National initiatives to raise K-12 standards and align them to postsecondary entrance requirements have prompted states and/or state postsecondary systems to enact policies to improve alignment among postsecondary readiness standards, postsecondary placement and diagnostic exams, and developmental education curricula. This report examines how six community colleges--three each in the states of Florida and Virginia--responded to the state-wide reform of college placement and diagnostic testing. It is a companion piece to "From Policy to Practice: Tracing the Development and Implementation of Placement and Diagnostic Assessments across States, Systems and Community Colleges - Analysis of Policy Reform in Five States" (ED553141) that provided an analysis of how five states commissioned vendors to develop new placement tests that include a diagnostic component. Analysis in this report provides a comprehensive picture of state policy reform by tracing implementation through multiple levels--beginning most broadly at the state level and progressing through increasingly granular levels of implementation. Appendix A provides case studies and Appendix B presents "Local and Community College Characteristics."
