The Hudson School has a strong tradition of community. High school extra-curricular activities include service to Habitat for Humanity, in which students work on weekends to build homes for the homeless, and Amnesty International. All high school students perform at least twenty hours of community service each year, including work for food drives, clothing drives, and neighborhood clean-ups. Many middle and high school students participate in the St. Jude Children's Hospital "Math-A-Thon" and other charitable activities. Parents voluntarily coach sports teams, participate in choral and theatrical groups, and serve as tutors and mentors.
The Hudson School's strong performing and dramatic arts programs culminate in several plays and concerts each year. The school has worked with Stevens Institute's Dramatic Society, and received national recognition for the collaboration. The Hudson School has also received numerous grants from the Hudson County Division of Cultural and Heritage Affairs for its Cultural Outreach Series.
