Dartmouth's D-Plan Explained: How the Quarter System Works and Why It Matters

Key Takeaways

  • Dartmouth's D-Plan divides the year into four 10-week quarters — fall, winter, spring, and summer
  • All students are required to be on campus for freshman fall and sophomore summer
  • Off-campus terms allow students to pursue internships, research, or study abroad without missing classes
  • The D-Plan requires advance planning but creates unique flexibility not available at semester-based schools
  • Sophomore summer is one of the most beloved Dartmouth traditions — a uniquely tight-knit experience
Dartmouth's D-Plan is a quarter-based academic calendar with four 10-week terms per year. Students typically take courses in three of the four terms and use their remaining term for internships, research, or study abroad. All students must be on campus for freshman fall and sophomore summer. The D-Plan creates distinctive scheduling flexibility and a uniquely staggered campus experience — you will be on campus when some classmates are away, which constantly refreshes the social community.

The D-Plan is one of the most distinctive features of a Dartmouth education. If you're considering Dartmouth, understanding how it works — and how to use it well — is essential.

The Basics of Dartmouth's Quarter System

Dartmouth divides the academic year into four 10-week terms: fall (September–November), winter (January–March), spring (March–June), and summer (June–August). Students typically enroll in three terms per year and take one term as an "off term." Because the terms are shorter than a typical semester, Dartmouth courses move quickly — there's less time between exams and assignments, and the pace is intense.

Required Terms on Campus

All Dartmouth students must be on campus for freshman fall (your first term) and sophomore summer. Sophomore summer is legendary — it's the one term when the entire sophomore class is on campus together without seniors (who have graduated) or many other upperclassmen. The result is an unusually tight-knit, community-focused experience that Dartmouth students consistently describe as one of their favorite memories.

How Students Use Off-Campus Terms

The D-Plan's off-campus terms are where much of Dartmouth's career-building happens. Students use them for: internships at companies and organizations across the country and world, research fellowships, study abroad programs, or personal projects. Because you can schedule an off term in any of the four seasons, you can intern during a fall or spring semester when other students are in class — giving you access to opportunities that aren't just limited to the summer competition window.

Planning Your D-Plan

The D-Plan requires advance planning, especially around which terms you'll take off and how that affects your course sequencing for your major. Dartmouth provides D-Plan planning resources and advisers, and most students figure out their four-year plan in the first year. The planning process is itself a useful exercise in thinking about your priorities.

Frequently Asked Questions

Can I choose which term to take off at Dartmouth?
Yes, within constraints. All students must be on campus for freshman fall and sophomore summer. Beyond those requirements, you work with your adviser and registrar to schedule off terms that work with your major requirements and personal goals.
Is the D-Plan better for internships than a regular semester school?
Many students think so. The ability to do an off-campus term in the fall or winter — when other students are in class — means you can pursue internships during less competitive windows. Finance and consulting internships in particular are often easier to land in non-summer terms.
Is the quarter system harder than the semester system?
The quarter system moves faster — 10 weeks instead of 16 — which means less time to recover from a slow start. Many students find the pace invigorating; others find it stressful. If you tend to start slowly and build momentum, the quarter system requires adjustment.
