Directs the state Department of Education to require all public school districts to take certain actions to manage asthma in the school setting. These actions include implementing an IPM plan, minimizing school bus idling, and requiring local school health councils to develop long range IAQ maintenance plans. School districts are also required to direct local school health councils to adopt and implement a local school wellness policy that addresses: (1) minimizing children's exposure to pollutants that trigger asthma; (2) assessing IAQ and ventilation in school buildings annually; (3) prohibiting the use of hazardous substances such as cleaning products and pesticides while children are present; and (4) ensuring that school construction projects implement containment procedures for pollutants that trigger asthma. Regulations under the law (Miss. Admin. Code t. 7, pt. 8) establish a K-8 Health Curriculum Resource that includes a teacher's classroom checklist with numerous IAQ-related items.
