What Is a PhD Degree?

After earning a bachelors degree and a masters degree, you may be considering taking your education even further.

The next step for you might be a Doctor of Philosophy degree, better known as a PhD. As a terminal degree, a PhD can set you apart as an expert in your field. Earning a doctoral degree is not a small undertaking. The process includes multiple steps and can last for several years.

Components of a Ph.D. degree program often include:

  • Advanced courses in your chosen field
  • Classes in research methods, data analysis, and scholarly writing
  • Examination of current literature and studies related to your field
  • Oral or written comprehensive exams
  • Original research project—includes writing and defending a major paper about your research

The dissertation, sometimes known as a thesis, is usually the part of a PhD program that takes the longest. During the dissertation process, you’ll work under the supervision of a faculty advisor, often someone whose research interests correlate with yours. You’ll design a research project, carry it out, and write about your findings. This project is meant to contribute new ideas to your field.

A PhD is particularly suitable for students who love school settings and want to pursue academic careers. For instance, professors often have PhDs. It’s also common for scientists and other researchers to hold this type of degree. Outside of  academia, a PhD could set you apart as a knowledgeable leader in your field.

Benefits of a PhD Degree

Getting your PhD can be an incredible personal goal worth achieving. Plus, a degree at this level can offer many professional benefits, such as:

  • Career advancement. As a person with a PhD, you may be considered an expert in your field. That could help qualify you for a variety of top roles within your line of work.
  • Higher earnings. A job promotion or a new employer might offer you a higher salary.
  • Networking. You can meet new people and build professional connections as you work toward a PhD.
  • Preparation for becoming a professor. Universities typically prefer to hire faculty members who hold PhDs in their area of expertise.
  • Research opportunities. Before you can earn your PhD, it’s necessary to complete an original research project called a dissertation. After completing your degree, you may have additional opportunities to contribute research to your field.

If you’re willing to put in the work, then getting your PhD could be worth the effort.

How to Know If a PhD Is Right for Me

Before you sign up for a PhD program, it’s helpful to carefully weigh the decision and make sure it’s the right choice for you. You might ask yourself the following questions:

  • Am I willing to commit years to the process? PhDs take at least 3 years, and most take longer than that.
  • Do I want to carry out original research? This is a research-focused degree, and the purpose is to contribute new ideas or theories to your field.
  • Does an academic career interest me? Many people get PhDs because they want to work in higher education as teachers or researchers. Those who plan to remain as practitioners often consider professional doctorates instead.

It can also be helpful to speak with faculty members and current students to get a feel for what you can expect from PhD studies.

Applying for a Ph.D: Education Requirements

It’s necessary to put in years of study before you can apply for a PhD program. Most students need to hold at least two degrees already. But, in some cases, one may be sufficient.

  • Bachelor’s degree. All graduate programs require students to have earned a four-year undergraduate degree before enrolling in advanced studies. Most PhD programs don’t specify that your bachelors degree must be in the same field as your hoped-for doctoral studies, but it can help you move through a graduate-level program with more ease.
  • Master’s degree. Colleges often expect students to have earned a master’s degree before applying for PhD studies, but some programs do allow students straight out of bachelor’s degree programs. Doing a master’s degree first can provide strong preparation for the advanced coursework, research, and writing that are required in doctoral programs.

It is often required that the degrees you have be from accredited colleges. It may also be necessary to meet a minimum GPA requirement, such as a score of 3.0 or higher. Some colleges prefer PhD applicants who have graduated from previous programs with honors.

Doctor of Philosophy: Admissions Requirements

Doctoral programs can be quite selective about whom they admit because they’re looking for capable students who can keep up with the demands of the program and contribute valuable new research to the field.

In addition to meeting the education requirements, you’ll also be required to turn in records that demonstrate your academic potential. Here are some common admissions requirements:

  • College transcripts and professional resume
  • Letters of recommendation from people who know you academically or professionally
  • Statement about relevant background, research interests, or professional goals
  • Proposal that presents the original research project you’d be interested in doing
  • Scores from the GRE or GMAT (not always required)

You might also connect with the department’s faculty members and find someone who would be willing to serve as your academic supervisor for your dissertation. It’s beneficial for this person’s research interests to align with your own.

Some schools have you do this before admission, and others connect admitted students to supervisors later in the enrollment process.

What Does PhD Stand For?

PhD stands for “Doctor of Philosophy.” It doesn’t mean that you’ve studied philosophy at the highest levels. Rather, the word “philosophy” in the name refers back to ancient Greek. It implies that you are someone who loves and seeks wisdom and knowledge.

You can get a PhD in many different subject areas—such as a Doctor of Philosophy in Mathematics or a Doctor of Philosophy in Psychology. PhD students explore their chosen field of study in great depth. They also learn how to conduct original research, and they undertake major research projects. By graduation, they are considered experts in their fields.

What Do You Learn in a Doctoral Degree?

In a PhD program, you’ll learn about your chosen area of study, such as biology or sociology. You will also study a niche area within that field in great depth.

