This course is designed for educators who are interested in learning more about how assessment in a differentiated classroom can assist teachers in promoting student learning. In many ways, the goal of using assessment is to help all students succeed and to provide teachers with guidance in designing instruction to meet varied learning needs in their classrooms.

The course uses the ASCD book, Assessment and Student Success in a Differentiated Classroom by Carol Ann Tomlinson and Tonya R. Moon, for its main readings, along with articles and videos that focus on a particular module’s topic. Each module also contains application tasks that will help you use key concepts and practical strategies found in that module. At the end of each module, you can also choose from a variety of prompts to reflect on further implications for your classroom practice and/or to summarize your understanding. Each module also includes a brief quiz that allows you to review what you have learned from the readings.
