A Framework for K-12 Science Education:
Practices, Crosscutting Concepts, and Core Ideas

 Framework Report Cover





Report Brief




The framework identifies the key scientific ideas and practices all students should learn by the end of high school. Designed to make science education more closely resemble the way scientists work and think, the framework envisions that students will gradually deepen their understanding of scientific ideas over time by engaging in practices that scientists and engineers actually use.

The framework is also designed to be useful for curriculum and assessment designers, teacher educators, and others who work in K-12 science education.

Literacy for Science
 The framework served as the basis for the Next Generation Science Standards, which were developed by a consortium of 26 states. The standards provide a detailed description of the key scientific ideas and practices that students should learn as they progress from kindergarten through high school. 

Implementing a new vision for how students should learn about science will require new kinds of assessments.  Developing Assessments for the Next Generation Science Standards recommends strategies for assess student progress in learning science as laid out by the Next Generation Science Standards.

Common standards in K-12 education in key subjects – mathematics, English/Language Arts, and science -- have been developed separately in recent years, but there are areas where these standards overlap across subject areas. The Board on Science Education held a two-day workshop in February 2014 that brought together experts in science education and language arts education to discuss these issues. Literacy for Science summarizes presentations and discussions at the workshop.
