Admission – Applied Systematics in Botany Program


Contact Dr. Aaron Liston, Program Director, for more information on the program.

Professional Science Master’s (PSM) Programs at Oregon State University normally accept applicants for Fall Term enrollment only. Up to ten positions are open annually in this program, and students or working professionals who have a background in math, science, or engineering are encouraged to apply.

The Applied Systematics in Botany Program Graduate Admission Review Committee evaluates applications based on the following criteria:

  • GPA: All applicants must have at least a 3.0 GPA (4 point scale) for the last 90 credits of coursework.
  • Transcripts and curricular preparation: A 4-year undergraduate degree in math, science, or engineering is required.
  • GRE scores: The Graduate Record Exam is required, and a minimum score of 1,100 combined verbal and analytical (or 300 based on new scoring system) is recommended. Scores should be sent directly to the Graduate School.
  • TOEFL scores: Scores for the Test of English as a Foreign Language must be included with your application if you are an international student. The Graduate School at OSU requires a minimum TOEFL score of 550 (paper-based test), or 80 total score with all subscores 18 or above (Internet-based Test [iBT]) for regular admission. The TOEFL is not required for international students holding a bachelor or master’s degree from an accredited U.S. university or college.
  • Major professor: While you are not required to secure a major professor prior to being admitted into the program, you are strongly encouraged to do so.
  • Statement of interest: Type “Professional Science Master’s” at the top of your statement of interest. This 1-2 page narrative should succinctly summarize your education, employment history, your long-term career goals, and how this degree program will help you achieve these goals.
  • Letters of recommendation: Arrange to have three letters of professional reference sent directly to the Department of Botany and Plant Pathology.

Both the Graduate School and the Department of Botany and Plant Pathology need to approve your application. Go to http://oregonstate.edu/admissions/graduate-students to apply online (preferred) or download and mail your application along with your transcripts, TOEFL scores, GRE scores and $60 application fee to the Graduate School. Have your statement of interest and letters of recommendation sent in one packet, if possible, directly to the Department of Botany and Plant Pathology, 2082 Cordley Hall, Oregon State University, Corvallis, OR 97331.

When completing application forms, you will need major codes:

  • The OSU institution code is 4586.
  • The Applied Systematics in Botany PSM Program code for applicants is 5160.

Additional information regarding admissions for international applicants is available online at http://oregonstate.edu/dept/grad_school/future/international.php and http://oregonstate.edu/admissions/international.
