The Council of Educational Facility Planners International regularly provides the recommended number of gross square feet (gsf) per student figures. This report provides revised numbers based on responses from its Design Portfolio winners over the past 5 years. Average national averages of square footage space per student for Canada and the continental United States reveal the following ranges: 70.1 to 111.5 gsf for elementary schools buildings; 81.2 to 154.4 gsf for middle schools buildings; and 101.9 to 160.7 gsf for high schools buildings. It also discusses issues about the importance of class size and the implications for educational facility planners; and the factors influencing the area per student, including program characteristics, number of students, and student characteristics.
