Kentucky Education Department officials have released the results of ACT exams administered to high school juniors in the spring.Spokesperson Lisa Gross says this was the first time that a Kentucky junior class took the college-prep test."In 2006, the Kentucky General Assembly amended a state statute that requires all public school juniors to participate in ACT testing, so the first time that this actually happened was in the spring of 2008. The scores that we're seeing today are the first scores from this particular population of kids," Gross said.Statewide, the composite score was 18.3, out of a possible 36.Jefferson County students had a composite score of 18.Gross says the results will be most helpful to individual schools, which can use them to determine if improvements are needed in English, math, reading and science instruction.
