The combination of a main entry with a carefully located, constantly manned administration area provides floor plans that can aid visual supervision of school entries, stairs, and hallways.
The first drawing shows an interior administration desk across from the main entrance. It allows visual access to the lobby doors, stairwells, and perpendicular hallways.
The second drawing shows an administration area located on an outside wall. The administration area can see activities in the lobby, stairs, and hallways almost as effectively as the first scheme, but in addition the administration office commands a supervisory view of outside areas.
The third drawing shows the location of a manned visitors desk in the front lobby. Since it is not part of an adjacent administration area it requires an assigned monitor. The m onitor used (school administrator, teacher, parent, student, or school resource officer) is a factor in the effectiveness of any surveillance.
