Abigale Koch of Gearhart was among just over 370 graduating high school seniors who have now joined a growing alumni base of Oregon Connections Academy, the state’s largest virtual school. Several hundred families, friends and classmates attended the 10th Oregon Connections Academy graduation ceremony earlier this month. The tuition-free online school held an in-person commencement for its 10th senior class on June 9 at the State Fairgrounds in Salem.
