In this paper, the author's primary focus is on a marketing information system and its potential importance for adult educators. The content is in seven sections. The first two sections briefly introduce information systems in general and their relevance for adult educators. The third section briefly describes general management information systems; the Massachusetts adult basic education information system is provided as an illustration. The next two sections briefly highlight two systems, research or resource information systems and occupational information systems. The ERIC Clearinghouse on Career Education and the ADELL (Adult Education and Lifelong Learning) Clearinghouse are provided as examples for the first system and the Massachusetts Occupational Information System is used to illustrate the latter system. The sixth section describes the marketing information system, outlines key questions for determining the marketing information needs of managers, discusses five functional components of the system (information sources, collection, process, reporting, and information uses), and identifies the dimensions along which the system might be evaluated. The final section discusses the functional components of a marketing information system for continuing education and summarizes some of the benefits anticipated for a continuing education program through the use of the system.
