Reviews of research on the evaluation of career assistance from 1970 to 2014 (N = 23) are examined for common conclusions and recommendations. Conclusions are tempered based upon the small numbers of studies included. Recommendations for strengthening research using integrated treatment chains and incorporating epidemiologically based statistics (i.e., risk ratio, odds ratio, and population attributable fraction) are described. A shift in prevailing research paradigm from an emphasis on the individual to an emphasis on the community would supplement evaluations based upon individual outcomes and make a more compelling case to policy makers and funders who could support future evaluative research and provision of career assistance.
