What is a requirement for submitting a roster?

Submitting a roster in the form of a comma-separated values (CSV) file is a requirement because CSV files are a standard format that allows for easy parsing and manipulation of data. This format is widely compatible with various data management systems, making it convenient for processing large amounts of information efficiently. The CSV format supports a structured approach to data entry, where each piece of data can be clearly delineated, allowing for systematic analysis or integration into databases.

In contrast, the other options are not practical or standard requirements for roster submission. A PDF file may not be suitable for data processing, as it is more geared toward fixed layouts. Verbal submissions lack the clarity and permanence of written files, and including photographs would create unnecessary complexity and could violate privacy standards. Thus, the requirement to use a CSV file ensures that the roster is submitted in a clear, analyzable format.
