National Physical Science Consortium

• The National Physical Science Consortium (NPSC) offers two graduate scholarship programs. The Dissertation Support Fellowship offers support for graduate students conducting research for their dissertations. Students should submit applications in the year prior to the start of their dissertation research. Students who do not qualify for this program may qualify for the Traditional NPSC Fellowship, which can provide funding for as long as six years. Students should apply between their senior year and second year of graduate school. Both fellowships are restricted to U.S. citizens and can provide up to $20,000 per year, as of 2011, and a minimum of one paid internship at a government agency during the summer. Applications are available online at the NPSC website between August 25 and November 30, or students who have interned or been employed at a government agency or lab can be nominated directly by their research supervisor or mentor.
  
  

United States Environmental Protection Agency

• The United States Environmental Protection Agency (EPA) offers internships and fellowships for students pursuing degrees in environmental science. The National Network for Environmental Management Studies (NNEMS) is open to both undergraduates and graduate students. Students may complete their research by working part time during the school term and full time during summer months. The deadline for applications is typically during the winter for projects starting the next summer. The EPA also offers the Science to Achieve Results (STAR) fellowship program for graduate students in engineering and science disciplines related to the environment. Support for those seeking a master's degree is limited to two years, while support for those pursuing doctorates is limited to three years with the possibility of a fourth year. Applications are accepted for three months beginning during the summer months. Information on these and other programs can be found at the EPA website.
  
  

American Indian Science and Engineering Society

• The American Indian Science and Engineering Society (AISES) administers the AISES Google Scholarship. Applicants must have at least a 3.0 grade point average, be a member of a Native Hawaiian or American Indian tribe and a member of AISES. The scholarship is open to undergraduates and graduates who are majoring in computer engineering or computer science. Other majors may be considered if the program involves a great deal of computer science research or courses. The deadline for applications is February 15. More information about this and other opportunities can be found at the AISES website.
  
  

The Hertz Foundation

• The Hertz Foundation offers financial assistance for students who are not beyond their first year of graduate school and who are majoring in engineering or biological or physical science. Awards are open to U.S. citizens or permanent residents who will make a moral commitment to offer their expertise to the country in the event of a national emergency. Applications are typically accepted between August and October each year, and students can find application packets on the foundation's website.
  
  

U.S. Department of Defense

• The Department of Defense awards approximately 200 fellowships to graduate students annually provided funds are available. Candidates for the National Defense Science and Engineering Graduate (NDSEG) Fellowships must be pursuing a doctorate in an area of interest to the Department of Defense, such as engineering, chemistry, life sciences, behavioral science, oceanography and physical science. The awards cover all tuition and fees as well as a monthly stipend that ranges from $30,500 to $31,500 per year. Application deadlines are typically in mid-December each year. To submit an application or for more information, visit the NDSEG website.
