NOMIS is currently operating solely as a pilot system in the Isle of Wight cluster. NOMIS holds 1,508 offender records, solely relating to offenders currently held within HMP Isle of Wight. There have been 31 instances of records being incomplete, six instances of inaccurate records due to user error and a further 22 records whose inaccuracy will be resolved by the system being upgraded to the latest version. Incomplete and inaccurate records are less than 4 per cent. of all NOMIS records. The number of inaccurate records is small. Any errors are corrected as soon as they are identified. All systems have processes in place to minimise data input errors.
No information is kept of the number of occasions it is necessary to amend records held on the Offender Assessment System (OASys), which are shared with the offender in order to maintain accuracy. If an inaccuracy is identified, it is corrected immediately.
The Offender Management National Infrastructure (OMNI) is the IT infrastructure used within the National Probation Service: it is not in itself a database and thus does not hold records.
Although there is no process for summarising the number of inaccurate records, HM Courts Service has systems in place to maximise the accuracy of the data held on the Libra system. Any inaccurate records that are found on the system are corrected as soon as they are identified.
