(b) To measure the effectiveness of State Goal 20 of the Illinois Learning Standards for Physical Development and Health, beginning with the 2016-2017 school year and every school year thereafter, the State Board of Education shall require all public schools to use a scientifically-based, health-related physical fitness assessment for grades 3 through 12 and periodically report fitness information to the State Board of Education, as set forth in subsections (c) and (e) of this Section, to assess student fitness indicators. Public schools shall integrate health-related fitness testing into the curriculum as an instructional tool, except in grades before the 3rd grade. Fitness tests must be appropriate to students' developmental levels and physical abilities. The testing must be used to teach students how to assess their fitness levels, set goals for improvement, and monitor progress in reaching their goals. Fitness scores shall not be used for grading students or evaluating teachers.
