Catholic elementary and secondary schools are facing increasing costs, more complex administrative demands, and limitations on the amount of revenue that can be expected from traditional sources within the church congregation. To find new sources of support these schools must adopt the techniques of development used successfully by colleges and universities. "Development" involves identifying, coordinating, and expanding the positive forces within an institution to enable that institution to meet its potential. The process includes efforts to improve the institution to match the image desired as well as to communicate that image to those offering support. Development focuses on four points: the quality of the product or service provided, the quality of the institution's management, public perception of the institution, and the institution's ability to take advantage of available resources. Following an introduction to development concepts, this handbook offers practical considerations of public relations, financial resource development, and student recruitment. The school's publics are defined and the uses of public relations calendars and committees are outlined; essential elements in resource development programs are discussed and several specific methods for generating revenue are described; and techniques for persuading students, identifying potential students, and managing recruiting activities are presented.
