The DEF is a private, not-for-profit organization founded in 1989 after Proposition 2½ budget cutbacks forced the Duxbury school system to cancel many fine arts and enrichment programs. The DEF receives, administers, and disburses funds for educational, scientific and charitable purposes to be used to develop, support and assist programs which benefit the students, teachers, and staff of the Duxbury public school system.

Managed by a board of twenty-one volunteers, the DEF trustees meet regularly to organize fundraising activities and consider grant applications. Any teacher or administrator in the Duxbury schools, or anyone with a program designed to enrich the educational experience of Duxbury students may apply in writing for a grant. Funds are made available for DEF grants through generous contributions. To raise funds, the DEF organizes fundraisers including the Answer the Call annual appeal, the Polar Plunge and the July 4th Road Race. All donations are tax-deductible per tax regulations.
