This document provides a framework of educational design principles from which educators and design professionals can structure the content of their educational facility development process, from the earliest strategic and educational planning stage to design, construction, occupancy, and facility management. Each of the 33 educational design principles presented has as its underlying premise that all learning environments should be learner-centered, developmentally- and age-appropriate, safe, comfortable, accessible, flexible, equitable, and cost effective. The principles are divided into the following areas: educational facility planning and design process principles; principles for site and building organization; principles for primary educational space; principles for shared school and community facilities and community spaces; principles related to the character of all spaces; and principles related to site design and outdoor learning spaces.
