Upper School Schedule

Calhoun’s innovative Upper School schedule allows students to delve deeper into subjects and explore their passions.

We divide the year into terms called “mods.” Students take fewer classes in each term that meet for longer periods of time. We also operate on a six-day rotation with daily blocks. With this structure, the school avoids missing a day of classes when a holiday occurs.

Upper School students complete required courses in English, math, science, social studies and world languages. The schedule also allows for students to take a wide variety of electives in any subject. In twelfth grade, students have the opportunity to customize their schedule and go deeper in core subjects and areas of interest.

Upper School Schedule Highlights

  • Students spend more time throughout the school year in their core classes, while also having time to pursue their passions and interests.
  • Students are able to explore fewer subjects at a time in greater depth, enabling greater understanding and retention.
  • Students have more time in the day to meet one-on-one with teachers, gather at clubs or town meetings, or work on projects with their peers.
  • Faculty have more time to design innovative lesson plans and use the city as a classroom in their teaching.

“Calhoun's schedule prepares students for a life of independence after [high school]. Students are making crucial choices about their education starting in ninth grade, and that degree of choice increases as they progress through the Upper School”

Jarrad Nunes, Co-Director of College Counseling

Community Time

Community Time is a dedicated period each day when students are free to connect, meet with clubs or teachers, and attend regular Town Meetings. During Town Meetings, the community gathers to talk about important issues, hear from guest speakers, or showcase their talents.


Every day Upper Schoolers meet with their cluster, a group of students and one or two advisors that acts as a homebase for announcements and support. Cluster is one way that community building and support is woven into the daily Upper School experience.
