From Education Week:

On December 17, a panel of the National Research Council (NRC) proposed that states design testing systems that integrate several key types of science learning, and blend classroom-based assessments with state-level “monitoring” tests and gauges of students’ “opportunity to learn.” The proposal offers the panel’s ideas on how testing should change to reflect the Next Generation Science Standards (NGSS). Instead of focusing on students’ knowledge of science facts, the NRC suggested assessment that would draw students into creating scientific models and generating and analyzing data, while also using state-level monitoring and looking for resources that affect students’ abilities to learn science in the ways set out in NGSS.
