Steps for writing an SOP for Ph.D.

Although the format of writing a statement of Purpose (SOP) for the Ph.D. program is almost similar to the SOPs required for other courses, certain differences need to be taken care of when drafting an SOP for a Ph.D. 

  • Create a statement of purpose for yourself: Simply inform the admission committee about yourself. The foremost objective of an SOP is to describe yourself as a person. The essay should provide information regarding the intellectual trajectory and why it is necessary for you as a student to broaden your horizons in the field of education by completing a Ph.D.  Also, it is important to avoid the faculty and university about your greatness multiple times. Rather the SOP should showcase the importance of studying under such faculty is important for the student and how it will impact the overall life in the future.
  • Answer all the why questions: It is important to answer all the possible reasons for selecting a Ph.D. in the SOP for Ph.D. The SOP should provide information regarding the different reasons that resulted in creating interest in completing the degree and why it resulted in selecting the particular field for specialization, along with the reasons for selecting the particular university.
  • It is important to be straightforward regarding your research interest: It is advisable to mention in the introduction the relation between your interest or passion with the particular field of the subject selected for your Ph.D. This is the place where the candidate proposes the research topic to the institution or university. In case the candidate is not sure about the research topic, then the students can provide information regarding the field of study and different possible options it can provide for the candidate. In case the candidate is willing to select two or more subjects, in that case, they should provide information regarding them also. When writing the SOP it is important to make sure that it answers the following questions:
  • “What is your research topic or field, and why”?
  • “What have you learned in this field so far that made you take up this topic”?
  • “How passionate are you about pursuing this further”?
  • Research and academic background: Provide short information regarding the academic background beginning with the bachelor's degree. After the bachelor’s degree provide information regarding the master's degree and how it is related to the selected research topic. In this section, the students can provide information regarding the different research projects completed by the candidate. The candidates should mention the title of the dissertation and explain the objectives of the research along with procedures used to conduct the research in a glimpse. For example, the information can include how you took the assistance of the faculty members, referring to other research, and conducting a survey.  Also, the students need to note that the entire research should not be copied here. Information related to procedures and learning objectives should be mentioned. Also if the research paper has been published or is in the process of approval, the fact should be highlighted. The students should focus on skills, knowledge, and expertise gained during the completion of the research study and how they will be helpful in future research during the completion of the PhD. The students should also mention any practical expertise gained during the completion of the research.
  • It is important to address the previous issues directly: In case the candidates receive negative marks in previous academic qualifications, it is important to provide information about these issues directly in the SOP for PhD.  It is important to provide information regarding their negative marks and what they learned from them. Taking the negative marks to the admission committee showcases the ability of the candidate to handle problems and emerge as a strong person. 
  • Reasons for joining the specific university and course: It is one of the most important sections of the SOP and helps in answering the main question of the admission committee which is why you have selected the particular university and the course.  The question is very important as this question can make or break the entire profile of the candidate. The answer to this question should begin by selecting a particular professor and their research. Provide references of faculty, departments, amenities, professors, labs, and research centers in the university. Also, it is important to mention the role of the selected university and course in fulfilling the short-term and long-term goals of the candidate. When answering the Why question it is important to cover the following risk
  • “Why this program”?
  • “Why this university/ department”?
  • “Why this specialization”?
  • “Why study/ research under the tutelage of a certain professor”?
  • Career goals: Career goals are also an important part of the application process for PhD admission. Whether the SOP is written for UG students, MBA aspirants, or Ph.D. candidates, the lack of clear goals in the minds of the students, results in making the readers lose their interest in the profile of the candidate.  This also results in highlighting that the candidate is not serious regarding their course and just applying for admission for fun. Therefore, it is important to make sure that the career goals of the candidate should align with the course selected by the candidate and also with the research conducted previously.  Also, the students can provide information regarding the future, research works that they are willing to undertake, and how much impact they will make in the particular society. The goals of the candidate should be divided into two distinct paragraphs. The first paragraph should provide information regarding the short-term goals of the candidate, such as what the student wants to do just after completing the course. It may include processes such as conducting future research, making practical use of the research, pursuing research in any other field, or joining the research and development division of any other industry or firm or else. The second paragraph should include the long-term goals of the candidates, such as where the candidate wants to see themselves in the next 10-15 years. These will be the ultimate goals of the candidate for their life such as holding the post of the general manager in a reputed firm, starting their own business, or starting won R&D department of their own, or something like that. However, it is important to note that the long-term and short-term goals of the candidate should be linked with the course selected by the candidate for graduation.
