Texas Health and Safety Code - HEALTH & SAFETY § 36.005. Compliance With Screening Requirements

(a) An individual required to be screened shall undergo approved screening for vision and hearing disorders and any other special senses and communication disorders specified by the executive commissioner.  The individual shall comply with the requirements as soon as possible after the individual's admission to a preschool or school and within the period set by the executive commissioner.  The individual or, if the individual is a minor, the minor's parent, managing conservator, or guardian, may substitute professional examinations for the screening.

(b) An individual is exempt from screening if screening conflicts with the tenets and practices of a recognized church or religious denomination of which the individual is an adherent or a member.  To qualify for the exemption, the individual or, if the individual is a minor, the minor's parent, managing conservator, or guardian, must submit to the admitting officer of the preschool or school on or before the day of admission an affidavit stating the objections to screening.

(c) The chief administrator of each preschool or school shall ensure that each individual admitted to the preschool or school complies with the screening requirements set by the executive commissioner or submits an affidavit of exemption.
