This is the 14th in a continuing series of kit-booklets issued to help school boards develop written policies in key subject areas. Because almost everywhere the school department is the biggest buyer in town, written board policies and administrative rules and procedures governing the purchasing process are very important. This booklet provides samples of purchasing policies to encourage thinking in policy terms and to provide working papers to be edited, modified, or adapted to meet local requirements. Subject areas covered include purchasing authority, purchasing guides, vendor lists, specifications, quality control, standardization, bids and quotations, and payment procedures. (Author/JF)
