Sunset Laws - As enacted, extends the board of communications disorders and sciences to June 30, 2031. - Amends TCA Title 4, Chapter 29 and Title 63, Chapter 17.

HB 1558 extends the existence of Tennessee's Board of Communications Disorders and Sciences until June 30, 2031, by amending relevant state codes. This procedural bill directly affects the board itself and professionals regulated under its oversight, such as speech-language pathologists and audiologists. The key provision modifies the board's sunset date in Tennessee law, ensuring it continues operating without needing reauthorization before 2031. The bill makes no substantive policy changes but maintains the board's current regulatory structure. It is a routine extension of an existing administrative body.
