Compare environmental sciences with other OSU online programs

Check out this degree comparison table to evaluate how environmental sciences compares to fisheries and wildlife sciences, rangeland science, natural resources and other similar online programs. The environmental sciences degree focuses on a strong foundation in math and science and on hands-on field research; as a result, the traditional science coursework requirement is considerable. 

Be prepared for math. In order to succeed in the degree program, students must pass and be proficient in fundamental mathematics, including calculus. We encourage students to complete their math requirements prior to starting this program.

Some of the degree requirements can be transferred from other colleges and universities. Please note that a minimum of 45 credits of the last 75 must be completed at Oregon State (online or on campus) to meet the academic residency requirement.

Previously earned credits will need to be reviewed upon admittance into OSU for appropriate articulation. Additional information about transferring credits is available through the single-course search tool provided by OSU's Office of Admissions.
