A PhD in USA takes approximately 5 – 6 years of full-time study and can cost between $12,000 – $45,000 per academic year. PhD programs in USA differ from that in the UK and Europe in that students must first take taught classes, coursework and exams before starting their research project.
Why Do a PhD in USA?
The United States has long had some of the most distinguished universities and advanced PhD programmes in the world. Combined with curriculum flexibility, rigorous teaching methods, vast funding opportunities, breathtaking campuses and significant career prospects, it’s no wonder that it is one of the most sought-after study destinations for research students.
In addition to comprehensive training standards, here are a few other reasons why a student may choose to undertake their PhD in the United States:
- Longer learning timeframes – A PhD in the US lasts longer than a PhD in the UK or Europe. This allows students to more confidently transition from undergraduate to postgraduate studies; more commonly referred to as ‘graduate studies’ in the US. This gives you the opportunity to learn more about your subject, research methods and academic writing in general before starting your research project.
- World-class universities – It’s no secret that some of the most well-known higher education institutions that continue to dominate global rankings are based in the United States. Although many factors go into determining whether a position is right for you, a PhD at a high-ranking American university will undeniably have many benefits, from excellent learning standards to access to innovative equipment and deep expertise.
- International network – The US has long been a popular choice among PhD students around the world. As such, the US hosts a diverse and multicultural learning environment in which many research students will quickly feel at home.
- Opportunities – With over 4,000 universities in the US, we can safely say you will have plenty of opportunities to find the ideal combination of project, supervisor and university that works for you.
Universities in USA
Universities in the United States can be divided into two types: public universities and private universities.
Public universities are financed by the state in which they are based. Because of this, public universities charge less for students from within the state and more for students from outside the state, including international students.
Private universities are not financed by their state, but by private donors, research funds and tuition fees. For this reason, private universities generally charge higher tuition fees than public universities and require all students to pay the same amount, regardless of whether they come from out-of-state or abroad.
According to the Times Higher Education World University Rankings 2021, eight of the top ten universities in the world are located in the United States. These are:
|1||UK||University of Oxford|
|4||USA||California Institute of Technology|
|5||USA||Massachusetts Institute of Technology|
|6||UK||University of Cambridge|
|7||USA||University of California, Berkeley|
|10||USA||The University of Chicago|
Method of Study
The main difference between a PhD in the US and a PhD in Europe lies in the program structure. Whereas a European PhD essentially consists of a single phase lasting three to four years, an American PhD consists of three different phases, each with its own time frame.
- Phase One – The first phase lasts approximately two years and focuses on building a basic foundation for the doctoral student. This phase consists largely of taught components such as lectures, tutorials and laboratory sessions, in which the student learns more about theoretical concepts and research methods within their discipline.
- Phase Two – The second phase can be considered an assessment phase, which runs both periodically alongside and at the end of the first phase. Here, students complete coursework and take exams on the basis of the material they have covered of which they must pass in order to proceed to the third phase.
- Phase Three – The third phase lasts approximately three years and resembles the European PhD structure. During this period, the student undertakes an independent research project, including forming a research design, conducting experiments, writing a thesis (more commonly referred to in the USA as a dissertation) and sitting a viva exam.
Besides structure, a key difference between a PhD program in the US and in Europe is the focus on teaching requirements. In the US, doctoral students are expected to lecture, lead tutorials, host laboratory sessions, mark coursework and provide office hours for undergraduate students. Although students studying in European will likely contribute to these at some point during their study, this would normally be on a voluntary basis and involve less time commitment.
Another difference is project flexibility. In Europe, students typically apply to a PhD project predetermined by a supervisor, and although there may be some scope to adapt the project, depending on the funding provider, it will usually be limited to how the project is carried out rather than what it is about. In the US, however, a student applies to become a doctoral candidate within a department rather than applying for a particular research project. This is because students are expected to decide on their thesis topic (also commonly referred to as a dissertation research topic) near the end of their first phase after they have developed a better understanding of their subject and know where their interests lie. Therefore, research students in the US generally have more flexibility and influence in the direction of their research than students in the United Kingdom or Europe.
