DES MOINES, Iowa (AP) — New figures released by the Iowa Department of Education show that the state’s high school graduation rate rose for the class of 2014, making it the fourth straight year the rate has edged up. The data released Wednesday show Iowa’s four-year graduation rate increased to 90.5 percent, up from 89.7 percent in 2013. The overall dropout rate in 2014 was 2.7 percent, slightly down from 2.8 the previous year.

Nine of Iowa’s 10 largest school districts saw their four-year graduation rates climb, with Cedar Rapids Community School District reporting the largest gain of 4.1 percent. Only Sioux City Community School District saw its graduation rate drop.

Statewide graduation rates increased for all but two subgroups of students, with English-language learners seeing the most significant change, a 7.4 percent increase.
