From Chicago Tribune:

The ACT exam, a critical requirement for getting into most colleges and given free to high school juniors, will become optional in 2015 for the first time in nearly 15 years, with districts given the choice to administer the ACT as well as job-related exams in reading and math skills. All high school students will have to take new state tests in Algebra 2 and English Language Arts in the spring. Both exams will generally be taken by juniors, but could include sophomores in advanced classes.
