Harvard University offers doctoral programmes across multiple schools, each with distinct requirements and traditions. Whether you're pursuing a PhD through the Graduate School of Arts and Sciences (GSAS) or a professional doctorate through Harvard Business School, Law School, or other faculties, this guide will help you navigate the dissertation process.
Harvard's Doctoral Landscape
Harvard's doctoral ecosystem is complex. The Graduate School of Arts and Sciences (GSAS) awards the PhD in arts, humanities, social sciences, and natural sciences. Professional schools offer their own doctorates: the DBA at Harvard Business School, the SJD at Harvard Law School, the EdD and PhD at the Graduate School of Education, and the DrPH at the School of Public Health.
Each programme has unique requirements, but common elements include comprehensive examinations, prospectus approval, supervised research, and a final defense. This guide focuses primarily on GSAS requirements, with notes on professional school variations.
Qualifying Examinations
Before beginning dissertation work, Harvard doctoral students must pass qualifying examinations (often called 'generals' or 'prelims'). The format varies dramatically by department:
- Humanities: Often involve written exams on reading lists plus an oral examination
- Social Sciences: May include field exams, methods exams, and teaching requirements
- Natural Sciences: Typically include an oral qualifying exam on research proposal
Most departments require qualifying exams by the end of Year 2 or 3. Passing qualifies you for 'ABD' (All But Dissertation) status and allows you to focus on dissertation research.
Preparation tips:
- Start preparing 6+ months in advance
- Form study groups with cohort members
- Request past exams from your department
- Schedule regular meetings with committee members
Developing Your Prospectus
The dissertation prospectus is a detailed research proposal submitted after passing qualifiers. A strong Harvard prospectus typically includes:
- Research question: Clear, focused, and significant to your field
- Literature review: Demonstrating command of relevant scholarship
- Theoretical framework: The conceptual lens guiding your analysis
- Methodology: Detailed research design and methods
- Chapter outline: Proposed structure with brief descriptions
- Timeline: Realistic completion schedule
- Bibliography: Comprehensive list of sources
Prospectus length varies—humanities proposals may run 30-50 pages, while sciences may be shorter. Your department holds a prospectus meeting where your committee evaluates and approves your plan.
Your Dissertation Committee
Harvard dissertations are supervised by a committee typically comprising:
- Primary Advisor: Your main supervisor and intellectual guide
- Second Reader: Another faculty member providing regular feedback
- Additional Members: Usually 1-2 more faculty (may include scholars from other universities)
Choose committee members strategically. Consider:
- Expertise alignment with your research
- Advising style and availability
- Career connections in your target field
- Diverse methodological perspectives
Build relationships early—attend office hours, take courses with potential advisors, and seek feedback on preliminary work.
The Writing Process
Harvard dissertations don't have a universal length requirement, but norms exist:
- Humanities: 200-400 pages (80,000-120,000 words)
- Social Sciences: 150-300 pages (60,000-100,000 words)
- Natural Sciences: Often shorter, with emphasis on publications
Many Harvard programmes now accept three-paper dissertations, especially in economics, psychology, and sciences. These compile three publishable papers with an introduction and conclusion.
Writing strategies:
- Write regularly—aim for daily or near-daily writing sessions
- Join or form a dissertation writing group
- Use Harvard's writing resources (Writing Center, Dissertation Completion Fellowships)
- Submit chapters to your advisor regularly, even if imperfect
The Dissertation Defense
The final defense (called the 'dissertation exam' at Harvard) involves:
- Presenting your research to your committee (usually 1-2 hours)
- Responding to questions and critiques
- Demonstrating mastery of your field and methodology
- Defending your original contribution
Unlike some universities, Harvard defenses are typically not public—only committee members attend. The committee deliberates privately and announces one of three outcomes:
- Pass: Dissertation accepted, pending minor revisions
- Conditional Pass: Significant revisions required before final approval
- Fail: Rare, and usually signalled well before defense
Most students who reach defense pass—your committee wouldn't schedule it otherwise. Prepare by re-reading your dissertation, anticipating questions, and practicing your presentation.
Professional School Requirements
Harvard Business School (DBA):
The DBA is a research doctorate with rigorous methodology requirements. Expect coursework in Years 1-2, qualifying papers, and a dissertation comprising three empirical papers.
Graduate School of Education (EdD/PhD):
The EdD emphasizes practice-oriented research; the PhD focuses on scholarship. Both require qualifying papers, a dissertation proposal, and final defense.
Law School (SJD):
The SJD (Doctor of Juridical Science) requires a prior LLM and involves a major dissertation on legal scholarship.
School of Public Health (DrPH):
The DrPH emphasizes leadership in public health practice. Requirements include integrative experience, qualifying exams, and a doctoral dissertation or project.
Timeline and Funding
Typical Harvard PhD timeline:
- Years 1-2: Coursework, language requirements, teaching
- Year 2-3: Qualifying examinations
- Year 3-4: Prospectus development and approval
- Years 4-6: Dissertation research and writing
- Year 5-7: Completion and defense
GSAS guarantees funding for most PhD students (typically 5 years), including tuition, health insurance, and stipend. Additional years may require external fellowships or teaching.
