Accelerated Program

Highly qualified undergraduates at Mississippi State University are encouraged to consider applying to the Accelerated Program.  This program permits enrollment in graduate courses in Agronomy, Horticulture, or Weed Science during the student’s final year of undergraduate studies.  Enrollment of up to 9 hours of graduate courses is approved for students admitted to the Accelerated Program.  Upon completion of the graduate course(s), undergraduate credit is also awarded for the course.  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 Plant and Soil Sciences with a concentration in Agronomy, Horticulture, or Weed Science.

Requirements for entrance into the Accelerated Program in Agronomy, Horticulture, or Weed Science for undergraduates include the following.

  1. A GPA of 3.50 or higher for all undergraduate work
  2. Submission of a standard application for graduate studies in the Department of Plant and Soil Sciences
  3. Three letters of recommendation from individuals familiar with the applicant’s academic performance
  4. Submission of scores from the Graduate Record Examination (GRE) General Test prior to enrolling in graduate courses
  5. A statement of professional interests and goals from the applicant, including specification of one or more potential major professors

For students enrolled in Accelerated 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.
