Why must all entries in the specialty training standard (STS) Column 3 be made in pencil?

The requirement for all entries in the specialty training standard (STS) Column 3 to be made in pencil is primarily to allow for easy updates. Pencil markings can be easily erased and modified without damaging the document, which is essential in a training environment where changes to procedures, standards, or personnel statuses may occur frequently. This flexibility helps ensure that the training records remain current and accurate, reflecting the latest information and requirements.

Using pencil facilitates adjustments as training objectives evolve or when personnel progress through their training programs, ensuring that the STS remains a reliable and up-to-date reference. The other options, while relevant in different contexts, do not accurately capture the primary reason for this specific guideline regarding record maintenance.
