Chicago Tribune: Illinois ACT scores post biggest drop in a decade

Illinois experienced the steepest drop in a decade in its average ACT score after the testing company decided for the first time to include low scores that it previously excluded.

With the release Wednesday of national and state results for the class of 2013, the testing giant acknowledged that for years it excluded scores of students allowed extra time to take the college entrance exam, an accommodation granted by ACT to those with various disabilities.

Illinois had the largest percentage of those test takers — 10 percent — in the country, according to ACT, so it was hit hard by the inclusion of results for such students, officials said. Nationwide, 4 percent of students got extra time on the test.
