Offenders are generally considered to be sex offenders if their current offense is a sex offense, if they have a prior sex offense, or if they admit to participating in criminal sexual behavior. The adult criminal justice system in Texas is responsible for supervising at least 38,650 felony sex offenders; these amount to 9.7 percent of the felony population. Eighty-four percent of the Community Supervision and Corrections Department (CSCD) Judicial Districts require treatment as a standard condition of community supervision for sex offenders. Ninety-five percent of required sex offenders are registered; 90 percent of parolees were registered in 1997. Ninety-three percent of the sex offenders who were on parole on August 31, 1998 and were required to attend the treatment program were actively participating. Forty-nine percent of the CSCDs have specialized supervision as a standard condition of community supervision. Approximately half of the CSCD Judicial Districts require sex offenders to be screened and assessed to identify their treatment needs as a standard condition of community supervision. A review of the national sex offender treatment models and the Texas programs indicates that the TDCJ has implemented crucial strategies suggested by experts.
