This report examines Alaska public high school graduates' decisions to attend postsecondary education (including workforce training or college), attend in-state or out-of-state colleges, and to remain in or return to Alaska. Three groups of high school graduates' decisions are summarized to maximize the benefit from available data in the Alaska Education and Workforce Outcomes Database. The largest group -- graduates from the Classes of 2006-2013 -- were studied to determine the percentage who attended college or in-state workforce training programs, the probability of students' deciding to enroll in postsecondary education, and the likelihood of students deciding to enroll at either in-state or out-of-state institutions. The second group summarized consists of graduates from the Classes of 2011-2013 because the Class of 2011 was the first with the opportunity to become eligible for the Alaska Performance Scholarship (APS). Data on APS eligibility from students' achievement in high school provides an opportunity to understand whether high grades and test scores are associated with increased postsecondary enrollment or the choice to attend out-of-state colleges. The third group (Classes of 2006-2009) examines students' decision to stay in Alaska after high school until 2014 or, for students who left for out-of-state colleges, their decision to return to Alaska afterwards. Key findings from this analysis include: (1) Out of Alaska's public high school graduates from the Classes of 2006-2013, two-thirds chose to attend postsecondary education (college or Alaska workforce training programs); (2) A majority of the students who attended postsecondary education chose to enroll in Alaska institutions (53%), 29% chose to attend out-of-state institutions, and 18% had mixed in-state and out-of-state attendance after high school graduation; (3) Students eligible for Alaska's merit scholarship, the Alaska Performance Scholarship (APS), were more likely to attend college out-of-state; (4) Alaska Native students and students from low-income families were more likely to stay in Alaska after high school. (5) Among students who attended the University of Alaska (UA), students who earned a UA Scholars award were twice as likely to stay in Alaska as their peers; (6) There was a decline in Alaska residency rates measured the year after students left college, from 79% for students who left in 2007 to 64% for students who left in 2013; and (7) College graduates who earned a credential were less likely than non-graduates to return to Alaska after attending out-of-state colleges.
