What is a PhD? Top Colleges of PhD in India, PhD Entrance Exams, History of PhD



A PhD stands for Doctor of Philosophy, an academic or professional degree that generally allows individuals to teach their chosen subject at the university level or pursue specialized positions in their field.


A PhD, or Doctor of Philosophy, is the highest academic or professional degree, enabling individuals to teach at universities and excel in specialized roles within their fields. While "philosophy" originally signified broad knowledge, modern PhDs reflect deep expertise and dedication to specific subjects. Pursuing a PhD is ideal for those with a passion for wisdom and a particular academic interest.


A Doctor of Philosophy (PhD) primarily involves intensive research in a chosen field, distinct from traditional learning. Doctoral candidates identify gaps in existing knowledge, conduct original research, and compile it into a substantial thesis or dissertation. This process can take several years.


PhD candidates work closely with advisors, follow rigorous scientific methodologies, and aim to advance their field's understanding by contributing novel theories, insights, or practical applications. They may also assist in teaching and publish their research.


A PhD offers diverse career opportunities, extending beyond academia to research, government, industry, consulting, and more. PhD programs can be highly specialized or interdisciplinary, allowing the combination of knowledge from various fields.


Upon completing their thesis, candidates must defend their findings and methodology before an academic panel. This oral examination, called the viva voce (in the UK) or dissertation defense (in the US), is the final step toward earning the degree.


If you possess a passion for wisdom and a strong academic interest, a PhD may be the ideal path for you.


History of PhD

In the history of PhD, the term 'philosophy' originates from the Ancient Greek word ‘philosophia’, which directly translates to 'love of wisdom.' Initially, it referred to individuals with a well-rounded education in fundamental worldly matters. Today, a Doctor of Philosophy still necessitates a love for wisdom but pertains to those who have dedicated themselves to specialized knowledge in their chosen field.


Traditionally, a PhD program involves three to four years of full-time study, during which the student conducts substantial original research and presents it in a thesis or dissertation. Some PhD programs accept a portfolio of published papers, and in some countries, coursework may also be required.


An essential part of the PhD process is the 'viva voce' or oral defense, where the student defends their research findings. This can be a relatively short session with a few examiners or a more extended examination panel, typically lasting one to three hours. While traditional PhD programs often require on-campus study with close supervision, many universities now accept part-time and distance-learning PhD students due to advancements in distance education and e-learning.

PhD Admission Requirement

PhD admission requirements typically consider the candidate's academic achievements, both at the bachelor's and master's levels, as well as their potential for research. Most universities require candidates to have an honors degree or a master's degree with excellent academic performance. In some cases, a strong master's degree alone may be sufficient for PhD admission. The specific grade requirements may also depend on the type of funding you intend to use; self-funded applicants may have more flexibility.


For certain institutions and subjects, like psychology, humanities, and some sciences, it might be necessary to secure a committed tenured professor from the institution as your formal advisor and supervisor before gaining formal acceptance into the PhD program. In other cases, you may be assigned a supervisor based on your research interests after being admitted to the program.


To improve your chances of successful admission, it's advisable to reach out to a faculty member at your chosen institution beforehand. This allows them to assess the alignment of your research interests with the department and can even help you brainstorm potential PhD research topics.


PhD Applications

PhD applications involve various components to assess a candidate's qualifications and suitability for doctoral studies. Here are the key elements often required:


Language Proficiency

Some PhD programs necessitate proof of proficiency in the language of instruction. This can be demonstrated through standardized language exams or academic coursework in the relevant language.


Employment/Academic Records

Applicants might need to submit a résumé detailing their work experience, along with academic transcripts that provide information about courses and module content. Additionally, details of prior research projects and publications can strengthen the application.


Academic References

Most applicants are asked to furnish academic references from individuals who are well-acquainted with their academic performance. These references should emphasize the candidate's coursework, research capabilities, research potential, and dedication to their chosen field of study.


Personal Statement

Many institutions require a personal statement, which is a brief essay allowing candidates to express their passion for their chosen subject. It's an opportunity to explain motivations for pursuing a PhD, relevant extracurricular activities, and research interests. Some universities provide guidelines on writing personal statements to help tailor them to the institution's expectations.


PhD Research Proposal

Applicants are typically expected to submit a research proposal outlining their intended research. This proposal should include:

  • A context within existing research.

  • Awareness of ongoing debates in the field.

  • Demonstrated analytical skills.

  • Identification of knowledge gaps.

  • A research hypothesis addressing these gaps.

  • Detailed research methodology.

  • Consideration of real-world policy implications.

The research proposal aids admissions committees in evaluating a candidate's research aptitude, alignment with faculty research interests, and the institution's available resources.


It's crucial to research institutions thoroughly before applying to ensure your research interests match their focus. While the initial research proposal isn't usually binding, it provides a foundation for further development. In some fields like science and engineering, predefined research projects may be offered by the institution, with candidates demonstrating their suitability. However, in arts, humanities, and social sciences, candidates often submit their research proposals.


