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 work no more than 16 hours per week (preferably on the weekend). The one-year Master of Science program is full time and designed to allow students to complete a Masters degree in 10 months. 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 40 hours per week in the first year (keeping overtime to a minimum) and no more than 30 hours per week in the second year. The second year of the program will include a required externship that will require significant time. 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 40 hours per week (keeping overtime to a minimum). The accelerated nature of the eight-week sequential courses makes them rigorous such that they will require more time than a single course taken over sixteen weeks.
