The Chilton County Board of Education approved in a special meeting Tuesday a revised calendar for the 2012-2013 school year.

In accordance with a mandate from the Alabama Legislature, all county schools will start Monday, Aug. 20, no earlier than two weeks before Labor Day, and finish Thursday, May 23, no later than May 24, the Friday before Memorial Day.

The calendar includes 180 instructional days with six hours of instruction per day, with regular instructional days for students on parent-teacher conference day Oct. 29, Presidents’ Day in February and two weather days in the spring.

“We’re in compliance with all they’ve (the state) asked,” Superintendent Dave Hayden said. “If we need weather days, we’ll go on Saturdays, I guess.”

The board also approved Jemison High School principal Alan Thompson’s resignation.

In other business, Hayden confirmed that the school system will lose 7.38 teacher units because it had 118 fewer students this past year.

Schools will receive $31.35 per student for books, Hayden said.
