Training and development practitioners often firmly believe that what they are achieving is worthwhile and valuable, but they lack the methods to provide credible and valid evidence of the impact of their efforts. In this article we demonstrate the use of one method that could assist in this regard, namely the Success Case Method (SCM), developed by Brinkerhoff(1983, 2003, 2005, 2006a, 2006b). The SCM was used to evaluate the CTP described above, and provided practically useful, and reliable information about the programme.
