It is essential that undergraduate biology majors are made aware of and receive guidance on career possibilities. The authors, who actively advise and teach biology majors (and future majors) at both the high school and undergraduate levels, collaborated to identify resources and methods to advise biology majors about their career choices. Multiple resources were identified. Current advising theory recommends a method of supporting students to make wise choices by considering personal vision, the kinds of professional successes desired, and individual talent development. U.S. Bureau of Labor Statistics, U.S. Census Bureau, and National Science Foundation data were analyzed to identify potential jobs that biology majors can attain. These resources and strategies should help faculty advisors and instructors inform biology majors about possible career paths.
