Education Commission of the States has researched how states use college-readiness assessments to make the most of the 12th-grade year in all states. This interactive resource provides links to the 50-state comparisons showing how all states approach specific 12th-grade transitions policies: (1) Determinations; (2) Intervention; (3) Acceleration; and (4) State College-Readiness Definitions and Postsecondary Admissions/Placement. A link to the data points for all states and a key findings summary are also included.
