Principals can work in colleges, universities, high schools, middle schools, elementary schools, pre-schools and in daycare facilities. They can also oversee programs for such institutions as museums, job-training organizations and businesses. They usually have their own office as well as their own secretary, but can also be found working in classrooms, auditoriums and outdoors during special events. They work long hours, often working into the evening. Principals work closely with vice-principals, teachers and other faculty with the common goal of providing a rich and safe learning environment for the students.
