Although Oregon has made recent gains in its overall high school graduation rate, 21 percent of public school students entering grade 9 in 2014 did not graduate within four years, by 2018. To improve graduation rates, Oregon voters approved Ballot Measure 98 in 2016 to fund dropout prevention and college and career readiness initiatives in high schools. Many districts used the additional funding to adopt an early indicator and intervention system (EIIS). Districts can use an EIIS to identify students who are not on track to graduate on time by monitoring related indicators, such as chronic absenteeism, disciplinary infractions, course progression, and academic performance, through a frequently updated data system. After identifying students who are not on track, educators assign interventions designed to support the specific challenge students are experiencing, such as daily first period check-ins to address chronic absenteeism. Districts then monitor student response to interventions and modify supports as needed. This Study Snapshot highlights key findings from a study that provides information to the Oregon Department of Education and Oregon districts that are adopting or considering adopting an EIIS, as well as to other interested state and district education leaders who are considering a similar system.
