A plan of action is presented for teachers of English for Special Purposes (ESP) who wish to strengthen their professional competence, either in ESP strategies and techniques or in content areas in which they might teach. It begins with a list of recommended books, journal articles, periodicals, World Wide Web resources, electronic discussion lists, ESP directories, and providers of ESP training (in Great Britain only). A subsequent section suggests techniques and sources for gathering information about the profession and employment within it and about instructional approaches and content. An example of some of the information an ESP teacher in computer science might seek out is offered. This includes a definition of computer science, names of two major professional associations, introductory books, discourse samples (oral and written), and relevant specialized or high-frequency vocabulary. Contains four references. (MSE)
