This article provides a brief history of K–12 education testing in the United States from colonial America to the present. In early America, students were examined orally. After the mid-nineteenth century, written tests replaced oral presentations. In the late nineteenth century, graded schools gradually replaced the single-teacher, one-room schools. In the beginning of the twentieth century, standardized intelligence tests were increasingly used to categorize and promote students. State departments of education have played a larger role in local school funding and policies in the past hundred years. Since the 1960s, the federal government has expanded its involvement in national education while also promoting the role of states. During the past three decades, the federal government and states increased the use of high-stakes national testing with initiatives such as America 2000, Goals 2000, No Child Left Behind, and Every Student Succeeds.
