(a) LEAs are authorized to implement a program that identifies public school children who are at risk for obesity. Those schools systems that choose to carry out such a program shall:

(1) Have sufficient number of current school staff or school volunteers trained in taking a body mass index (BMI) to meet the requirements of this part. The department of health shall develop and provide training materials to the LEAs;
(2) Complete a body mass index for age (BMI-for-age), as defined by the centers for disease control and prevention, on every child enrolled for classes in the school system whose parents or guardians have not requested exclusion from the testing; and
(3) Provide each student’s parents or guardians with a confidential health report card that represents the result of the child’s BMI-for-age screening, along with basic educational information on what the results mean and what the parents or guardians should do with the information.
(b) School systems that carry out the program shall transmit the results of the testing for each student to the department of health.
