This document, one of 12 guides that have been developed to facilitate evaluation by and for local education agency (LEA) personnel in Illinois, covers two phases of educational facilities evaluation: the need for new facilities and the adequacy of existing facilities (with the second part receiving greater emphasis). The guide has been designed to aid the person who has responsibility for leading this particular activity. It includes three sections. The first section on preliminary considerations contains a brief explanation of this evaluation activity and the necessary steps to prepare for the evaluation undertaking. Suggestions are included for holding a staff meeting to discuss the activity. The second section of the guide is a procedure/task breakdown, which outlines suggested tasks for conducting the evaluation activity. The third section of this guide contains supporting documents, including information handouts, example documents, and references. (KC)
