Demographic information from the 2010–2011 school year.
Race/ethnic groups with fewer than 5% of students (eg, American Indian, other, declined to state) not shown.
P value for difference in means between specialist and nonspecialist elementary schools calculated by t test; P < .05 indicates significance.
Indicates a significant difference in means between elementary and middle/high schools.
Indicates a significant difference in means between middle and high schools.
The state-wide fitness test, the FITNESSGRAM, uses Healthy Fitness Zones to evaluate fitness performance of fifth, seventh, and ninth graders. These zones are criterion-referenced standards and represent minimum levels of fitness for age and sex that offer protection against the diseases that result from sedentary living. Aerobic capacity reflects the maximum rate of oxygen uptake and use during exercise.
