I'll just start with effectiveness of the program. We have some very compelling statistics from our research department showing that the likelihood of someone returning after committing a new offence is reduced by 45% if they have completed one of our substance abuse programs, and by 63% for violent offences. So the programs are very effective at helping offenders build the skill sets they need to manage their addictions or other difficulties and to live in a law-abiding way. We know, though, that anyone recovering from addiction experiences relapse and slips along the way. Those lapses are to be expected. But the effectiveness is demonstrated through the research we've done.
You ask about qualifications. There are various staff doing various things. Obviously the nurses are registered nurses, the psychologists are registered psychologists, and the program delivery officers have qualified through the competitive process. Then they have extensive training to assist them in delivering, for the most part, cognitive and behavioural types of intervention for the offenders.
