Learn More About Teaching Fellowship


The experiential learning elements of this program include 3-4 days of pre-semester fieldwork in a grassland environment. Data collected is used in future courses. One-week fieldwork projects take place in Colorado during both the fall and spring semesters.

Externship and Research

Students may choose between an integrated externship or graduate research project, which includes a faculty-directed academic experience in an external environmental, laboratory or field research setting. This component of the program links academic content to your learned experiences and highlights ethical issues in environmental biology.

Frequently Asked Questions

A GRE test score is not required for admission to the Master of Science in Environmental Biology or the Environmental Biology Certificate program.

Yes, but our recommendations vary depending on the program you are completing and the time period over which you wish to complete it.

For students completing the M.S. in Environmental Biology in one year, we recommend students keep work commitments to an absolute minimum (no more than 12 hours per week). The one-year Master of Science program is full time and designed to allow students to complete a master's degree in 10 months. This requires intensive focus both inside and outside of class. In addition, students need to take their externship or research responsibilities seriously. Thus, we very strongly recommend that students keep their outside commitments to a minimum.

For students completing the M.S. in Environmental Biology in two years, we recommend students work no more than 30 hours per week in the first year (keeping overtime to a minimum) and no more than 20 hours per week in the second year. The second year of the program will include a required externship that will require significant time and courses are scheduled during the day. For students that must work 40 hours, we recommend deferring the externship or research until the summer of the second year. This will require a full two years (24 months) to complete the program, but will more reasonably allow someone to continue working full time.

For students completing the Graduate Certificate in Applied Environmental Biology we recommend students work no more than 30 hours per week (keeping overtime to a minimum). Two courses per semester require additional time outside of class that students who work full time may find challenging.

In addition to these general requirements, we also recommend having flexible hours given the collaborative nature of many projects that require group meetings outside of class time. If this is not feasible, students are required to meet asynchronously or through electronic conferencing.

The Environmental Biology course offerings are designed to leave mornings and two full days free to facilitate externship/research activities, work and studying.

The graduate Environmental Biology courses can only be taken as a part of the Graduate Certificate or M.S. degree programs and the course work is not open to additional students. The Applied Environmental Biology Certificate offers a way to take four courses focused on specific skills desired in environmental fields without committing to the full M.S. program. Students who complete the certificate and then wish to complete the M.S. degree can apply to continue taking classes. Given the coordinated nature of the program, we also do not accept transfer credits except in rare circumstances.
