In 2004, the Senior Scientists and Engineers (SSE) and AAAS formed the AAAS/SSE STEM Volunteer Program to support K-12 STEM (science, technology, engineering, and mathematics) education, foster STEM literacy, and motivate students to pursue STEM careers.
The Program recruits volunteers from the science, engineering, and medical communities in the Washington DC Metro area. It is based on RE-SEED  and TOPS , volunteer efforts launched in the 1990s. The Program began in 2004 in Montgomery County, Maryland and has expanded to schools in Virginia (Fairfax, Loudoun, and Prince William Counties and the cities of Arlington and Falls Church), in the District of Columbia, and in Prince George's County, Maryland. 150 volunteers participated in the 2014-2015 school year. The majority of volunteers are retired, but the number of those still working is growing.
Volunteer assignments are based on individual preferences, teacher requests, and commuting distances.
Once assigned to a classroom, a volunteer may:
"The volunteers have been instrumental in encouraging students to think about their future as scientists. Their generosity is greatly appreciated.”
"There was an air of excitement and intellectual interest that even my reluctant learners responded well to. Having another perspective on making science relevant has the students' attention and they got a lot out of it. (Yes, it was FUN!)"
"The students (at first) viewed me as a real, living scientist who knew all. They have learned from me that one of the beauties of science is that it is a constant learning experience and that we, as scientists, surely don’t know everything!"
"I went to school…and had a blast! … I explained Mendel, his job, and how science begins with observations. In Mendel's case, how did pea plants with purple flowers produce offspring with white flowers? As in, 'WOW! How did THAT happen?'"
"Dealing with students and with the teacher is…rewarding as they truly appreciate my presence and effort. I was asked to talk during Career Day and many of the students have stopped me in the school hall to talk to me."
