School Calendar Guidelines and Notes:
State law requires that students are in school 180 days or its equivalent. Each year, school districts are given four “emergency days” they can use for a variety of purposes. Many districts have been building those days into their calendars.  In Cobb County, there are 178 days scheduled for students, and 188 days scheduled for teachers.  The first semester includes 88 school days and ends prior to Winter Holidays.  Second semester includes 90 school days, and ends prior to Memorial Day.  Fall Break begins on the fourth Monday in September.  Winter Break begins on the third Monday in February (Presidents Day).  Spring Break begins on the first Monday in April, providing consistency with other metro school systems.  The school year ends on a Wednesday to provide enough time to schedule graduation ceremonies.
