Each score represents a student and each data set represents a school, district, or state made up of dedicated teachers and diverse learners. Our goal is to provide educators and families with the information they need to make decisions about next steps in a student's learning journey. We provide tools for your state's analysts, test providers, and just about anyone interested in "looking under the hood" to better understand how the test works to deliver valuable information about student learning.
