Information on college internships with environmental organizations and educational requirements of applicants is presented, based on 1972-1982 data collected on 1,485 projects by the Center for Environmental Intern Programs (CEIP). CEIP is a clearinghouse for several hundred U.S. internships. Data such as year, location, sponsoring sector, number of interns, qualifications, salary, duration of internship, and disciplinary background were extracted, computer coded, and analyzed. Findings include: internship positions through the CEIP program were mainly offered during the summer; many CEIP internship positions required a junior or senior level student; most positions were offered by the government sector (mostly local, regional, and state level agencies), followed by nonprofit organizations and the corporate sector; most internships lasted 12 weeks, with a range of 4 to 52 weeks; most CEIP interns were provided a stipend; many employers defined internships in terms of clearly defined tasks to be accomplished; and only occasionally were positions described with a general environmental studies major in mind. Individual disciplines and application areas for the internships are identified, along with frequency distributions. (SW)
