Students at a Wilmette school are breaking records, but it has nothing to do with academics.
Highcrest Middle School set the world record for most twins in a single grade. There are 23 sets of twins in the 5th grade -- nearly ten percent of the class!
It shatters the old record of 16 sets.
School officials say several factors play into the twin boom including: post 9/11 families wishing to start their families and the advancement of fertility treatment.
