Traditional vs. Modified
The pie charts below compare the distribution of instructional days and days out of session on the nine-month traditional calendar vs. the distribution of school days on a balanced or modified calendar. Weekends are excluded from the charts, with both models represening a standard school year of 180 days.
The traditional calendar features a summer vacation of 12 weeks followed by an extended period of
instructional days, with the first break coming at Thanksgiving. The winter holidays are followed by 55 instructional days before a short spring break. Spring break is followed by 40 instructional days before the end of the school year.
The balanced calendar reduces the long summer break and simply apportions those days throughout the school year, producing more frequent breaks and thus limiting long periods of in-session days, as well as longer vacations. Both calendars feature 180 days of instruction, with the modified calendar balancing the frequency of in-session days with days on break. The winter break and Thanksgiving break can be the same on both calendars.
