The Next Generation Science Standards (NGSS) development involved several rounds of review with multiple stakeholder groups and experts, including a review by the National Research Council, confirming their alignment to the Research Council’s 2011 report, A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas. As per the title, the standards have three dimensions that are integrated in instruction at all levels. Furthermore, the NGSS give equal emphasis to engineering design and scientific practices. Two volumes comprise the NGSS: Volume I provides an introductory section, standards by grade for K–5 and by grade-level spans in 6–8 and 9–12. Ensuing sections identify alignment to the Common Core State Standards, while Engineering practices are found at the end of elementary as standards for 3–5, at the end of middle school's 6–8 standards, and after the 9–12 grade-span standards. The second volume includes appendices to address and highlight key dimensions and their design, the engineering focus of the NGSS, issues of equity, professional development and implementation of the NGSS.
This website is easily navigated and comprehensive in information related to the development process of, explanation of, and access to the NGSS. This resource is relevant, timely, and complete in its presentation of the NGSS. Additional links to supplemental resources are updated regularly. Among the most recently made available are a rubric for lessons and units' evaluation, facilitation guide, examples of classroom tasks, and evidence statements of performance expectations at the high school level. Users wishing to receive email updates are open to subscribe via a provided link. An application has also been made available for mobile devices, so users have ready access to the standards and the three dimensions.
