Annually, ACT provides each state with "The Condition of College & Career Readiness," a report that details the college readiness of students who took the ACT[R] test. This report is a companion to "The Condition of College & Career Readiness." This paper traces the college enrollment, retention, re-enrollment, and migration patterns of the 2010 ACT-tested high school graduates in the state of Arizona. It also provides a snapshot of the impact that benchmark-meeting behavior has on those patterns and, ultimately, on success in college. ACT's research on the knowledge and skills necessary for success in college courses resulted in the establishment of ACT's College Readiness Benchmarks. These benchmarks are ACT subject area scores that represent the level of achievement required for students to have a 50% chance of obtaining a B or higher or about a 75% chance of earning a C or higher in corresponding credit-bearing first-year college courses. The report also provides recommendations for policymakers and retention recommendations for institutional practice. (Contains 4 footnotes.)
