Internship with DEP

The Department of Environmental Protection has a limited number of unpaid internships available for students to help further enhance their skills and career goals. Internship assignments will be developed in an effort to combine the applicant’s interests and goals with the Department needs.

Our intent is to provide interns with real-world experience and training while at the same time obtaining much needed help on our most pressing challenges.

The vast majority of our internships are suitable for undergraduate or Master’s students, but qualified high school students may be considered. Internships can be limited to a semester or year-round, except for the biological monitoring internships which are only in summer. View our Do’s and Don’ts of applying for an internship.
