The B.S. Environmental Sciences Degree is broken down into parts.
I. Required Courses: Courses all ES Majors must complete. Some substitutions exist but require special permission.
II. Choice Requirements: Students choose a course or course group according to the requirement rules and prerequisite requirements for elective and focal area courses.
III. Focal Area: Students declare a Focal Area which is an area of specialization within Environmental Sciences. Students work with their advisor to complete courses for their Focal Area, Advised Electives, and Free Electives that further knowledge in your focal area. Your focal area can be based in any department creating a virtually unlimited number of Focal Areas.
IV. External Learning Experience: All ES students complete a total of 3 credit hours of external learning experiences.
Due to the flexibility of the ES Degree, many students pursue minors or a second major. Your minors or second major serve as the basis of your Focal Area. Courses that count towards a minor or second major can also count towards your ES Degree and Focal Area.
