Lately, I’ve seen many people on the forums asking about their plans after finishing their Master’s degree, and some have mentioned wanting to pursue a PhD in Spain. Information on this topic seems a bit scattered. So today, I’m starting this thread to share what I know about the PhD system in Spain, primarily based on the regulations from the Royal Decree RD 99/2011. I hope this helps anyone who needs it.

How Long Does a PhD in Spain Actually Take?
This is the most common question. To put it simply, the duration of a PhD program in Spain is “flexible.” According to official regulations:
Full-time PhD: From the date of your initial enrollment, the standard duration is a maximum of 3 years. This is the ideal scenario, but most students need to apply for an extension. You can request 2 extensions: the first for one year, and a second for another year. Therefore, a full-time PhD can take up to 5 years in total.
Part-time PhD: If you are working or have other commitments, you can opt for part-time studies. For this mode, the maximum duration is 5 years. Similarly, you can also apply for extensions, allowing the program to last up to 8 years.
Most supervisors and academic committees are quite understanding. As long as your research is on track, extension requests are generally approved. But remember, procrastination is the ultimate enemy of a PhD student!
Application Requirements and Key Factors
The formal requirements for a PhD in Spain aren’t overly strict. Typically, you need an official Master’s degree, and the combined credits from your Bachelor’s and Master’s degrees must total at least 300 ECTS. However, the truly crucial elements are your research proposal and your supervisor. Without a supervisor’s approval to accept you, everything else is moot. Therefore, the PhD application process is essentially about contacting and building a rapport with potential supervisors. Regarding language, while many STEM programs accept English, proficiency in Spanish will significantly broaden your options and facilitate smoother communication with your supervisor.
A PhD program isn’t just about attending classes and then writing a dissertation; its core is independent research. Here’s a table outlining the main tasks throughout the years of a PhD program:
| Phase | Main Tasks | Notes |
| Year 1 | Enrollment, refining the research plan, taking a few methodology courses, conducting a literature review | The key is to get your research plan approved by the academic committee. |
| Years 2-3 | In-depth research, experiments, data analysis, writing and publishing academic papers | This is the core stage of doctoral research, evolving from the initial PhD application to a Spanish university. Regular progress reports to your supervisor are required. |
| Final Year | Writing the doctoral thesis, revisions, and preparing for the defense | Once the thesis is complete, it requires the supervisor’s signed approval before it can be submitted to the university for defense. |
Spain’s doctoral training system is well-regulated and mature. The academic atmosphere here is relatively liberal, and the cost of living is quite low compared to other parts of Europe. If you genuinely want to dedicate yourself to research, Spain is an excellent choice.
