What is the focus of refresher courses in LETP?

Refresher courses in the Local Employee Training Program (LETP) are designed primarily to reinforce existing knowledge while also providing updates on new policies or regulations that may have come into effect since the initial training. This continuous learning approach ensures that employees remain well-informed about current practices and compliance requirements, which is crucial for maintaining safety and operational efficiency in the rail industry.

By revisiting core concepts and integrating any new information, refresher courses help employees stay current in their roles and align their practices with the latest standards and procedures. This focus on reinforcement and updates is essential for effective training programs, allowing employees to confidently apply what they've learned in their day-to-day work.

The other options suggest concepts that don't align with the purpose of refresher courses. For example, skipping training altogether contradicts the intent to maintain knowledge and skills. Likewise, introducing entirely new content or focusing solely on leadership skills would not meet the need for ongoing reinforcement and updates, which are at the heart of refresher courses.
