H.B. No. 2151 amends the Code of Criminal Procedure to expand the list of offenses that require sex offender registration to include indecent assault and improper relationships between educators and students. Specifically, it modifies the definition of "reportable conviction or adjudication" to incorporate these offenses, ensuring that individuals convicted of these crimes will be subject to the same registration requirements as those convicted of other serious sexual offenses. The bill also introduces new subsections that clarify the registration process for individuals with reportable convictions or adjudications, including those under the supervision of the Texas Juvenile Justice Department.

Additionally, the bill updates the terminology used in the law, replacing references to the Texas Youth Commission with the Texas Juvenile Justice Department. It specifies that the changes in law will only apply to offenses committed on or after the effective date of the Act, which is set for September 1, 2025. Offenses committed prior to this date will continue to be governed by the existing laws. Overall, this legislation aims to enhance public safety by ensuring that individuals convicted of indecent assault and improper relationships with students are included in the sex offender registry.
