Oregon's on-time graduation rate reached 75% in 2015-16, an increase of about 1% from the previous school year. The increase equates to more than 1,300 additional students earning their diploma compared to last year. Nearly all student groups saw an increase in their graduation rate, with Native Hawaiian/Pacific Islander, African American/Black, and Hispanic students, Ever English Learners (students who are now or ever have been classified as English Language Learners) and Students with Disabilities showing the largest gains. Career and Technical Education (CTE) participants and CTE concentrators, an additional student group reported this year, show graduation rates above 85% and 90% respectively. Oregon Department of Education staff spoke with principals from ten high schools that have significantly improved their graduation rates, consistently maintained high graduation rates, or have narrowed the gap in graduation rates among student groups. Summaries that share highlights from these interviews are included.
