Trends and Developments in Program Evaluation in General and Criminal Justice Programs in Particular

The paper first describes general trends in evaluation in (mainly) western societies. Why is evaluation growing, what are the characteristics of this ‘growth industry’ and what developments are occurring outside western societies? Trends in the evaluation of criminal justice programs in the USA, the UK and the Netherlands are then discussed. Two important developments are therafter highlighted: experimental evaluations and theory-driven evaluations. Both approaches are discussed, and some pros and cons are listed. Finally, the paper outlines some challenges for future work in the evaluation of criminal justice programs, stressing the importance of combining good designs with both program and social science theories.
