The authors describe a project that compared the effects of three interventions on the retirement investment knowledge of public school teachers in the Midwest. They interpret outcomes from three different interventions (online training, site-based workshop, and hybrid of online and site-based). While the study results indicate that program participants increased their investment and retirement knowledge of content presented in the measured approaches, the differences in gains between the interventions were not significant. The authors call for additional research into the investment and retirement education of teachers that employs larger samples and uses valid and reliable instrumentation.
