Today, school districts cannot meet the challenges of an increasingly demanding and diverse clientele without an efficient and effective business and financial framework within which to operate. Well-prepared and dedicated school business officials, working in tandem with other members of the administrative team, can better assure that such a framework is in place. The revised standards presented in this document have been developed to assist training institutions, accrediting agencies, certifying entities, and members of the school business profession to define and achieve educational excellence through the work of the school business official. ASBO (Association of School Business Officials) International considers professional standards for school business officials a key to gaining and maintaining the trust of policymakers and citizens. The Association has been actively developing and disseminating standards for the position of school business official for nearly five decades. The professional standards presented in this document are intended to: (1) assist those currently working in the profession of school business management to perform their duties as expertly as possible; (2) delineate the content of both the pre-service and professional development experiences of those entering or seeking growth in the profession; (3) provide a framework for establishing accreditation standards for higher education institutions involved in training school business officials; and (4) present a model from which to build certification standards for the profession and aid local decision makers in seeking and securing the best person for the school business official position.
