In 2003, the Ateneo partnered with Gawad Kalinga in its first formal, university-wide social action program. Also, in response to the typhoons and flooding that devastated most of the Philippine Island of Luzon in November 2004, the Ateneo launched Task Force Noah which has continued to contribute to disaster relief and rehabilitation efforts in areas that include Calatagan in Mindoro and Guinsaugon in Southern Leyte. Also in 2004 the Ateneo earned the highest possible accreditation status, Level IV, from the Federation of Accrediting Agencies of the Philippines and the Philippine Accrediting Association of Schools, Colleges and Universities (PAASCU). And the Ateneo celebrated the 145th anniversary of its founding and of the Jesuits' return to the Philippines, even as plans began for its sesquicentennial in 2009.
