A rapid evidence assessment was conducted to provide an updated review of reoffending research on child sexual offenders from January 2010 to March 2020. Thirty-three studies examining 55 independent samples of adult and juvenile child sexual offenders were reviewed.

Across most studies, rates of sexual reoffending were 15 percent or less, and rates of general reoffending were between 20 and 54 percent. The evidence suggests that the cumulative likelihood of both general and sexual reoffending increases until about two to four years after contact with the criminal justice system, then stabilises. Escalation from non-contact to contact sexual offending is not common. Finally, the evidence suggests that juveniles are more likely to reoffend sexually and generally than adults.
