How to Get a PhD
Getting a PhD involves a multi-year academic journey characterised by rigorous research training, independent project execution, and scholarly writing. The process requires identifying a novel research question, securing a supervisor and funding, conducting extensive investigations, writing a substantial doctoral thesis, and successfully defending it in a viva voce examination.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
The Preparation and Application Phase
The journey to a PhD begins long before enrolment. Prospective students must identify their research interests and draft a research proposal outlining their proposed project's scope, methodology, and significance. A critical step is finding a potential supervisor—a faculty member whose expertise aligns with the project. Candidates must contact these academics, secure their support, and then submit a formal application. This application includes academic transcripts, letters of recommendation, a statement of purpose, and proof of funding, which may come from university scholarships, research councils, or external sponsors.
Coursework, Candidacy, and the Research Phase
Once admitted, the first year or two varies by region. In North America, students undertake coursework and must pass comprehensive or qualifying exams to advance to PhD candidacy. In the UK and Europe, students focus on research immediately, under a probationary status that is upgraded to full PhD status after a successful first-year review. The core of the PhD involves executing the research plan. This entails conducting laboratory experiments, field work, archival research, or mathematical modelling, followed by data analysis and writing papers for publication under the supervision of a thesis committee.
Thesis Writing and the Viva Voce Defence
The final stage of the PhD is writing the doctoral thesis (or dissertation), which is a book-length manuscript detailing the research questions, methodology, results, and conclusions of the project. The thesis must demonstrate that the candidate has made a significant, original contribution to their field. Once approved by the supervisor, the thesis is submitted to a panel of examiners. The candidate must then defend their work in an oral examination, known as a viva voce. Passing this exam, often subject to minor or major corrections, is the final hurdle to graduating with a doctorate.
Key facts
At a glance
- A PhD requires securing a faculty supervisor and demonstrating research feasibility.
- The first phase involves literature review, proposal writing, and passing qualifying exams.
- The core phase is dedicated to independent data collection, analysis, and academic writing.
- Candidates must compile their findings into an original, peer-reviewed doctoral thesis.
- The final requirement is passing an oral defence (viva voce) evaluated by external examiners.
Common misconceptions
What people often get wrong
Often heard: Getting a PhD is just like being a student for a few more years.
Actually: A PhD is more akin to an apprentice research job. The focus is on producing work, not consuming lectures and passing tests.
Often heard: You must pay for a PhD out of pocket.
Actually: Most reputable universities offer full funding packages (stipends and tuition waivers) for doctoral candidates, especially in STEM and social sciences.
Often heard: You must know everything about your topic before you start.
Actually: A PhD is a training programme. While you need a solid foundation, the entire point of the degree is to learn how to research and discover new insights as you go.
