CHEYENNE, Wyo. (AP) — Wyoming's high school graduation rate fell to 78.9 percent in 2011-12.

Figures released Friday by the Wyoming Department of Education show the rate is down from 79.7 percent in 2010-11 and 80.4 percent in 2009-10. In the 2011-12 school year, just over 5,400 students graduated on time from high school while 1,450 did not.

Washakie County School District 2 in Ten Sleep had the highest graduation rate in the state, with all seven of its students graduating on time. On the other hand, Fremont County District 21 in Fort Washakie had the lowest rate at 11 percent, with just two of its 18 seniors graduating. State Education Department interim director Jim Rose says the statewide rate is distressing but improvement is achievable.
