Is "sub" short for substitute teacher?

Sub: a term we've all heard, but what does it really mean in the educational world? At its core, "sub" is indeed shorthand for "substitute," a term that encapsulates the role of a temporary educator stepping in to ensure the continuity of learning, regardless of the reason for the original teacher's absence. Substitute teachers are the unsung heroes of the educational system, providing a vital service that keeps classrooms running smoothly.

Substitute teaching is more than just a placeholder position; it's a unique opportunity to impact students' lives positively. Whether it's for a day, a week, or even longer, substitute teachers play a crucial role in maintaining the educational momentum. They bring their own experiences and teaching styles to the table, offering fresh perspectives to students and contributing to their academic journey.
