BCISD follows the Texas Department of State Health Services recommendation for immunization compliance in order for a student to attend school. The law requires that all students be as up-to-date as medically feasible in order to attend classes. The immunization vaccine requirements for each grade level are listed on the Katy ISD website. Exemptions to the immunization requirements are allowable on an individual basis for medical contraindications, reasons of conscience-including religious belief, and active duty with the armed forces of the United States. For further information, visit the Texas Department of State Health Services.
