New study sheds light on twins' class riddle

TWINS who share a classroom will do just as well academically as twins placed in separate classes, new research shows, helping resolve a dilemma many parents of multiple children face.

Parents of twins, triplets and others often wonder whether it'd be better for their children to attend the same class or if they would benefit more from being separated.

The study, by VU University of Amsterdam biological psychologist Tinca Polderman and her colleagues, concluded there should be no blanket recommendation. "Classroom placement of twins should be based on each family's needs individually," she said.

So far, three studies have looked at effects among twins of separation in primary school, the researchers said in the study, published in the Journal of Epidemiology and Community Health.

Two studies found separated twins were at greater risk of depression and anxiety, although the effects were small. For the Dutch study, researchers tracked 839 identical and 1,164 fraternal twin pairs between 3 and 12 years.

Seventy-two percent had shared a classroom all the time, 19 percent were in the same school but different classes and 9 percent shared a classroom for some time.

Initial results showed twins who were in the same school but in different classes scored slightly higher on a standard test typically given to Dutch children in the eighth grade than those in the same class.

But when the researchers controlled for socioeconomic status and behavioral issues, there was no big difference.
