The present study investigates the use of two actuarial assessment measures ‐ Risk Matrix 2000 (Thornton et al, 2003) and Static 99 (Hanson & Thornton, 2000) ‐ with individuals convicted of downloading child pornography on the internet. A UK community‐based sample of convicted internet sex offenders (n = 73) was assessed using both a standard and a revised version of RM2000 and Static 99 and assessed for rates of reconviction. None of the offenders in the sample were convicted of a further sexual crime between a one‐and‐a‐half and fouryear follow‐up. These results suggest reconviction rates for internet sex offenders are lower than for contact child sex offenders. It was found that both the standard version of RM2000 and Static‐99 overestimate the risk levels posed by internet offenders and that an adapted version of RM2000 may be a more realistic measure of risk level in this population. In addition, it was noted that a higher frequency of low‐risk offenders appeared to be accessing images of younger children and images depicting more serious victimisation than high‐risk offenders.
