The resource seeks to focus both educators and curriculum developers on the critical innovations within the NGSS and dig deeply into materials to (1) evaluate the presence of those innovations and (2) answer the question "How thoroughly are these science instructional materials designed for the NGSS?" Educators can use PEEC to evaluate the NGSS design of comprehensive science instructional materials programs that include different units, kits, modules, textbooks, textbook series, and/or web-based instructional materials, including open educational resources.
