Were teachers involved in the creation of the standards?

Yes, teachers have been a critical voice in the development of the standards. The Common Core drafting process relied on teachers and standards experts from across the country. The National Education Association (NEA), American Federation of Teachers (AFT), National Council of Teachers of Mathematics (NCTM), and National Council of Teachers of English (NCTE), among other organizations, were instrumental in bringing together teachers to provide specific, constructive feedback on the standards.
