On behalf of the Council of Chief State School Officers (CCSSO) Science Assessment
Item Collaborative (SAIC) state members, WestEd’s science content and assessment
specialists are pleased to present this Grade 5 Item Cluster Prototype for assessment of
the Next Generation Science Standards (NGSS). This prototype was designed to follow
the principles and recommendations set forth in the SAIC Assessment Framework and
Item Specifications Guidelines for an NGSS-aligned large-scale summative assessment
item cluster. This first iteration of the item cluster prototype has undergone many rounds
of refinement, and its developers are optimistic that, if it is considered in conjunction with
key sections of the Assessment Framework, it will serve as an initial building block for the
development of large-scale summative assessments measuring the NGSS.
