The SAIC produced the following guiding documentation that will be used by the 15 participating states—and are available publicly—to inform large-scale NGSS test and item development:
- An Assessment Framework that includes the overall test design, description of an aligned test item cluster as the foundational unit of an NGSS-aligned assessment, specifications for various types of test items, and accessibility principles;
- Item Specifications Guidelines that detail a model of NGSS item cluster specifications, classify item types for consideration in an item cluster, identify key elements for each item cluster, and describe the linkage between item clusters and the NGSS;
- Two Item Cluster Prototypes (Grade 5 and High School) that can be used by the participating states to inform test item development. Each prototype includes a description of the cluster’s alignment to performance expectation targets, NGSS dimensions (i.e., Disciplinary Core Ideas [DCI], Science and Engineering Practices [SEP], and Crosscutting Concepts [CCC]), NGSS evidence statements, and a description of how the items are designed to function as a unit.
The states and entity that participated in the Science Assessment Item Collaborative include Arkansas, California, Connecticut, Delaware, Illinois, Kentucky, Hawaii, Maryland, Massachusetts, Michigan, Nevada, Oregon, Washington, West Virginia, and the U.S. Virgin Islands.
The Assessment Framework provides a range of options and accompanying rationales for the development of NGSS-aligned items and summative assessments.
The Item Specifications Guidelines, developed as a companion document to the SAIC Assessment Framework, provides a methodical and practical guide for the development of Item Specifications for the assessment of the NGSS. It discusses issues pertinent to assessment development and provides a road map for the development of clear, comprehensive specifications for NGSS-aligned item clusters.
The Grade 5 Item Cluster 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. The prototype serves as an initial model for measuring the three-dimensional science learning called for in the NGSS and should promote ongoing dialogue about the vision for a truly next-generation science assessment. The item cluster can now be previewed live with interactive items and media.
The High School Item Cluster 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. The prototype serves as an initial model for measuring the three-dimensional science learning called for in the NGSS and should promote ongoing dialogue about the vision for a truly next-generation science assessment.
We welcome your feedback about the Collaborative's framework, guidelines, and prototypes. Please submit comments at the CSAI Contact Us page.
As a follow-up to the resources developed by the CCSSO Science Assessment Item Collaborative (SAIC), WestEd administered a survey designed to capture how states have used the original SAIC materials. This flyer summarizes how use of the SAIC materials has evolved from the original documentation based on the unique needs of each state.
Webinar: Assessment Framework and Item Cluster Prototypes: New Tools to Support NGSS Large-Scale Assessment Development
On September 19, 2016, experts from CSAI and the Washington Office of Superintendent of Public Instruction discussed the development of NGSS-aligned assessment items. This discussion also included information on how the SAIC has informed Washington's development of a state science assessment aligned with NGSS.
