Fairfax County Public Schools elementary-age children will go to school five full days a week beginning in September, the FCPS board voted on Thursday.

The board voted 10-1 in favor of Superintendent Karen Garza’s proposal to eliminate early-release Mondays. Kathy Smith was opposed, saying that the board should wait for more discussion and implement it in 2015-16. One board member was absent from the meeting.

Fairfax County Public Schools have for decades released elementary school students 2 1/2 hours early on Mondays in order for teachers to have planning time. The “mini-Mondays” were generally unpopular with FCPS parents, who often had to scramble child care plans one day a week.

The new calendar changes how FCPS counts yearly instructional time. Garza proposed the change because allows for more snow days without making them up and also allows for more self-directed planning time for teachers.
