In the past ten years, chronic absenteeism has attracted increasing attention. Research correlates chronic absenteeism with lower standardized test scores and grade point averages. Chronic absenteeism also correlates with higher rates of grade retention and dropping out (UEPC, 2012). Being present in school is a necessary precondition to receiving instruction and needed supports to help master lessons. As a result, many states now use a measure of chronic absenteeism as a component in the accountability system they use to evaluate their public schools each year. The McKinney-Vento Homeless Assistance Act (McKinney-Vento Act) provides students who lack a fixed, regular, and adequate nighttime residence with the right to the same free, appropriate, public education that other students receive. Each year, to ensure the law is fully implemented by school districts and states, the U.S. Department of Education (ED) collects demographic and academic data on students eligible for services under the McKinney-Vento Act. This brief examines chronic absenteeism among students who experienced homelessness using data from School Years (SYs) 2016-17 through 2018-19, which are the first three years in which the data were collected.
