Table 4 Changes in student performance on the PACER test, measured in fall (pre) and spring (post), by grade, year, and cohort, for 40 schools providing data on student knowledge and behavior, fitness measurements (BMI, PACER test), HealthMPowers resource usage, and school policies and practices

From: A holistic school-based intervention for improving health-related knowledge, body composition, and fitness in elementary school students: an evaluation of the HealthMPowers program
