Environmental Sciences, Agriculture Concentration, Ph.D.
Agriculture has many connections with Environmental Sciences, including study areas of sustainable and organic farming, applications of technology and engineering, and effects of pesticides and fertilizers on plants, animals, and ecosystems, to name a few. Tennessee Tech has the Shipley Farm and other operations that provide a venue for dissertation research projects in Environmental Agriculture and the faculty in the School of Agriculture offer coursework and advise graduate students in this area.
Applicants who do not fully meet the following requirements may be admitted in Provisional Standing on the basis of a favorable recommendation to the Associate Dean of Graduate Studies by the appropriate departmental chairperson and the Director of the Environmental Sciences doctoral program. If admitted in Provisional Standing, the student must remove all deficiencies and apply for reclassification to Full Standing prior to the completion of 15 hours of graduate work.
Application materials may be obtained from the Graduate School Office.
Applicants for admission to the doctoral program in Environmental Sciences must have:
- a bachelor’s or master’s degree in science, mathematics, engineering, or environmental science;
- a grade point average of 3.0 or above on a 4.0 scale;
- international students must have a score of 525 or above on the TOEFL;
- and GRE score of at least 300 (Quantitative + Verbal) and 3.5 (Analytical Writing) for students entering any concentration within the Environmental Sciences Ph.D. degree program.

Guidelines for Committee and Comprehensive Exam
Guidelines for Graduate Committee Composition
The organization and appointment of advisory committees to supervise graduate study for the degree of Doctor of Philosophy in Environmental Sciences shall be the same, generally, as in the master’s program, except that the advisory committee shall consist of at least five (5) members of the Graduate Faculty, plus the Director of Environmental Sciences Ph.D. program who serves as an ex officio, nonvoting member. Three (3) members shall be from the student’s area of concentration, either Biology or Chemistry. Two (2) members shall be from separate departments of the environmental science core outside the student’s area of concentration. Changes in a Ph.D. advisory committee must adhere to all policies and procedures governing graduate study at the University, as contained in the Graduate Catalog and administered by the Director of Graduate Studies.
Guidelines for the Comprehensive Examination
Prerequisites. Before requesting that his or her major professor schedule a Comprehensive Examination, a student must:
- have achieved Full Standing in the program
- completed approximately 80% of the course work in his/her Program of Study
The test will consist of written and/or oral portions. The student’s advisory portion will consist of four (4) sections. Total time for each section should not exceed eight (8) hours. Three (3) sections will contain material from the student’s area of concentration and one (1) section will integrate material from the Environmental Sciences Core Curriculum.
If an oral exam is to be included as part of the comprehensive exam it will be administered by the student’s advisory committee within three (3) weeks of the successful completion of the written portion of the exam. A question will be included in the oral exam that tests the student’s understanding of the interdisciplinary nature of Environmental Sciences.
If an oral exam is included as part of the comprehensive exam, both portions of the Comprehensive Examination will be completed during one (1) academic semester.
Four-fifths of the voting members of the committee must agree that the student has successfully completed the comprehensive exam.
The student will be given one (1) additional opportunity to pass each portion of the Comprehensive Examination. Failure to pass either portion on the second try will result in the student’s dismissal from the Ph.D. program.
A written evaluation of the student’s performance on the Comprehensive Examination will be prepared by the student’s advisory committee and kept on file in the office of the Director of the Environmental Sciences Ph.D. program.
Successful completion of the Comprehensive Examination must be achieved in a timely fashion. The complete Comprehensive Examination must be scheduled and taken within a year following the completion of 80% of the course work in the student’s Program of Study, including successful completion of all core courses. It shall be the student’s responsibility, in consultation with his/her advisor, to schedule this examination at a date agreeable to the whole examining committee. The committee shall be given at least two (2) months advance notice of the Examination date in order to make preparations. Any second attempts to pass portions of the Comprehensive Examination must be scheduled in the subsequent (Fall/Spring) semester. Failure to follow these procedures shall result in the student’s dismissal from the program. Any appeal by the student for exceptions to this policy shall be made in writing and submitted to the Executive Committee of the Ph.D. program.
