Each of the four official class governments (Sophomore and Junior Steering Committees and the Freshman and Senior Senates) makes significant annual donations to various philanthropic causes throughout the community, state, country, and world. Every year since 2001, the Senior Senate has fully funded the construction of a house in conjunction with Habitat for Humanity of Lake County, Illinois, a non-profit organization that fights homelessness and substandard housing. A recent goal of the campaign was 10 houses in 10 years, and the class of 2010 fulfilled that goal. New Trier is the only school so far to build 10 houses with Habitat. Many fundraisers contribute to this and various other causes over the course of the academic year. The New Trier Tsunami Relief Committee donated more than $18,000 to relief organizations to save people who were affected by the tsunami, and also helped victims of the Indian Ocean tsunami in December 2004.
