According to the 2020 Training Industry Report conducted by "Training Magazine," organizations across all industries and sizes have spent $87.5 billion in training per year. The average training budget for a large company was reported at $22 million, whereas a midsized company was $808,000 and a small-sized company reported a yearly budget of $506,000. Although organizations are investing billions of dollars per year in training, deficiencies remain in training and learning transfer. The purpose of this qualitative descriptive study was to explore adult learners' perceptions of the usefulness of engagement tools during and after corporate training from multiple generations of adult learners. The conceptual framework for this study included the intrinsic motivational learning theory, Bandura's self-efficacy theory, Murphy's book entitled "The Power of the Subconscious Mind," and Schlechty's levels of engagement. This conceptual framework was used to support the inquiry, analysis, and interpretation of learners' experiences in using internal engagement practices during and after training. Twelve recruited participants participated in a focus group, and eight of them also participated in face-to-face one-on-one interviews. The findings revealed that all learners, regardless of their generation, found value in using external engagement tools to learn and retain new knowledge and skills. Secondly, the study showed that although external engagement tools were valued, having internal engagement such as internal motivation and self-efficacy were equally important, noting that without the internal engagement, external engagement would not assist learners in retaining new knowledge and skills. The limitations included the learning styles of the learners, population sample, and participants who were not in a current training program. Recommendations for future research include using a mixed method study to explore how multigenerations from the same industries use engagement tools during and after training.
