Dropout rate increases

Iowa’s dropout rate also has gone up, according to state data. The dropout rate counts students in grades 9 through 12 — which is why it simultaneously can increase with the state’s graduation rate, which counts only one class of students.

During the 2015-16 school year, 2.8 percent of high-schoolers — about 4,150 students — dropped out.
