A class of 24 twins.

A school broke a world record by having 24 sets of twins.The middle school in Illinois has the most sets of twins in a single grade. They discovered the fact when twin boys Luke and Ryan Novosel, both 11, began counting up all the other twins in their Highcrest Middle School directory, in Wilmette, Ill. “We were absolutely shocked,” said their mother, Nancy Fendley. “It’s blowing it away,” she added.With some help from mom and dad, the boys submitted an application with Guinness earlier this year and after following up with birth certificates, photos and proof that all are enrolled at the school, they are to receive official recognition in several weeks.Most of the twins, who are mostly fraternal are three sets of boy-boy twins, 11 sets of girl-girl twins and 10 sets of boy-girl twins. The two sets of identical twins are girls. They are all in their fifth grade.“I think it’s just statistically kind of bizarre,” Fendley said.Three schools share the current record of 16 pairs of twins in one grade; Valley Southwoods Freshman High School in West Des Moines, Iowa; Staples High School in Westport, Conn.; and Maine South High School in Park Ridge, Ill.Federal statistics show about 33 twins per 1,000 births in 2010.“The whole school thinks it’s the greatest thing, It’s been such a fun, creative experience,” Fendley said.
