Relating to the program of internal auditing conducted by state agencies.
HB 3666 requires all Texas state agencies to implement a standardized internal auditing program. It mandates that agencies create annual risk-based audit plans and conduct periodic reviews of three key areas: financial systems, operational controls, and information technology systems. The bill defines internal auditing as an independent process to evaluate controls and improve organizational effectiveness, without adding new funding or altering existing audit types. This applies directly to every department, board, or commission in the Texas executive branch.
