HB 619 allows high school students under the age of 19 to transfer between school districts once during their high school years for athletic participation purposes. The receiving district and the student’s guardians must approve the transfer, which remains valid until the student graduates unless they withdraw. The bill also prohibits penalties or sanctions by the University Interscholastic League (UIL) against transferring students or their new districts, provided the transfer meets legal requirements. This measure supports student mobility while addressing fairness in athletic opportunities​.
