Can a DNA test reveal how well your child will do at school? Scientists pinpoint genes that could predict human intelligence

A child's performance at school is widely considered to be a complex combination of inherited ability, the way they were brought up, the quality of teaching they received and a bit of luck. But a new study has suggested it may be possible to predict a person's academic achievement by looking at their DNA alone. Researchers have developed a new genetic scoring technique that explains almost 10 per cent of the differences between children's educational attainment by the age of 16-years-old. A DNA test could soon be used to predict how a child will do when they are at school after researchers found they can explain 10 per cent of a person's academic achievement by the age of 16-years-old by creating what is known as a polygenic score based on 74 genetic variants thought to play a role in educational performance The IQ test has long been dismissed as an inaccurate way to discern how intelligent a person really is - but now scientists may have found a better way. Researchers at the University of Warwick say MRI scans can measure human intelligence, and define exactly what it is.
