Highly qualified undergraduates at Mississippi State University are encouraged to consider applying to the Accelerated Program (Combined B.S./M.S.). This program permits concurrent enrollment in the Agronomy or Horticulture B.S. and the Agronomy, Horticulture, or Weed Science M.S. degree programs during the student’s final year of undergraduate studies with enrollment in up to nine hours of graduate courses for which undergraduate credit is also awarded. Students need to consult with a potential graduate advisor to ensure graduate credit could be applied to a program of study for the M.S. degree. Application to this program may be made as early as the end of the junior year (i.e., after completion of 90 or more hours of graded undergraduate courses). This option is only available for students pursuing a thesis-based Master of Science degree in Agriculture with a concentration in Agronomy, Horticulture, or Weed Science.
Departmental Admission Criteria
M.S. in Plant and Soil Sciences and Ph.D. in Plant and Soil Sciences with concentrations in Agronomy, Horticulture, or Weed Science:
- GPA—
For Master of Science: 2.75
For Doctor of Philosophy: 3.00 on graduate work - TOEFL (Test of English as a Foreign Language) or IELTS (International English Language Testing Systems) score—
TOEFL score of 500 PBT or 61 iBT or IELTS score of 5.5 - GRE—All graduate programs require submission of GRE scores.
- Non-thesis M.S.-- A non-thesis M.S. does not qualify toward admission to a Ph.D. program in the Department of Plant and Soil Sciences at Mississippi State University.
Accelerated B.S./M.S. program in Agronomy, Horticulture, or Weed Science for undergraduates:
- a GPA of 3.50 or higher for all undergraduate work;
- submission of a standard application for graduate studies in the Department of Plant and Soil Sciences;
- three letters of recommendation from individuals familiar with the applicant’s academic performance;
- submission of scores from the Graduate Record Examination (GRE) General Test prior to enrolling in graduate courses, and
- a statement of professional interests and goals from the applicant, including specification of one or more potential major professors.
For students enrolled in a combined B.S./M.S. program, the MSU Graduate Council has established these guidelines in cooperation with the Registrar’s Office:
Once the student is accepted into the combined program, the student and the advisor may select up to 9 hours that will satisfy both undergraduate and graduate requirements. These courses may be split-level (i.e., 4000-6000 level) or 8000 level classes, and the student should take the courses for graduate credit (i.e., 6000-level or higher). To do so, he/she must submit a completed form to the Office of the Graduate School requesting such permission: http://www.grad.msstate.edu/forms/pdf/accel.pdf . The OGS will notify the student by MSU email when the request is approved. The combination of undergraduate and graduate credit hours may not exceed 16 hours within a semester. After successfully completing the graduate-level classes, the student and undergraduate advisor will submit a request to the Registrar’s Office to grant credit for the course also at the undergraduate level with the same grade awarded as received for the graduate course. In the case of a split-level class, the transcript will show credit for both the 4000- and 6000-level on the transcript. In the case of an 8000-level class, a special topics undergraduate course of the same title will be entered on the transcript to allow dual credit.
Students are permitted to opt out of the combined program at any time, at which point they could complete only the undergraduate portion of the program. No additional dual counting of courses would occur after the student leaves the combined program.
Students will receive the bachelor’s degree once the requirements for that degree are met. Students will be required to complete all of the requirements for both the bachelor’s and master’s degrees in order to receive both degrees, and those requirements will be identical to the requirements for students enrolled in the traditional B.S. and M.S. programs. Students will be classified as undergraduates until they fulfill at the requirements for the undergraduate degree. At that time they will be classified as graduate students and will be subject to the guidelines pertaining to the M.S. degree. Students admitted to this program should read and understand the guidelines in the Department of Plant and Soil Sciences Graduate Student Handbook before registering for any courses for graduate credit.
Provisional Admission
A student who has not fully met the GPA or other requirements stipulated by the University may be admitted on a provisional basis. The provisionally-admitted student is eligible for a change to regular status after receiving a 3.00 GPA on the first 9 hours of graduate courses at Mississippi State University (with no grade lower than a C). The first 9 hours of graduate courses must be within the student's program of study. Courses with an S grade, transfer credits, or credits earned while in Unclassified status cannot be used to satisfy this requirement. If a 3.00 is not attained, the provisional student shall be dismissed from the graduate program.
Leveling Courses
The Department of Plant and Soil Sciences recognizes that many students who hold bachelor degrees from other educational areas may wish to study towards an advanced degree within the department. These students may come from areas with different requirements than those normally associated with Agronomy, Horticulture, or Weed Science. To increase the possibility of success in attaining the advanced degree, the department requires all graduate students to have a fundamental understanding of soil and plant science. To this end, all graduate students must have had at least one course in soil science equivalent to Soils (PSS 3303), a plant science course covering basic plant physiology, college mathematics, college chemistry, and college-level biology. Graduate students who do not possess these courses upon acceptance will be required to complete these courses during the first or second semester of their attendance at Mississippi State University.
General Department Completion Requirements
M.S. -- A thesis and an oral thesis defense are required. The graduate committee must approve the thesis topic, research proposal, program of study, and final thesis.
M.S. Non-Thesis -- A research paper approved by the student's graduate committee and an oral comprehensive exam are required.
Ph.D. -- The dissertation is required of all candidates for the doctorate degree. Original research, a written examination, an oral preliminary examination, and an oral dissertation defense and examination are required. At least one semester of teaching experience is strongly encouraged. The graduate committee must approve the dissertation topic, research proposal, program of study, and final dissertation.
Academic Performance
Students in the M.S. and Ph.D. degree programs must maintain a 3.00 GPA after admission to the program. No grade below C will be accepted for graduate credit. More than two grades ( 8 total hours) of C or below constitute grounds for dismissal. Note: C grades for a course that is retaken and in which the student earns a grade of B or higher will not be included in the 8 total hours. However, the original grade is included as part of the calculation of the GPA. At any time, the student will lose any departmental assistantship should his/her cumulative GPA drop below a 3.00. Students with alternative sources of funding (scholarships, fellowships, etc.) must follow the rules and regulations of the funding source.
