This manual is a guide to the development of an instructional program in English for Specific Purposes (ESP). Step-by-step procedures for assessing student needs, setting achievable goals, designing a program, and selecting appropriate materials and activities for the classroom are outlined. The four language skills (listening, reading, speaking, and writing) are described and suggestions for teaching these skills and grammar and study skills are provided. General guidelines for program and classroom management are also presented. A special section addresses the needs of students who are preparing to study abroad, and a resource section reviews materials available to Peace Corps ESP teachers and gives directions for ordering them from the Peace Corps Information Collection and Exchange. The manual is not an exhaustive review of techniques and approaches to teaching English as a second language (ESL), but focuses on the ways in which an ESL program should be structured for the teaching of ESP.
