Which abbreviation stands for the standard operating procedure?

• A. STD
• B. SOP
• C. OPS
• D. SRO

Answer: (B)

The abbreviation for standard operating procedure is SOP. A standard operating procedure is a written, step-by-step set of instructions that a crew follows to perform a routine task consistently and safely. SOP is the commonly used acronym because it directly mirrors the full phrase: Standard Operating Procedure. Other options either refer to different things (for example, STD is often used for sexually transmitted disease or standard deviation; OPS is a general shorthand for operations; SRO means other roles like supervisor or student resource officer) and do not denote the formal procedure itself. In practice, you’ll see SOPs that lay out who does the task, what steps to take, when to perform them, and how to verify completion, all to keep operations uniform across the team.
