A lack of information, research, and teacher training exists on the effective implementation of Common Core State Standards (CCSS) or other state standards for struggling learners. The pace and standardization of the curriculum are often at odds with the unique learning needs of students from diverse backgrounds. Researchers in one large urban school district conducted a series of focus groups with special educators to identify their perceptions of these standards and the training needs associated with effective implementation of the standards. The results revealed a pressing need for professional development to facilitate effective implementation of the standards for struggling learners in urban settings. Implications for teacher preparation and urban education are discussed.
