Warren County schools will begin the 2014-15 school year on Friday, Aug. 7. The School Board unanimously voted to adopt the calendar Thursday night.Noticeable changes include the removal of late-start days. Late-start Thursdays, where school started two hours late once a month, were added to the calendar this year to provide teachers with time to meet and discuss the new common core curriculum.Replacing late-start days are early release days, which are included four times throughout the year, Oct. 2, Dec. 4, Feb. 5 and March 5.On early release days, students will be released from school at 1 p.m. Teachers will remain at school for professional development until 3 p.m. These days are also stockpiled days.Another noticeable difference is days set aside for parent/ teacher conferences.
