This Policy Framework sets out the arrangements, mandatory requirements, and general guidance for use of the OASys Sexual reoffending Predictor (OSP). OSP will replace Risk Matrix 2000 as the HMPPS actuarial risk assessment tool for adult males convicted of sexual/sexually motivated offences from 1 March 2021.

HMPPS plays a vital role in protecting the public from those who pose a risk of sexual offending. Effective risk assessment is a critical part of this process and informs the way in which we manage the risk of harm posed by such individuals. In addition to strengthening risk assessment, OSP will also support more effective risk management and responsive sentence planning for those who pose a risk of sexual harm.
