Working in the hometown school might be a good way to start a career in education. Teaching is a hard job. There are many issues a new teacher has to explore as he begins his path in education. If a young teacher needs to begin in a place that is comfortable for him, then the hometown might be the place to start.
My grandmother always said: If it was good enough for me, it is good enough for you. Modern translation---value what one has. The hometown holds loyalty, friendship, familiarity, family: things to hold in high regard in the early stages of a profession.
A new teacher needs a good support system. Familiarity with the school system is certainly a plus for that issue. Knowing the students, and faculty encourages the new teacher to ask questions and find answers from people he trusts and that offers much needed security. Many times a former teacher will take his old student under his wing and make life for both more interesting.
Being close to family and friends offers a new teacher a life outside of school. If a beginning teacher finds himself in an unfamiliar school and town setting, isolation and even depression could filter into the new career. Saving money in the beginning might mean living at home or in a place that one knows where to find the best bargains.
Of course, there is something to be said for broadening the horizons and striking out for new places. However, there is nothing wrong in visiting those places and then living and working where the person already knows the layout of the land: home.
As Martha Stewart says, "It's a good thing!"
