Evidence Centered Design is a process intended to ensure a rigorous framework for developing assessments that actually measure their intended constructs and yield the evidence needed to support claims drawn from the results. In this collection of materials, you will find documents that further explain Evidence Centered Design and its application, including example questions and evidence, a framework for building assessments, and current constraints and recommendations.
The Assessment System Visualizer (ASV) is an online, interactive tool intended to build the capacity of individuals seeking to analyze the components of their state, district, school, and/or classroom assessment systems and make decisions about how to improve them.
CSAI has collaborated with the College and Career Readiness and Success Center and the Midwest Comprehensive Center to develop the Standards Review and Revision Toolkit (“Toolkit”). The Toolkit includes information, examples, and associated resources to help state education agencies (SEAs) execute a research- and best practices-based standards review and revision process. SEAs may utilize the Toolkit as a whole, or reference discrete stages as their context requires.

The Framework is a compilation of ideas and lessons learned from a variety of sources, most recently the Common Core State Standards (CCSS) and the Next Generation Science Standards (NGSS) implementation plans. The Framework provides a general model for implementing new or revised content standards. The Framework is labeled as version 1.0, recognizing that it may evolve and be updated based on user feedback.
On December 10, 2015, President Obama signed into law the Every Student Succeeds Act (ESSA), which reauthorizes the Elementary and Secondary Education Act of 1965. To assist states in the planning and implementation of ESSA, CSAI has created four documents, highlighting key ESSA requirements related to standards, assessment, and accountability, specifically those requirements for which CSAI can provide support to states.
CSAI has collaborated with the Reform Support Network to share this Assessment Design Toolkit. The Toolkit includes v​ideos and supplemental materials to help teachers write and select well-designed assessments. Although the primary audience is teachers and principals, district and State leaders can use the Toolkit to design professional development opportunities.
With the reauthorization of the Elementary and Secondary Education Act (ESEA) through the Every Student Succeeds Act (ESSA), States have an opportunity to reflect on their overall vision and goals for education and determine how to best support that vision to achieve their goals.
The reauthorization of the Elementary and Secondary Education Act, as the Every Student Succeeds Act, continues the requirement for the U.S. Department of Education (ED) to conduct peer reviews of states' standards and assessment systems. This peer review process is designed to ensure that a state's assessment system follows these requirements: 
To assist states as they implement new science standards, the CCSSO Science Assessment Item Collaborative, in collaboration with WestEd, has documented a range of options, accompanying rationales, and item cluster prototypes to guide the development of summative assessments for the Next Generation Science Standards.
Used to support both teaching and learning, formative assessment is an integral component of a comprehensive assessment system. As opposed to summative assessment that evaluates students' mastery of learning goals, formative assessment is continuously used throughout students' learning process to help inform teachers' instruction. The Formative Assessment Bi-Regional Advisory Board is a consortium of seven states that are committed to incorporating formative assessment as a part of their comprehensive assessment system.
