The State of Alaska, by some measures the United States' most rural state, has long supported correspondence schools, a popular school choice option available to all students statewide and used primarily by homeschooled students. This paper first explores Alaska correspondence schools in historical context, and then quantifies capture rate, enrollment by race/ethnicity, grade distributions, and cohort graduation rates for the years 2010-17. Findings include a steady increase in the proportion of Alaskan students enrolled in correspondence schools between 2010 and 2017; disproportionate enrollment of Alaskan students identified as White in correspondence schools between 2010 and 2017; enrollment peaks in late high school during 2014-17; and significantly lower 4- and 5-year cohort graduation rates among students enrolled in correspondence schools compared to those enrolled in traditional public schools.
