A 2013 report finds that most states’ college- and career-readiness accountability systems have focused on getting students to a minimum level of proficiency. The report finds that a coherent college- and career-readiness accountability strategy "centers on the need for states to make ambitious but achievable progress in student performance at a much higher level than minimum proficiency." It recommends states incorporate indicators that measure students’ college and career readiness and use them in multiple ways to orient the system toward postsecondary success.
