Pre-Environmental Studies

Purdue offers more than a dozen environmental science majors in the colleges of Agriculture, Science, Engineering, and Health and Human Sciences. Each is distinctive, and choosing the right fit for your specific interests can take time.​

The Pre-Environmental Studies program allows students to explore their options before declaring a major at the end of their first year. At the same time, they take courses in introductory environmental science, biology, and communication to stay on track toward a degree in an environment-related program.




Although Pre-Environmental Studies is housed in the Natural Resources and Environmental Science program, Pre-ES students are exposed to all of Purdue’s environmental science majors. They learn about the classes that each major requires and the types of jobs it can lead to. Students can choose any major, as long as they meet its chemistry and math requirements. The Pre-ES advisor works with students individually to help them prepare to select their major and prepare to transfer to their academic home.

As they explore what Purdue has to offer, some students become interested in controlling air pollution; others, in improving soil and water quality in urban and agriculture settings. Some decide they want to eliminate workplace hazards or develop technologies to find beneficial uses of wastes. Still others are drawn to the idea of enhancing ecosystem health, optimizing land use, or crafting policies for long-term solutions.
