This document is the result of a national Mainstream English Language Training workgroup. Guidelines and suggestions are presented, in five chapters, for English Language Training (ELT) programs. Chapter one deals with the scope and design of particular ELT programs, taking into account the clients to be served, the needs of the service locale, and ways of prioritizing services. Chapter two suggests criteria for measuring the quality and effectiveness of programs, and chapter three describes procedures for monitoring and evaluating programs in relation to those criteria. Chapter four discusses ways to coordinate ELT programs with other elements of the service delivery system to ensure efficiency and economy through communication among teachers, case managers, job developers, and employers. Chapter five examines the costs of ELT programs and offers help to policymakers responsible for efficient allocation of resources. Appended materials include a set of descriptions stating what students should be able to accomplish with their language skills at various levels, a competency-based core curriculum guide that lists competencies in 5 topical areas for 10 levels of instruction; and a partial list of language proficiency tests.
