This chapter reports on the parts of the observational study designed to evaluate the extent to which practice at Parish Hall Enquiry by Centeniers complies with what is known about effective practice with offenders. The presence and effectiveness of a number of factors considered to be important in reducing the likelihood of re-offending are incorporated into the observation schedule reproduced in Appendix B. These factors include indicators of pro-social modelling and the level of attention paid to external factors and additional problems associated with the offence, the offender, the victim and the community.
