Teacher professional development (PD) is a complex, ongoing challenge as educational systems attempt to deliver excellent programming in pursuit of increased student achievement (Opfer and Pedder 2011). This article examines Idaho Total Instructional Alignment (TIA), a model for teacher PD that is currently being utilized in secondary schools throughout the state of Idaho. The implications of this model for effective guidance and support with implementation of the Common Core State Standards (CCSS), as well as the factors that indicate readiness of secondary teachers for implementation of the CCSS, are explored.
