There were two purposes of this mixed methods study. The first purpose was to measure the extent of training impact that resulted from management training within a nonprofit environment. To determine potential influences on the extent of training impact, this study included hypotheses that measured specifically whether there was a relationship between trainees' perceptions of success and the factors of management support and accountability. The second purpose was to qualitatively explore and identify factors that enabled or inhibited the application of learned knowledge and skills from the management training to the job. Quantitative data was collected through an online survey that measured the extent that management trainees applied learned knowledge and skills to the job. Survey results showed that 78% of trainees reported that they learned something new, have used it in their work, and have seen results. The most highly applied skills were reported as negotiation techniques, using presentation preparation aids, and analyzing or redesigning work processes. Survey results also led to the conclusion that there was a statistically significant relationship between the level of manager involvement in setting expectations prior to training and the trainees' level of application of learning to the job. There was also a statistically significant relationship between the level of accountability for using training and trainees' level of application of learning to the job. Qualitative data was collected through interviews that explored what factors enabled or inhibited management trainees in applying learned knowledge and skills to the job. The themes (and categories) that emerged as enabling training impact were motivation (trainee characteristics,) self-efficacy (trainee characteristics,) and instructional techniques (training design.) The themes that emerged as inhibiting training impact were instructional techniques (training design,) supervisor and organizational support (work environment,) organizational culture (work environment,) and goal setting (work environment.)
