The Next Generation Science Standards is a multi-state effort in the United States to create new education standards that are "rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education." The standards were developed by a consortium of 26 states and by the National Science Teachers Association, the American Association for the Advancement of Science, the National Research Council, and Achieve, a nonprofit organization that was also involved in developing math and English standards. The public was also invited to review the standards, and organizations such as the California Science Teachers Association encouraged this feedback. The final draft of the standards was released in April 2013.
