While part-time substitute teaching can offer a path of entry to a full-time teaching career, it is also a common way to remain involved in the community without experiencing the time pressures placed on full-time teachers. Teachers’ aides assist teachers and administrators in all aspects of their job. Students meet with guidance counselors to discuss family or school dilemmas or their plans for the future. Teachers who have obtained postgraduate degrees may advance to the position of school principal or become a member of the Board of Education. A school principal organizes and manages the school’s faculty and ensures that the school’s goals are met; board members are elected or appointed officials who decide which courses schools will offer and which textbooks the school system will use.