PhD Admission Requirements in USA
PhD admission into US universities can be highly competitive, both because of the limited number of positions and the large number of annual applicants.
The eligibility requirements for a doctoral program in the USA can generally be divided into four sections:
- Grade Point Average (GPA) – in the US, a scoring system known as Grade Point Average is used to measure academic ability. A student’s GPA is calculated as a weighted score of the subjects they study during their undergraduate degree; an equivalent score is calculated by universities for international applicants. Although universities rarely set minimum GPA requirements for doctoral study, it’s worth being aware that a GPA of 3.0 is equivalent to a UK second class honours (2:1); the typical entry requirement for UK universities.
- Graduate Records Exam (GRE) – most universities will require you to take a series of examinations known as Graduate Records Exams, which are used to determine your suitability for graduate study. GREs will assess your analytical, reasoning and critical thinking skills as well as your depth of your subject.
- Student aptitude – in addition to academic ability, US universities also look for characteristics of a strong researcher. These include traits such as engaging in the subject in your own time, e.g. by attending talks and conferences, demonstrating a high degree of independence and enthusiasm, and a general passion for your subject.
- English Language Proficiency – international students whose first language is not English must sit language exams such as IELTS or TOELF to demonstrate their English language proficiency.
International students will also require a F1 student visa in order to study in the US, however, you would typically apply for this after you have secured a place into a doctorate program.
How to Apply for PhD in USA
When applying for a PhD position at a graduate school, the application process will differ between universities, however, they will all typically ask for the following:
- Academic CV – a short document summarising your educational background and current level of experience.
- Personal statement – a document which outlines why you believe you are suitable for PhD study and your passion for the subject.
- Academic transcripts – a complete breakdown of the modules and their respective marks you have taken as part of your previous/current degree.
- GRE scores – a transcript of your Graduate Records Exam results.
- Research statement – a condensed version of a research proposal outlining your general research interests, if required.
- Recommendation letters – references from several academic referees who endorse your qualities as a person, your abilities as a student and your potential as a doctoral researcher.
Application Deadlines and Fees
Since PhD programs in the United States have taught components, they commence at the same time as all other taught degrees, and therefore share the same application deadlines and start dates. This corresponds to an application period that typically begins in August and ends in February. Admission decisions are typically made in April, with successful students starting in August/September.
When you apply to a graduate school, you will be expected to pay a fee for each doctorate application to cover the school’s administrative costs for processing your application. The fee varies from university to university, but typically ranges from $50 to $100.
Funding your PhD in USA
It’s very common for a PhD student to receive financial aid in the form of a PhD scholarship; in fact, this will be the case for the vast majority of students in the US.
PhD funding can be ‘fully funded’ covering the student’s graduate program tuition fees, accommodation and living costs, or ‘partially funded’ covering the student’s tuition fee only in part or full.
Besides funding, a graduate student can take on an assistantship, such as a graduate teaching assistant or research assistant, in which they take on a part-time salaried position at the university alongside their studies.
Due to the international and collaborate nature of American universities, there are also a number of international scholarships available, such as the Fulbright Scholarship and the AAUW International Fellowship.
PhD Duration in USA
In the US, a PhD takes approximately 5 – 6 years to complete if studying full-time, and 8 – 10 years if studying part-time.
If you already have a Master’s degree, your first phase can be shortened by one year at the discretion of the university.
Cost of a PhD in USA
The cost of a PhD program in the US can vary considerably depending on the type of university, i.e. whether it’s a public or private university, the doctoral course, i.e. whether it’s in a STEM subject such as computer science, engineering or a non-STEM subject, and whether you are a home or international student.
In general, however, the typical annual tuition fee for a PhD in the US is between $12,000 and $45,000 per academic year.
As with any doctoral degree, additional costs may include travel for collaborations, bench fees, accommodation and living expenses.
