9th and 10th Grade Core Curriculum
As a D-E Upper School student, you can… Build an Upper School experience that’s truly your own — starting with a strong academic foundation and growing into real choice, depth, and independence.
Foundational Knowledge
- Students build a strong, foundational academic base in their first two years. They learn how to think critically, communicate effectively, and problem-solve. This foundation ensures that every student enters the upper grades ready to take on advanced coursework with the skills and confidence.
Math & Science
-
Most high schools divide math into isolated courses. Our Integrated Math & Modeling sequence blends Algebra, Geometry, and other topics rather than teaching each as a completely separate subject. The course is problem-based and student-centered—students learn through problem sets and discussions with their peers.
-
The Integrated Biology & Chemistry course brings the two sciences together and demonstrates how they interconnect.
-
Students develop connections across topics and disciplines, not just mastery of isolated units. They work together collaboratively, discuss strategies, and practice articulating their reasoning. They become more confident tackling unfamiliar problems because they have built the foundation to be good mathematicians.
Human-Development Courses
-
Students take Global Literacy in 9th grade and Positive Psychology in 10th grade
-
Global Literacy allows students to engage in an exploration of themselves, their identities, and their communities. Students learn how to talk across differences and engage thoughtfully with others.
-
Positive Psychology helps students understand their own brains and emotions and empowers them with strategies and tools to support their own mental health.
Discussion-Based Learning
-
One of the most distinctive aspects of D-E’s Upper School is the commitment to discussion-based classrooms. Across all departments, students sit around tables, Harkness-style, and engage in dialogue, not lecture. They practice listening closely, building on peers’ ideas, learning how to disagree with others. They learn to question, challenge, or refine their own thinking. Students understand that their voice and perspective matter, making them more confident communicators.
Explore life beyond the classroom — balancing rigorous academics with athletics, arts, leadership, and service.

Prepare to ‘meet the challenges of a changing world and make it better’!
Developing 'Whole-Souled Citizens'
Our entire program in the US is grounded in our mission statement—to meet the challenges of a changing world and make it better.
What this looks like in the classroom will differ from department to department and year to year. One consistency, however, is that in our classrooms students are learning how to advocate for themselves, collaborate with others, take thoughtful risks, and communicate effectively.
In the process of building these durable skills, students build community and in doing so, a sense of themselves as well as a sense of belonging. In any space where teachers prioritize student voice and choice, innovation and discovery will be present—whether this is in a Math class where students are collaborating on a difficult problem or a History class in which students are presenting on the historical moments that shape and define our current lives.
