As professional learning director in California's Palo Alto Unified School District, Kelly Bikle attended a California Assessment of Student Performance and Progress Institute (CAASPP) workshop with a district team composed of our assessment coordinator, a special education inclusion specialist, and several teachers. The goal was to learn about the Smarter Balanced test, as well as strategies and best practices for using CAASPP to improve teaching and learning. In this article Bikle describes how those ideas led to the creation of a blended professional learning course, Supports for All Students. There are three modules in the course. As participants work through them, they take on increasing responsibility for guiding their own learning and applying what they learn to their teaching context.
