How can I find out about national educational standards and curricula in particular academic subjects?
Some national professional or educational policy organizations have suggested standards and curricula, but there are no federal national standards for any academic area.
Education is mainly a state and local responsibility in the Unites States. When the Department of Education was created, Congress made clear that the secretary of education and other Department officials be prohibited from imposing "any direction, supervision, or control over the curriculum program of instruction, administration, or personnel of any educational institution, school, or school system." (20 USC 3403) The establishment of schools and colleges, the development of curricula, the setting of requirements for enrollment and graduation - these are responsibilities handled by states and communities, as well as by public and private organizations. They are not handled by the U.S. Department of Education.
It is left to the states to create standards while States and local agencies develop curricula. To determine specific standards or curricula in your state, please contact your state department of education.
