It has long been believed that the education system must assimilate new and different groups into American society. Public school assimilation efforts, however, have often been wrenching for students and families, seemingly based on an assumption that some groups will refuse to assimilate or will even rebel against prevailing norms. This worry has animated opposition to school choice and may be particularly acute when it comes to Muslims, especially since 9/11. But are fears that Islamic schools may be failing to Americanize—or worse, are teaching things antithetical to American values—borne out in reality? This new book, incorporating national survey data on Islamic schools, in‐depth interviews with Islamic school leaders, and more, begins to answer that question.
