Frequently Asked Questions
Answers to common questions about the dissertation and thesis process.
The dissertation and thesis process raises a lot of questions – and that is completely normal. Below you will find answers to the questions we hear most often from graduate students at every stage of their journey. If your question is not listed here, explore our stage-by-stage guides or visit Subthesis.com for interactive research tools.
How long does it take to write a dissertation?
Most doctoral dissertations take 1-3 years to complete after coursework, though timelines vary by program, methodology, and personal circumstances. A realistic timeline includes topic selection (1-3 months), literature review (3-6 months), proposal and IRB (2-4 months), data collection (3-12 months), analysis and writing (6-12 months), and defense preparation (1-2 months).
What is ABD and how do I avoid getting stuck?
ABD stands for 'All But Dissertation' -- a student who has completed all doctoral requirements except the dissertation. Many students stall at this stage due to isolation, perfectionism, or lack of structure. The key to avoiding the ABD trap is maintaining momentum through consistent writing habits, regular advisor meetings, and peer accountability.
What is the difference between a dissertation and a thesis?
A dissertation is typically required for doctoral degrees (PhD, EdD, etc.) and involves original research that contributes new knowledge to the field. A thesis is usually required for master's degrees and may involve original research or a comprehensive analysis of existing literature. The structure and length differ, but the process stages are similar.
Do I need IRB approval for my dissertation?
If your research involves human subjects in any way -- surveys, interviews, observations, or use of existing data about identifiable individuals -- you will likely need IRB review. Even studies that seem low-risk typically require at minimum an exempt review. Check with your university's IRB office early in your process.
How do I choose the right dissertation topic?
A good dissertation topic sits at the intersection of your personal interest, a gap in the existing literature, feasibility (data access, timeline, resources), and alignment with your program requirements. Start by reviewing your coursework interests, talking with your advisor, and exploring recent literature in your field.
What should I expect during my dissertation defense?
A typical dissertation defense involves a 20-40 minute presentation of your research followed by 60-90 minutes of questions from your committee. Most defenses result in a pass with minor revisions. Preparation is key -- practice your presentation, anticipate questions, and remember that you are the expert on your specific research.
