Which factor should not influence the selection of training materials?

The selection of training materials is critical to ensuring effective learning outcomes. Personal preference of the officer delivering training should not influence this selection because it can lead to biases that do not necessarily align with the needs of the trainees or the objectives of the training program. Training materials should be chosen based on their ability to effectively communicate necessary information, support diverse learning needs, and adhere to relevant safety standards and regulations.

In contrast, other factors like relevance to current safety standards, visual appeal, and flexibility for various learning styles play significant roles in ensuring that training is effective, engaging, and customizable to accommodate the diverse backgrounds and preferences of all participants. Prioritizing the personal taste of the instructor may overlook these important elements, which can detract from the overall learning experience and potentially compromise safety and compliance.
