A pamphlet on how to make use of the results of the Illinois Statewide High School Testing Program in an individual school is presented. The 1973-74 testing program includes tests of academic aptitude, reading comprehension and knowledge, communication skills, and mathematical skills. The program reports contain the raw scores of the students in each school and State percentile scores. The reports also contain a frequency distribution of the scores in each school and some summary statistics. (CK)
