Meeting the unique and diverse needs of students challenges educators daily. And, the demand for improvement increases at the same pace. Enormous efforts are underway in school systems and state agencies across the country to design and implement multiple, high-stakes changes in educator effectiveness systems, college- and career-ready standards, and assessments. These changes bring both anticipation for promising results for all students and anxiety about implementing such profound change in such a short time. Along with broad-based support for these changes are debates in schoolhouses and statehouses about the scope, speed, and costs of the changes. Policy makers, decision makers, elected officials, and educators themselves agree that full implementation of the college- and career-ready standards, resulting new curricula, new assessments, and educator effectiveness systems requires extensive professional learning. With the timeline narrowing for full implementation, the degree of change expected substantial, and the pace of implementation efforts accelerating, schools, districts, and states must move quickly and decisively beyond awareness building into practice changing professional learning to prepare and support educators for the transformation.
