Yes. I think the cost of an assessment depends upon the infrastructure that exists. If you look at an organization like the Correctional Services of Canada, you see that they have a structured system of assessing risk and also of gathering information that other assessments of risk are based on.
If that kind of system is in place.... It involves probation and parole officers and getting court records and social work input, those sorts of things where you have a very good history of the person, both a behavioural history and a criminal history. If that stuff is all documented and easily accessible, it markedly speeds up assessments and makes them more reliable.
An assessment can only be as good as the quality of the data that it's based upon. If you have an organization that's dealing with offenders, it's critically important that they have a kind of a standardized method of gathering and recording information that professionals can then use in making risk assessments.
