The Ateneo's social projects include the Ateneo-Mangyan Project for Understanding and Development to help the Mangyan indigenous group from Mindoro, the "Bigay Puso" and the Christian Service and Involvement Program for grade school students, and the Damay Immersion and "Tulong Dunong" program for senior high school students. In college, social development is fostered by programs of the Office of Social Concern and Involvement, including house-builds with the poverty alleviation movement Gawad Kalinga and the Ateneo Labor Trials Program tied into junior philosophy classes. Student organizations and offices of the Loyola Schools also operate their own social involvement programs. At the Ateneo Professional Schools, programs and units like the Graduate School of Business' "Mulat-Diwa", the Leaders for Health Program, and the Law School's Human Rights Center and Legal Aid programs aim to form leaders. Other Ateneo initiatives include "Pathways to Higher Education" to help the underprivileged youth and the Ateneo Center for Educational Development which conducts national teacher and principal training programs.
