Food service, transportation and building cleaning and maintenance are big business and are seen as candidates for privatization. In Ohio, a 30-item questionnaire was developed for the state's school district superintendents. Results were generated from the 143 questionnaires that were returned (70 percent response rate). Findings show that Ohio's school districts use private providers to deliver various management services. Smaller districts rely on private providers for management services that are more highly technical in nature and are used on a less frequent basis. Examples include health services, HVAC maintenance, printing, technology/computer repair, and vehicle maintenance. Services most frequently contracted are those that are infrequently used or require skilled personnel or expensive equipment. Management services are more frequently contracted than instructional services, and larger districts are more open to contracting services than the smaller districts. Trend analysis indicates an increase in privatization of services; additional studies on the ethical and economic challenges of privatization are needed. (Contains 10 references.) (RJM)
