Heights and weights are done yearly on all school students usually in August.  Presently, there is a "...nationwide effort dedicated to improving the health and academic performance of children through better nutrition and physical activity in schools."  As a part of the yearly school health growth screening, measured height and weight will be used as a means of calculating a BMI (Body Mass Index) for a given age. The BMI will be used as a guideline to help assess whether a student may be overweight or underweight.  For more information, go to Body Mass Index for Children and Teens.
