In this article I address some assertions made by one of the most outstanding educational historians, Diane Ravitch, regarding the relation between immigration rates and academic achievement among children in the United States. In her book The Great School Wars Ravitch asserted that low immigration levels during the 1920s to early 1960s period played a large role in producing a golden age of education in New York and probably in the United States. The research undertaken for this article does confirm some of Ravitch's assertions but questions whether other claims of hers may be overly simplistic. Among her assertions that the research supports are that academic achievement rose among New York City elementary and secondary students during this "golden age," children from most immigrant groups did perform poorly compared to children born in the United States, and that the increased volume of enrollment and language factors did exert added pressure on the school system. Nevertheless, other factors lead one to believe that Ravitch's claim, although possessing merit, may be overly simplistic. For example, certain immigrant groups performed very well academically after coming to the United States. This fact supports the notion that the makeup of the immigrant population may be as important as the immigration volume. In addition, the decline in American student academic achievement in the 1960s and 1970s began well before the United States fully liberalized its immigration policy. One would not expect this, if immigration has the level of impact that Ravitch claims.
