Degree Plan

NOTE: It is highly recommended that all graduate students in the Department of Horticultural Sciences have taken or will take 6 credit hours of 200, 300, 400, or 600 level HORT courses prior to admission. In the event that a student is deficient in HORT courses, the student’s committee can require the student to take an additional 6 credit hours of HORT (300, 400 or 600 level courses) as part of their degree  The courses must be approved by the Chair of the student’s Advisory Committee.  Any 300, 400, or 600 level courses may be applied towards the student’s Degree Plan with the Chair and Committee’s approval.  These 6 hours of HORT courses will be in addition to the 9 hour Master’s and 12 hour Doctoral requirement at the 600 level for all HORT graduate students.  If the student is deficient in the non-HORT supporting field courses (for example: chemistry, soils, plant physiology, etc.), the Chair will determine course prerequisites that need to be taken.

More information about the Department of Horticultural Science’s graduate faculty and their research can be found in Table 2 of the TAMU Graduate Horticultural Sciences Policy Handbook.
