Tuesday marked the third snow day for students in Clay Community Schools.
Officials with CCS decided to cancel school Tuesday after road conditions worsened throughout the morning.
"We got a lot of black ice out there," CCS Director of Transportation Frank Misner said. "It's just a little too slick out there."
Misner said the corporation had originally called for a two-hour delay. But continual sleet kept falling, forcing the cancellation.
"It just didn't get any better for us," Misner said.
Misner said the decision to cancel school Tuesday was made before 8 a.m.
According to the Indiana Department of Education, a calendar year for school consists of 180 days.
CCS has already had two snow days. Tuesday's cancellation was the third so the school year could end on May 23. The original last day for school was May 22.
The corporation has two built-in snow days based on discussion between the school board and teacher's association.
According to Clay Community Classroom Teacher's Association Representative Russ True, both the teacher's association and school board negotiate the school calendar on an annual basis. Snow days are part of the calendar.
True estimated the corporation has built in two snow days for at least 15 years.
"More than likely, that would be the normal outcome, to tack it on at the end," True said of the prospect of adding the snow day at the end of the year.
According to school officials, all extracurricular activities were also canceled per corporation policy.
Both Clay City and Northview High School boys' basketball teams had games scheduled for Tuesday as the Eels were scheduled to face Linton at home and the Knights were set to face Greencastle, also at home.
