The Obama administration hopes that states will quickly adopt the new standards in place of the hodgepodge of current state benchmarks, which vary so significantly that it is impossible to compare test scores from different states. The United States is one of the few developed countries that lacks national standards for its public schools.
Students whose families move from New York to Georgia or California, for example, often have difficulty adjusting to new schools because classroom work is organized around different standards. The problem has become worse, since many states have weakened standards in recent years to make it easier for schools to avoid sanctions under the federal No Child Left Behind law.
