Master of Science in Environmental Management

The Master of Science in Environmental Management degree at Hardin-Simmons University has been designed to give you the experience, analytical skills, and knowledge necessary to make you an effective environmental professional.

Students doing internships will gain valuable experience in such diverse settings as Dyess AFBTCEQ, West Texas Utilities Co., local manufacturing facilities, and local school districts.

Each Environmental Management graduate student takes a minimum of three hours of special topics courses designed to provide valuable professional training and, in many cases, professional certification. All of these experiences provide invaluable opportunities for hands-on application of the knowledge you will gain at HSU.

Why earn a Master of Science in Environmental Management at HSU?

While the program is designed for students with a natural sciences background, there are self-paced leveling courses in biology, chemistry, and geology for those with non-science backgrounds. Graduates with undergraduate degrees in diverse areas, ranging from criminal justice to engineering, have succeeded in the program.

Flexible Scheduling

The course schedule has been prepared with your career plan and busy schedule in mind. The program can be completed in two years, and all classes are offered in the evenings or on weekends.

Total Hours 34

Thesis Track

  • Core Curriculum 27

Total Hours 33 *The thesis track may require additional leveling work beyond that required as prerequisites for admission to the program.


Under close supervision, the student will complete original research of a topic to be determined jointly by the student and thesis advisor, with the approval of the program director. The thesis advisor will be a graduate faculty member chosen by the student and approved by the program director. Once the student begins work on the thesis, continuous enrollment in either Thesis or Thesis Renewal is required for all fall and spring semesters until completion of the thesis. Summer enrollment is required if the student anticipates working on the thesis or completing his/her degree during either summer term. *A
thesis process fee is assessed.

Comprehensive Exam

During the final nine hours (or final semester) of course work, the student should request in writing to his/her faculty advisor permission to take the comprehensive exam. The exam will be administered by a committee of three graduate environmental management faculty recommended by the program director and approved by the Dean of Graduate Studies.

Time Limit

All work required for a Master of Science degree in Environmental Management must be completed within a period of five years from semester of first admission.

Admission Criteria

Applicants for graduate study in Environmental Management must hold a bachelor’s degree from a regionally accredited college or university. Admission to the program requires the program director’s endorsement, which will be based on evaluation of the following elements:

  1. Prior academic performance, which will be evaluated in regard to (1) overall G.P.A., (2) G.P.A. in natural sciences, (3) overall upper level G.P.A., (4) previous graduate course work, and (5) fulfillment of necessary prerequisites (see below). An overall G.P.A. of 2.7 or a G.P.A. of 3.0 in either natural science courses, upper level courses, or graduate courses is considered the norm.
  2. If required, a Graduate Record Exam (GRE) score for the verbal and quantitative subsets or a full scale Graduate Management Admission Test (GMAT) score. Scores at the 50th percentile or higher are considered the norm.
  3. A writing sample [personal essay] concerning the applicant’s reason for applying and how the completion of the program will serve the applicants career goals.
  4. Occupational experience in either the environmental or health and safety field [include in the writing sample #3].
  5. An interview with the program director.

Early Admission Option (Combined BS/MS Degrees)

This option is for undergraduate students at HSU who are enrolled in the Environmental Science minor and desires to pursue the MS degree in Environmental Management (ENVM). With proper scheduling it is possible for a student to acquire both BS and MS degrees within five years.

Students in their senior year who meet the entrance requirements for the ENVM program may be admitted to the program and take ENVM courses for graduate credit. Six hours of ENVM coursework (to include ENVM 5311) will count towards the student’s baccalaureate degree and reduce the hours required for the MS degree by a like amount. Successful applicants may then attempt an additional 9 semester hours of graduate course work, completing the first year of the ENVM program.

Students who pursue this early admission option and are not subsequently admitted to the ENVM program or do not complete the program, will receive their baccalaureate degree, provided that all undergraduate degree requirements are met.


While interdisciplinary in nature, and accepting candidates with a variety of undergraduate degrees, this program is technical and scientific. Two semesters each of Biology, Chemistry, and Geology, or the equivalent, are ideal for admission.
Students lacking all or part of these requirements, however, may still enroll in the program. Two Environmental Science courses are required for the program (ENVM 5311 and 6311).

Note: The program director in consultation with the student will determine if other prerequisite course work is lacking and indicate the leveling work (if any) which will be required. Substitution and/or equivalency decisions for the listed prerequisite courses or transfer of any graduate hours must be recommended by the program director and approved by the Dean of Graduate Studies.

Transfer Credit

Work completed before the student applies for admission at HSU, or completed another institution after admission to HSU may transfer if:

  1. it is graduate work from a regionally accredited institution of higher education
  2. an official transcript of the work is on file in the Office of Graduate Studies
  3. the work was completed during the last 10 years; and
  4. it is approved by the appropriate program or department. A maximum of six semester hours may be transferred from a previously completed degree.
