Environmental Science Program

The goal of Hardin-Simmons Department of Geological and Environmental Sciences is to teach our students a solid foundation in the various geoscience disciplines. Our department provides fundamental training for career geologists and environmental scientists, introduces a basic understanding of the environmental science for our liberal arts student. Our program is designed to prepare students for graduate school and professional work in the environmental sciences.

Grad School Preparation

The Environmental Science program prepares students for graduate and professional careers. Our graduates have successfully been admitted to doctoral programs in environmental science, environmental health, Library Sciences, Law (J.D.), and many enter the HSU Environmental Management Master of Science program. Graduates of our program have succeeded in a wide range of professional career paths such as Texas Commission for Environmental Quality, Texas Railroad Commission, private sector environmental regulations careers, and have pursued additional environmental graduate work.

Personal Attention

Our small class sizes provide students with many opportunities to learn from faculty both inside and outside of the classroom. Your professors will know your name. We are invested in your success. We can add great depth to letters of reference or recommendation! Our graduates are successful at seeking and entering further graduate work, including doctoral studies, and career paths.

Excellent Outcomes

All of our environmental science graduates have a landed meaningful employment in the field within six months of graduation or have continued their academic preparation with doctoral studies, other master’s work (Library Studies), or entered the HSU Environmental management master’s program. Students moving on to graduate programs have been accepted at the University of North Texas, University of Texas – Arlington, Texas Tech, and the University of North Carolina at Chapel Hill. About 60% of our graduates are admitted to the HSU Environmental Management Master of Science program.

Program Details

The Bachelor of Science in Environmental Sciences

The Bachelor of Science in Environmental Sciences major requires a minimum of 35 semester credits (28 of which must be upper-level courses in Environmental Science). A Bachelor of Science degree is recommended for students interested in pursuing a career in the environmental sciences, to sit for the Registered Environmental Manager’s (REM) examination, or to pursue a graduate degree in environmental sciences (or management).

Courses required include ENVS 1311/1111, 2311, 3308 or 3309, 4144, 4308, 4311 (or ENVM 5311), 4312, 4316, GEOL 3311, ENVM 4340, six credits from BIOL 3410, 4405, or GEOL 4315.

Required supporting courses include: CHEM 1310, 1110, 1311, 1111, PHYS 1310, 1110, 1311, 1111; one of two mathematics options as either MATH 1420, 1421 and MATH 3312, or MATH 1310 and 1311, and STAT 3312. The choice of the minor is restricted to Biology, Chemistry, Geology, Computer Science, Mathematics, Physics, or Public Health.

A major in Environmental Science must pass all required, elective, and supporting courses with grades of “C” or better in order for the Department Head to certify that a student has been offered the academic background needed to sit for the REM examination. The Registered Environmental Manager’s examination is rigorous and has a five-year practice requirement. A student who anticipates sitting for the examination should work to earn the highest grades possible in all science and supporting courses. This gives the student the best potential to pass the examination.

  • Our graduates have the opportunity to prepare for the Registered Environmental Manager (REM) examination
  • All graduates of our program have either moved to professional environmental-related careers or have continued with graduate studies
  • Our graduates are working to make our world a cleaner and safer place
  • Our students are prepared to contribute to our world as caring Christian Environmental Scientists
