How Long Does It Take to Complete a PhD Dissertation?

Many students, especially those in the early stages of their PhD journey, often ask how long the process of completing a PhD dissertation typically takes. In this article, we explore the steps involved, the typical timeframes, and share insights from personal experiences to provide a comprehensive understanding of the PhD dissertation process.

Introduction to Thesis and Dissertation

A thesis is a requirement for obtaining a Master’s degree, while a dissertation is the primary requirement for earning a Doctoral degree. The length and duration of dissertation preparation can vary significantly depending on the discipline and individual circumstances. In the field of science and engineering, the process might take longer compared to liberal arts degrees.

Perspectives on Dissertation Completion

From my own experience, I began working on my dissertation during mid-1975 and had a complete draft by fall 1976. However, due to unforeseen circumstances, such as my father’s passing in late 1975, I was compelled to join the workforce full-time to support my widowed mother. After completing all required coursework, it took me about two years before graduating in December 1977. Interestingly, some of my fellow students who had independent incomes could take as long as six years to complete their dissertations after finishing their required coursework.

Creating a PhD Thesis

A PhD thesis is not something one “takes;” rather, it is something one creates. Imagine a Masters thesis that is roughly about twice as long and more complex in its requirements. A well-prepared thesis can take approximately two years and involves several rigorous processes:

Selecting a topic Submitting and having a proposal accepted Coming up with an outline and having it approved Writing the actual thesis Seeking feedback from advisors and making revisions

Given the complexity and the need for thorough review, it’s essential to allocate a minimum of two years, with the possibility of requiring more time depending on individual circumstances.

Dependency on Institution and Circumstances

Ultimately, the duration of your PhD dissertation strongly depends on your institution and personal circumstances. In the UK, for instance, full-time students have a finite period of time allocated, typically around four years. However, the days of extended periods of research and writing are gradually coming to an end.

Personal Experiences and Advice

After extensive research and with my first draft complete, I left the dissertation sitting on my desk for a year while I conducted additional research on the second part of the project. After a few hours of reviewing the initial draft, my advisor advised, “Jonas, no one can read this.” This feedback required me to spend approximately half a year writing to make the content readable, and an additional few months to get it to an acceptable stage where my advisor could sign off on it, much to my relief. Upon further review, the advisor recommended dropping the second part, which could have potentially saved me a year. Reflecting on this experience, it highlights the importance of thorough preparation and feedback loops throughout the dissertation process.

In conclusion, while the general timeframe for completing a PhD dissertation varies, careful planning, active engagement with advisors, and meticulous attention to detail are key to a successful and efficient process. Whether it takes two years or more, the journey to completion is an integral part of the PhD experience.
