In 2011, Christina Public Schools and Killeen Independent School District turned to ASCD for solutions to their unique professional development challenges. Christina Public Schools, the largest district in the state of Delaware, opted for on-site capacity building in differentiating instruction. To meet its professional development needs, the Killeen school district, which in large part serves families of armed forces personnel stationed in central Texas, integrated ASCD's PD In Focus® professional development solution into its existing professional learning communities.
Several high-needs New York City schools serving diverse urban learners at the elementary, intermediate, and high school level also began new relationships with ASCD in 2011. They turned to ASCD for long-term, sustainable support that included on-site coaching in areas such as using the Understanding by Design® framework, curriculum mapping, formative assessment, and differentiated instruction. They also came to the association for help developing instructional leadership in administrators and teacher leaders at all levels.
Other districts, such as Cypress Fairbanks Independent School District in Texas, Dougherty County School System in Georgia, and Southfield School District in Michigan, continued to strengthen their relationships with ASCD. Cypress Fairbanks—the third largest district in Texas—entered its third year of ASCD-guided differentiated instruction implementation in all of its Title 1 middle and high schools. Dougherty schools began building capacity with ASCD in 2007 and continue to implement differentiated instruction. Meanwhile, Southfield School District, just outside Detroit, Michigan, continued a multiyear K–12 implementation focused on differentiating instruction.
