Danish researchers have found that twins are performing on par with other children from single births for the first time. Previously the performance of the twins has been found wanting and they fared less better than other average students. Researchers felt this was because twins receive less attention from parents as well as have low educational motivation.

The Danish study of 11,000 youngsters shows that twins are catching up. "We interpret our findings as indicating that improvements in obstetric and pediatric practices over the past 50 years have largely ameliorated the cognitive disadvantage identified in twins by earlier research, despite more twins of extremely low birth weight now surviving the first year of life," said lead researcher Professor Kaare Christensen.

Researchers identified 3,411 twins and 7,796 singletons who were born in Denmark between 1986 and 1988. This data was obtained from the Danish national birth register. The researchers tabulated information like birth weight, gestational age at birth, and parents' age and education.
