THE NATIONAL CRIME RECORDING STANDARD
As a result of the findings from the DiRCS project, the National Crime Recording Standard (NCRS) was developed to address the lack of uniform practices in initial police recording processes. The NCRS, comprising a uniform set of business rules and requirements, was developed in collaboration with police agencies across Australia to guide the recording and counting of criminal incidents for statistical purposes.
As part of an evaluation of the implementation of the NCRS and statistical impacts visible in the Recorded Crime – Victims collection, the ABS compared these data with state and territory data obtained from the Crime Victimisation Survey, observing that the assault data provided by police still had residual differences between jurisdictions that affected comparability. Through discussion of different business and recording practices with state and territory policing agencies, it was determined that one aspect of the NCRS had been interpreted and implemented differently across jurisdictions. This rule concerns the point at which the incident should be recorded by police in crime recording systems.
Differences in the interpretation of the National Crime Recording Standard (NCRS)
While the application of the rules and requirements of the NCRS were designed to enable the recording of crime in a comparable manner across the jurisdictions, there is some variability in the interpretation of the rules, in particular the rule which guides what is recorded on police systems when an incident is reported to police.
An incident will be recorded as one or more offences if prima facie (on the face of it) and on the balance of probability (more probable than not):
This rule provides a common basis for recording an incident with one or more offences according to the judgement of the police officer (as distinct from evidentiary or prosecutorial reasons).
This rule is intended to guide what is recorded on the police systems when an incident is reported to police. This rule has been interpreted and implemented by New South Wales, South Australia, Australian Capital Territory and Western Australia as requiring that when a victim reports an incident to police this report is taken at 'face value' and recorded as an incident on their crime recording system. An investigation will follow to determine whether a crime has been committed at law. For more information about NCRS impacts on the Recorded Crime – Victims collection, see paragraphs 43–47 of the Explanatory Notes. Note that there are different degrees to which this approach is applied across these jurisdictions.
These issues of lack of comparability between jurisdictions apply only to assault and therefore cross-jurisdictional comparisons can be made for all other offence types in this publication. Issues around assault comparability are specific to this offence, due to a range of reasons:
All of these factors can result in different counts for assault depending on when in the investigative process (before or during) a decision to record is made.
