What document must Marines prepare in advance for the Meritorious CPL Board?

The correct answer highlights the importance of personal reflections and accomplishments in a Marine's career. The Personal History Statement is a document that Marines prepare to provide insight into their experiences, achievements, and motivations. It serves as a personal narrative that allows board members to assess candidates beyond just metrics.

This document is crucial for the Meritorious CPL Board because it gives the board context about the individual Marine’s background, contributions to their unit, and their aspirations for future service. It creates a narrative that enhances the Marine's professional profile, thereby supporting their case for meritorious promotion.

In contrast, while the Performance Evaluation Report, Training Record, and Physical Fitness Test results offer valuable metrics of a Marine's performance and fitness, they do not capture the holistic view of a Marine’s career and personal development as effectively as the Personal History Statement does. These documents are important, but they serve different purposes in the promotion process and often complement the narrative that the Personal History Statement provides.
