WINNETKA, IL (WLS/CNN) -- They're seeing double a lot at New Trier High School, especially in the sophomore class.
So much so that they have set not one, but two Guinness World Records – “most twins” and “most multiples in a single academic year at one school.”
There are 44 sets of twins and one set of triplets.
That means about 10 percent of the sophomore class is made up of multiples.
When they were freshmen, they reached out to the folks at Guinness. After about a year-and-a-half, it was officially certified.
With 45 sets of multiples in a single academic year, New Trier shattered the previous record of 24 sets held by Highcrest Middle School in Wilmette, IL.
It was the Novosel twins, Luke and Ryan, who noticed the coincidence when they were students at Highcrest.
"We knew we had another record coming in to New Trier," Luke said.
The Novosels knew that once they reached high school, their record-setting group would join more sets of multiples from the five other elementary districts that feed into New Trier.
In a class of just over 1,000 students, this group of 91 exceeds the national average for multiples by nearly three times.
"I just don't think that being a triplet is very different to twins,” triplet Anna Hinrichs said. “There's just one extra."
But why so many multiples in this class?
Some factors for these twins could be age of their moms and access to fertility treatments.
