A STUDY WAS INITIATED TO ORIENT SCHOOL PLANNERS TO A SYSTEMATIC METHOD OF IDENTIFYING AND ANALYZING FACTORS PERTINENT TO SITE SELECTION. THE REVIEW OF LITERATURE REVEALED THAT LITTLE WAS WRITTEN ON THE SUBJECT. A SURVEY OF STATE DEPARTMENTS OF EDUCATION REVEALED THAT TWO STATES HAD PUBLISHED MATERIALS ON SITE SELECTION. HOWEVER, THERE WERE SPECIFIC CASES WHERE CAREFUL STUDIES OF FACTORS IN SITE SELECTION HAD BEEN MADE. OVERALL, TWENTY-FIVE MAJOR FACTORS AND MANY ADDITIONAL FACTORS WERE IDENTIFIED AS AFFECTING SCHOOL SITES. ANOTHER STUDY WAS CONDUCTED FROM 1949 TO 1959 IN SAN MATEO COUNTY, CALIFORNIA. IT WAS CONCLUDED THAT NET SAVINGS RESULTED FROM SITE PURCHASES MADE AT LEAST TWO YEARS IN ADVANCE OF NEED. MAXIMUM SAVINGS WOULD HAVE RESULTED IF PURCHASES HAD BEEN MADE THREE YEARS IN ADVANCE. TEAM APPROACHES INVOLVING EDUCATIONAL AND TECHNICAL EXPERTS ARE RECOMMENDED. PROPER TIMING AND ENVIRONMENTAL FACTORS ARE IMPORTANT CONSIDERATIONS. RATING SHEETS, AERIAL PHOTOGRAPHS, GEOLOGIC AND TOPOGRAPHIC MAPS, TEST BORINGS, AND MODELS CAN PROVIDE INFORMATION TO PLANNERS. A BIBLIOGRAPHY IS INCLUDED.