Qualification Requirement for PhD

If you're interested in pursuing a PhD but lack the requisite qualifications, there are potential avenues to apply for a PhD program. Your chosen institution may have specific requirements that allow you to apply under certain conditions. These conditions could include:


  • Additional Study: You might need to complete further coursework or academic prerequisites to bridge the qualification gap.


  • Qualifying Examination: Some institutions may require you to pass a qualifying examination to demonstrate your readiness for doctoral studies.


  • Special Case Consideration: In certain cases, you could make a special appeal to your chosen institution. This could be based on factors like possessing non-degree professional qualifications and substantial practical experience.


To pursue a special case application, it's essential to secure strong support and guidance from a potential supervisor who can advocate for your admission. Seek their advice before proceeding with this type of application.

PhD Through M.Phil

Another avenue for aspiring PhD candidates is to initiate their journey as a general research student or pursue an MPhil degree. This is a popular route for many PhD candidates, especially those lacking a strong research background. The MPhil represents an advanced master's degree focused on research and can be an ideal choice for students seeking to bolster their research skills. It typically involves some structured coursework, particularly in research methods.


Upon successful completion of a one-year structured program, students may earn an MRes degree. This degree includes a more substantial coursework component compared to the MPhil and can be awarded as a substitute for a PhD, especially for students who haven't fulfilled the requisite duration for a full PhD program.


Alternatively, the accomplishment of original research may lead to the conferment of the MPhil degree without necessitating a formal dissertation defense, a prerequisite for earning a PhD.


In some cases, typically after the first or second year of research (often during the MPhil phase), if the academic institution is satisfied with the progress and quality of your work, you may have the opportunity to apply for full PhD registration. Typically, your academic supervisor or tutor plays a pivotal role in assessing your readiness to advance to a PhD program. If you are deemed prepared, you will then need to formulate a thesis title and select your PhD program. This flexible pathway allows students to gradually transition into a full PhD program based on their research achievements.


Starting Carrer in PhD

Once your registration is complete, you can expect to receive official notifications that include the following information:


  • Supervisor Assignment: You will be informed about your supervisor(s) and their areas of expertise, guiding your research journey.

  • Research Topic or Field: The specific topic or field of research for your PhD program will be provided.

  • Thesis Submission Timeframe: You will learn about the minimum duration required before you can submit your thesis.

  • Assessment Methods: The formal assessment methods preferred by the institution will be outlined.


Most academic institutions will also furnish you with a comprehensive list of provisions and available facilities for PhD and research students. Additionally, they will provide a detailed roadmap of the key milestones you must achieve during your PhD journey. Your academic supervisor will play a crucial role in guiding you through these milestones, tracking your progress, and offering advice on your next steps. Satisfactory progress must be made each year to continue your PhD studies.


Alternatives of PhD Degree

As you explore PhD programs, remember that there are various types of doctoral degrees bearing the title "doctor," including the Juris Doctor (JD), the Doctor of Physical Therapy (DPT), the Doctor of Pharmacy (DPharm), and the Doctor of Medicine (MD) in the U.S. and Canada.


These degrees are not typically classified as PhDs because they may lack a fundamental component that characterizes the PhD: academic research. Instead, these are often referred to as entry-level doctorate degrees. Individuals who desire to pursue a PhD can do so later, often referred to as a "post-professional doctorate."


For example, JD and MD programs in the U.S. and Canada may not universally require students to complete a specified academic research component for degree completion. However, many research-oriented degrees, including the MD, involve scholarly research, often published in peer-reviewed journals, making them akin to PhD programs. As a result, some countries consider them equivalent. Some institutions offer combined programs that integrate professional training and research, such as the MD-PhD dual program, catering to medical professionals seeking research careers.


Higher Degree Than PhD

Beyond the Doctor of Philosophy (PhD) and equivalent degrees, there exists a category of "higher doctorates," which are considered a step above a standard PhD These are most prevalent in UK universities and some European countries, though they are increasingly awarded as honorary degrees. In contrast, the United States primarily confers such titles as honorary degrees, often denoted by appending 'hc' (for honoris causa) to the end of the degree title.


Here are some examples of higher doctorate degrees:


  1. Doctor of Science (DS/SD): Awarded in recognition of a substantial and sustained contribution to scientific knowledge that surpasses the requirements for a PhD

  2. Doctor of Literature/Letters (DLit/DLitt/LitD): Granted to acknowledge achievements in the humanities or original contributions to the creative arts.

  3. Doctor of Divinity (DD): Typically conferred above the Doctor of Theology (DTh) and recognizes significant accomplishments in ministry-oriented fields.

  4. Doctor of Music (DMus): Bestowed in the UK, Ireland, and some Commonwealth countries based on a substantial portfolio of compositions and scholarly publications related to music.

  5. Doctor of Civil Law (DCL): One of the highest doctorate degrees, following the DD, awarded for exceptionally insightful and distinctive publications containing significant and original contributions to the study of law or politics.


These higher doctorates are typically reserved for scholars who have made remarkable and lasting contributions in their respective fields, marking a pinnacle in academic recognition.
