The graduate school Statement of Purpose is a document that complements your resume and application form, describing your profile in a narrative way and convincing the admission committee that you would be a good match for a particular department or program. Take into account that matching goes both ways: they should be interested in you, and you should be interested in them. Your Statement of Purpose should make this match clear.
Your Statement of Purpose will be read by a graduate committee – a handful of faculty from the program. They’re trying to determine if you will be a successful graduate student in their department and a successful scientist after you graduate. They are interested in your qualifications as a researcher, your career goals, and how your personality matches their labs and department.
The graduate committee probably reads hundreds of applications every year. To make it easy for them to figure out that you are a good fit, consider the following suggestions:
PhD programs invest in the professional and scientific growth of their students. Get the committee excited about investing in you by opening your essay with a brief portrait of what drives you as a scientist. What research directions are you passionate about, and why? What do you picture yourself doing in 10 years?
Close your essay with a 2-3 sentence discussion of your long-term career interests. No one will hold you to this; this just helps your committee visualize your potential trajectory.
Experiences are the “what” of your essay. They are the most efficient and easiest way to prove your capabilities to the admissions committee.
Achievements are not limited to research projects or publications. You can discuss, for example, a research-oriented class project in which you stood out, and that is related to the type of work you expect in graduate school. Think about experiences demonstrate your ability to conduct research.
Quantify your experiences to show concrete impact. How many people were on your team? How many protocols did you develop? How many people were in competition for an award? As a TA, how often did you meet with your students? Describe actions. Rather than share how important the company was or how renowned the professor you worked with is, always direct the message to highlight your performance, which may include both independent and collaborative work.

A key point on writing your Statement of Purpose is to demonstrate that you have done previous research about the program to which you’re applying, that you understand its characteristics and objectives, and that you are really interested in joining it and willing to do your best to be successful in it. To do this:
State which professors in the program you would be interested in working with. Show how their research areas align with your background and your goals. You can even describe potential research directions or projects.
Many schools distinguish between the Statement of Purpose/Objective and the Personal Statement, providing different writing prompts for each. The main difference between these two types of essays is that the Statement of Purpose focuses on your professional background, goals and research interests, while the Personal Statement is more about your personal history and where your motivation for graduate school comes from.
