Accessibility Committee


The TDD/TTY Accessibility Checklist can beused as a tool in the self evaluation process required of all agencies. Developedoriginally to assist agencies in Texas, this document incorporates requirements foundwithin the ADA and common areas found within settlement agreements. Once you havecompleted the checklist, you will have a better idea of areas that may need furtherattention. Established operating procedures and a comprehensive training program are keyto a successful emergency response system. It also reflects the agency’? commitmentto the protection of lives and property in the community it serves. It is recommended thatyou maintain documentation of your evaluation process. And if, at some time, your agencyis contacted by Justice, you will have answers readily available.
