The Next Generation Science Standards are currently being revised after an extensive public review in May, 2012. They are scheduled to be released during the 2012-13 school year.

The final draft of the NextGen Science Standards, released Jan. 8, 2013, is available in two formats: By Disciplinary Core Ideas and by Grade Level. Both documents are very large (9 MB) so they take awhile to download.

The Content Framework for the NextGen Science Standards provides the conceptual background for the standards and details the scientific and engineering practices, the "cross-cutting concepts" and the disciplinary knowledge needed at each grade band.
