1. Each school district is prohibited from administering or conducting an invasive physical examination of a student, or a student health screening that is not required by state or federal law, without first acquiring the written consent of the student’s parent or guardian. This section applies only to a minor child in the direct care of a parent or guardian, and does not apply to an emancipated minor or a minor who is not residing with the parent or guardian.
 2. This section shall not be construed to prohibit a school district from conducting health screenings in emergent care situations or from cooperating in a child abuse assessment commenced in accordance with section 232.71B.
 3. For purposes of this section:

 a. “Emergent care situation” means a sudden or unforeseen occurrence or onset of a medical or behavioral condition that could result in serious injury or harm to a student or others in the event immediate medical attention is not provided. “Emergent care situation” includes the need to screen a student or others for symptoms or exposures during an outbreak or public health event of concern as designated by the department of public health.
 b. “Invasive physical examination” means any medical examination that involves the exposure of private body parts or any act during such examination that includes incision, insertion, or injection into the body, but does not include a hearing, vision, or scoliosis screening.
 c. “Student health screening” means an intentionally planned, periodic process to identify if students may be at risk for a health concern and to determine if a referral for an in-depth assessment is needed to consider appropriate health services. “Student health screening” does not include an episodic, individual screening done in accordance with professional licensed practice.
