Section 1202: EMPLOYMENT OF COACHES
(a) HIGH SCHOOL COACHES.
(1) Full-Time Employees. A school is not eligible for UIL competition in an athletic activity unless the head coach and assistant high school coaches are full-time employees of the school board of the school which the team represents.
(2) Full-Time Defined. Full-time means that the person is under contract to the school board of the school which the athletic team represents for the whole scholastic or calendar year, and the person has enough contractual duties to be considered a full-time employee by the Teacher Retirement System and state law. See Official Interpretation 05-08-03, Appendix I.
(3) Exceptions. A retired teacher/administrator who has 20 or more years of experience may serve as an assistant coach in all athletics and as a head coach for golf, tennis, team tennis, cross-country, track and field, swimming and wrestling. (This rule shall not affect the status of a coach on a leave of absence attending college.) Also, student teachers, while they are assigned to a member school district to fulfill their student teaching requirements, may volunteer to serve as an assistant coach in all athletics. Schools shall not pay student teachers for assisting athletic coaches. A full-time substitute who has coached during the school year may be permitted to continue coaching until the UIL competitive year has ended. Example: state baseball playoffs.
So if you attempt to use volunteer coaches who do not meet the exemptions, then according to this the whole team would be ineligible. So while you may have people volunteer, you are in violation of rules and could be sanctioned.
