A report from Common Core finds that many of America's high school students do not possess the basic knowledge they need to succeed in the world. The report shows that, twenty-five years after the publication of the landmark study, "A Nation at Risk," America's children continue to demonstrate a stunning ignorance about basic facts of America's history and literature. The survey also identifies a consistent gap--the size of a letter grade--between respondents who have at least one college-educated parent and those who do not.
