The American Federation of Teachers is a strong supporter of national standards and has been for many years.

Soon after the release of the Common Core State Standards, the AFT emerged as one of its strongest advocates.

Randi Weingarten, president of the AFT, contends that the standards are valuable but the implementation has proceeded without adequate preparation. Last year, she called for a one-year moratorium on Common Core testing until teachers had time to learn the standards, resources with which to teach them, and time for students to learn them. She told a breakfast meeting of the Association for a Better New York, attended by the city’s civic and political elite, that the standards would fail unless implementation was done appropriately, with enough time for teachers and students to prepare for the demands of the new standards.

In the current issue of the AFT journal, American Educator, the AFT educational issues department published a memorandum called “Debunking Myths of the Common Core,” and responded to each of them in turn.

For example, the article maintains, it is a myth that the standards tell teachers what to teach. It is a myth that the standards are a national curriculum. It is a myth that the standards were imposed by the federal government and are mandatory. Etc.