Research is a significant topic in any PhD program. Your courses might include topics on:

  • Advanced statistics
  • Dissertation preparation
  • Literature review
  • Quantitative and qualitative methods
  • Research methodology

These research-focused classes may be tailored to your particular area of study, such as research methodology in the social sciences or advanced statistics in criminal justice research.

What Can You Do with a PhD Degree?

Many people earn PhD degrees because they want to teach at the college level. This degree is often required for tenured faculty positions at universities.

The Bureau of Labor Statistics states that most postsecondary teachers earn between $46,690 and $172,130 each year. Research scientists often hold PhDs as well. Examples include medical scientists, biochemists, and physicists.

Additionally, there are some career paths that require a doctorate for licensure. For instance, clinical and counseling psychologists usually need to receive training at the doctoral level before they can practice independently.

Do You Need a Masters to Get a PhD?

Whether you’ll need a masters before you can begin the PhD process will depend on the program you choose.

Many PhD programs require a master’s degree as an admissions requirement. Completing a master’s program can provide a strong research and writing foundation that can help you during this advanced program. Other programs, though, let students enroll with only a bachelors degree.

There might be additional classes required to prepare you for working at the graduate level, so it may take a bit longer to complete your studies. For more information on whether you need a master’s to get a PhD, you can consult the admissions requirements of each program you’re considering.

Can You Get a PhD Online?

There are many online PhD programs available for aspiring students looking for flexibility. Some PhD programs are offered entirely online. You can take all of your classes online, and you can also receive guidance from your faculty advisor and defend your dissertation from afar.

Other programs are mostly online but require some in-person experiences. You might be asked to come to campus for a week or two of intensive study. Also, you may be asked to show up in person for your dissertation defense. Either way, online PhD studies are often more accessible for working professionals than fully on-campus programs.

How Long Does It Take to Get a PhD?

Students often spend 3 to 5 years completing a PhD program. Online programs sometimes include features like year-round classes and short course terms that encourage quick completion.

The shortest PhD programs typically do not involve writing a dissertation. There may be a different final assignment, such as a capstone project, instead. You might be able to finish one of those programs in about 3 years. Not all students finish within 5 years. Some spend around a decade on this massive undertaking. Some PhD programs set an upper limit for completion, such as 7 or 8 years.

Is a PhD a Doctor?

People with PhD degrees

People with PhDs are considered experts in their fields, and the degree includes “Doctor” in its name. For that reason, PhD holders often use the title “Doctor.” A college professor, for example, might go by Dr. Smith.

Even still, there’s a difference between MD vs. PhD. A person who holds a PhD is not a medical doctor. Medical doctors earn a Doctor of Medicine (MD) degree before becoming licensed to practice medicine. In most contexts, though, people refer to professionals with PhDs as “doctors.”

What Jobs Can You Get with a PhD?

People with doctorate degrees work in both academia and professional practice. Being a college professor is quite popular among people who hold PhDs. The Bureau of Labor Statistics says that a PhD can also be helpful for obtaining jobs in higher education administration, particularly as a dean or a provost.

PhD graduates may work in research as well. Research jobs are available with colleges, government agencies, and private institutions. Researchers are needed in many different fields, including biology, mathematics, computer science, and economics. PhDs also help people rise to the top in their industries, perhaps as chief executives.

How Much Does a PhD Cost?

Some graduate schools charge just $300 to $400 per credit hour. Others may charge $2,000 per credit hour or more.

Per-credit-hour rates between $600 and $1,000 are quite common. It’s helpful to keep in mind that state universities often charge less for in-state residents than nonresidents. Your total number of credit hours may depend on how many years you spend working on your dissertation.

Some universities offer tuition-free PhD programs for qualifying participants. The students may even receive a stipend in exchange for research or teaching assistance. This arrangement is more common for on-campus programs than online ones.

What’s the Difference Between a Doctorate vs. PhD Degrees?

Is a PhD a doctorate degree? For your terminal degree, you may have the choice between a PhD degree and a professional doctorate. While they are both doctoral degrees, they do have some differences.

Doctorate Degree PhD Degree
  • Focused on working as a professional in the field
  • Involves putting research and theories into practice
  • May include a capstone project or a dissertation
  • Often leads to hands-on jobs in your chosen field
  • Focused on research and academia
  • Involves developing original research to move the field forward
  • Usually includes a dissertation
  • Often leads to jobs in higher education or research

Professional doctorates are sometimes a year or two quicker than PhDs, but that’s not always the case.

Is a PhD Worth It?

Yes, a PhD is worth it for many students. For one thing, holding a PhD could be the key to fulfilling your professional dreams.

If you want to be a professor, for instance, there’s a good chance that you’ll be required to have this advanced degree. Even if that’s not your ultimate goal, a PhD could be beneficial. The more education you have, the more your job security usually increases.

According to the Bureau of Labor Statistics, there’s an inverse relationship between education and unemployment. As education increases, unemployment rates decrease.
