The Next Generation Science Standards (NGSS) will replace the current National Science Education Standards and Benchmarks for Science Literacy. The NGSS were developed by the National Research Council, National Science Teachers Association, American Association for the Advancement of Science, and Achieve with input from K-12 teachers, scientists, and other experts. The NGSS incorporate science and engineering practices, disciplinary core ideas, and crosscutting concepts to provide a more balanced approach to science education compared to previous standards.
