Research on risk assessment and risk management in offenders with intellectual disabilities (OIDs), although far behind compared to the mainstream offender literature, is now expanding. The current review provides an overview of the predictive value of risk assessment and treatment outcome monitoring tools developed for both mainstream forensic populations and OIDs. It is suggested that "mainstream" instruments have equal validity in OIDs, although studies in sex offenders show mixed results. In order to tackle specific criminogenic needs, unique characteristics of OIDs and their environment should be taken into account, which are addressed in ID-specific tools. Evidence regarding the added value and validity of these tools is however still preliminary.
