11. Student Employment Programs at NOAA • Student Educational Experience Program (SEEP) • Student Career Experience Program (SCEP) - SCEP is a program that provides experience that is directly related to the student’s educational program and career goals. SCEP replaces the Cooperative Education Program (COOP). Agreements are made with an accredited school combined with periods of career-related work in a Federal agency. Students earn federal benefits. Students interested in applying for a SCEP position should contact the Cooperative Education Coordinator at their school. • Student Temporary Employment Programs (STEP) - Does not have to be in your career field. The position is not to exceed one year with incremental extensions. It is great for career exploration.

12. Student Employment Programs at NOAA • NOAA Faculty and Student Intern Research Program administered by the Oak Ridge Institute for Science and Education (ORISE): • Ten week faculty and student intern research program. Primary focus to provide work experience to faculty, graduate and undergraduate students under represented in mission-related occupations. FTE neutral. • NOAA’s Educational Partnership Program • Sponsored by the NOAA Diversity office and funded by Congress. Students are recruited from Minority Serving Institutes. Salary and graduate school tuition are paid for while attending school. • Workforce Recruitment Program • The WRP is a resource for federal agencies nationwide to provide employment opportunities for qualified students with disabilities. FTE neutral. • For more information on all programs • http://www.weather.gov/eeo/StudentResearchOpportunities.htm
