Frequently Asked Questions
What are the chances of getting into Stanford CS PhD program if I am an international student?
It's very competitive and a few people qualify each year. In addition to good grades, the admissions staff reads closely into your research interests and whether you are interested in the same areas as a faculty member. A strong research experience and well-written recommendations are key.
Is a Masters required for application?
Not always. The PhD is a direct entry qualification for students having good research background, many of whom may go directly to the PhD after completing a bachelor's degree. It is important to be able to do original research, not so much the master's degree you have or don't have.
Are the PhD students in CS funded at Stanford?
Fully funded – usually tuition covered plus a living stipend, often through assistantships or fellowships – are offered to students who are admitted to the PhD program. An amount and terms will vary; please check funding information on the official department page.
Is there a prerequisite that must be met before I sign up?
Sometimes it is not strictly necessary, but it is very useful to know whose research interests you are interested in. Be specific about faculty and labs to make a point to the committee. Some applicants write polite applications, but a quality, well focused application is most important.
Do they need a GRE for the CS Ph.D.?
Some CS policies have undergone significant changes in recent years and may be optional or not be required. Please be sure to verify the current requirement in the official Stanford Computer Science admissions page before you make your scores.
What is the duration of the PhD?
The average time for most students is 4-6 years depending on their research field and progress. You'll have to write a dissertation and defend it after several years of intensive research, and you will need to meet some standards along the way, such as early coursework.
Is the Stanford CS PhD Right for You?
The Stanford PhD in Computer Science is designed for students who wish to engage in research and contribute to the development of new knowledge, rather than rely on existing resources for new applications.
