Assessment and testing are two entirely different things. While testing serves as an event to show what a student knows at a given moment, assessment allows teachers to monitor student progress and provide feedback and support that deepens learning. Based on David A. Sousa’s fascinating book of the same name, this four-page quick reference guide gives teachers at-a-glance information on various types of assessment—including preassessments, formative assessments, and summative assessments—along with specific ways to use each type to ensure that all students are learning. It also provides a checklist to help teachers design brain-friendly assessments of student performance.
