America's Story: An Immigrant Story 

America's Story

The United States, throughout its history, has benefited greatly from the arrival of new people who bring with them fresh energy, ideas, and ambition. But immigration also brings thorny questions and political quandaries: Who stays and who goes? Who qualifies to be a citizen and who decides? Earning citizenship takes years, and even when it is achieved, it is not the end of the story. Andrew Carnegie was resolute in his belief that American democracy thrives only when citizens participate actively and knowledgeably in civic and political life. Integrating and empowering new Americans is central to the mission of Carnegie Corporation of New York. The Corporation supports grantees who are encouraging citizenship and civic participation and working on strategic communications, effective policy solutions, and grassroots coalition building. Learn more about America's Story: An Immigrant Story.

The Opportunity Equation

America's Story

Carnegie Corporation, together with the Institute for Advanced Study, organized the Commission on Mathematics and Science EducationIn 2009, the commission issued its report, The Opportunity Equation: Transforming Mathematics and Science Education for Citizenship and the Global Economy. Today, that movement is retooling the education system to provide excellent math and science learning for all students, not just those fortunate enough to attend high-performing schools. The changes now underway will enable more students to enter STEM fields, and at the same time better prepare all students for college and a career. The hope is that making math and science learning central to education will strengthen the educational system overall. Learn more about The Opportunity Equation.
