 60 per cent of academic success, even after accounting for intelligence, finds a study.

For many years, research has linked educational achievement to life trajectories, such as occupational status, health or happiness.

But, the study explains that genes have substantial influence on academic success. The children were highly stable throughout schooling, meaning that most students who started off well in primary school continued to do well until graduation.

"Around two-thirds of individual differences in school achievement are explained by differences in children's DNA," said Margherita Malanchini, a psychology postdoctoral fellow at the University of Texas at Austin.

"But less is known about how these factors contribute to an individual's academic success overtime," Malanchini added.

However, that does not mean that an individual was simply born smart, researchers explained. Even after accounting for intelligence, genes still explained about 60 per cent of the continuity of academic achievement.

"Our findings should provide additional motivation to identify children in need of interventions as early as possible, as the problems are likely to remain throughout the school years," said Kaili Rimfeld, a postdoctoral researcher at the King's College London.

For the study, published in npj Science of Learning, the team analysed test scores from primary through the end of compulsory education of more than 6,000 pairs of twins.
