摘要：In 1997, Florida passed legislation that created the School Recognition Program,
which gives schools letter grades from “A” through “F.” Given the important impact of
these school grades, it is essential to know if a school’s grade depends more on the
intrinsic qualities of the school or on the qualities of the individual students who go to
that school. Using a sample of 15,100 elementary students, our study is an attempt to
determine this.
