Growing enrollments, which are leading to overcrowding at many existing schools, are also a cause for concern. When addressing problems of inadequate available resources, administrators serve as advocates to build new schools or repair existing ones. Schools continue to be involved with students' emotional welfare as well as their academic achievement. As a result, principals face responsibilities outside the academic realm. With the help of community organizations, some principals have established programs to combat the increase in crime, drug and alcohol abuse, and sexually transmitted disease among students.
Assistant principals aid the principal in the overall administration of the school.
Depending on the number of students, the number of assistant principals a school employs may vary. They are responsible for programming student classes, ordering textbooks and supplies, and coordinating transportation, custodial, cafeteria, and other support services. They usually handle discipline, attendance, social and recreational programs, and health and safety. They also may counsel students on personal, educational, or vocational matters. Administrators in school district central offices manage public schools under their jurisdiction .
